- Added mbed-events library
Added mbed-events from https://github.com/ARMMbed/mbed-events. Changes
from upstream:
- the whole code is licensed under the Apache license. Sources and
headers were updates with this information.
- removed the porting layers for Windows and FreeRTOS and the references
to these porting layers in equeue_platform.h.
- moved the TESTS directory in mbed-events to the TESTS directory of
mbed-os.

+## The mbed-events library ##
+
+The mbed-events library provides a flexible queue for scheduling events.
+
+``` cpp
+#include "mbed_events.h"
+#include <stdio.h>
+
+int main() {
+ // creates a queue with the default size
+ EventQueue queue;
+
+ // events are simple callbacks
+ queue.call(printf, "called immediately\n");
+ queue.call_in(2000, printf, "called in 2 seconds\n");
+ queue.call_every(1000, printf, "called every 1 seconds\n");
+
+ // events are executed by the dispatch method
+ queue.dispatch();
+}
+```
+
+The mbed-events library can be used as a normal event loop, or it can be
+backgrounded on a single hardware timer or even another event loop. It is
+both thread and irq safe, and provides functions for easily composing
+independent event queues.
+
+The mbed-events library can act as a drop-in scheduler, provide synchronization
+between multiple threads, or just act as a mechanism for moving events out of
+interrupt contexts.
+
+### Usage ###
+
+The core of the mbed-events library is the [EventQueue](EventQueue.h) class,
+which represents a single event queue. The `EventQueue::dispatch` function
+runs the queue, providing the context for executing events.
+
+``` cpp
+// Creates an event queue enough buffer space for 32 Callbacks. This
+// is the default if no argument was provided. Alternatively the size
+// can just be specified in bytes.
+EventQueue queue(32*EVENTS_EVENT_SIZE);
+
+// Events can be posted to the underlying event queue with dynamic
+// context allocated from the specified buffer
+queue.call(printf, "hello %d %d %d %d\n", 1, 2, 3, 4);
+queue.call(&serial, &Serial::printf, "hi\n");
+
+// The dispatch function provides the context for the running the queue
+// and can take a millisecond timeout to run for a fixed time or to just
+// dispatch any pending events
+queue.dispatch();
+```
+
+The EventQueue class provides several call functions for posting events
+to the underlying event queue. The call functions are thread and irq safe,
+don't need the underlying loop to be running, and provide an easy mechanism
+for moving events out of interrupt contexts.
+
+``` cpp
+// Simple call function registers events to be called as soon as possible
+queue.call(doit);
+queue.call(printf, "called immediately\n");
+
+// The call_in function registers events to be called after a delay
+// specified in milliseconds
+queue.call_in(2000, doit_in_two_seconds);
+queue.call_in(300, printf, "called in 0.3 seconds\n");
+
+// The call_every function registers events to be called repeatedly
+// with a period specified in milliseconds
+queue.call_every(2000, doit_every_two_seconds);
+queue.call_every(400, printf, "called every 0.4 seconds\n");
+```
+
+The call functions return an id that uniquely represents the event in the
+the event queue. This id can be passed to `EventQueue::cancel` to cancel
+an in-flight event.
+
+``` cpp
+// The event id uniquely represents the event in the queue
+int id = queue.call_in(100, printf, "will this work?\n");
+
+// If there was not enough memory necessary to allocate the event,
+// an id of 0 is returned from the call functions
+if (id) {
+ error("oh no!");
+}
+
+// Events can be cancelled as long as they have not been dispatched. If the
+// event has already expired, cancel has no side-effects.
+queue.cancel(id);
+```
+
+For a more fine-grain control of event dispatch, the `Event` class can be
+manually instantiated and configured. An `Event` represents an event as
+a C++ style function object and can be directly passed to other APIs that
+expect a callback.
+
+``` cpp
+// Creates an event bound to the specified event queue
+EventQueue queue;
+Event<void()> event(&queue, doit);
+
+// The event can be manually configured for special timing requirements
+// specified in milliseconds
+event.delay(10);
+event.period(10000);
+
+// Posted events are dispatched in the context of the queue's
+// dispatch function
+queue.dispatch();
+
+// Events can also pass arguments to the underlying callback when both
+// initially constructed and posted.
+Event<void(int, int)> event(&queue, printf, "recieved %d and %d\n");
+
+// Events can be posted multiple times and enqueue gracefully until
+// the dispatch function is called.
+event.post(1, 2);
+event.post(3, 4);
+event.post(5, 6);
+
+queue.dispatch();
+```
+
+Event queues easily align with module boundaries, where internal state can
+be implicitly synchronized through event dispatch. Multiple modules can
+use independent event queues, but still be composed through the
+`EventQueue::chain` function.
+
+``` cpp
+// Create some event queues with pending events
+EventQueue a;
+a.call(printf, "hello from a!\n");
+
+EventQueue b;
+b.call(printf, "hello from b!\n");
+
+EventQueue c;
+c.call(printf, "hello from c!\n");
+
+// Chain c and b onto a's event queue. Both c and b will be dispatched
+// in the context of a's dispatch function.
+c.chain(&a);
+b.chain(&a);
+
+// Dispatching a will in turn dispatch b and c, printing hello from
+// all three queues
+a.dispatch();
+```

+## The equeue library ##
+
+The equeue library is designed as a simple but powerful library for scheduling
+events on composable queues.
+
+``` c
+#include "equeue.h"
+#include <stdio.h>
+
+int main() {
+ // creates a queue with space for 32 basic events
+ equeue_t queue;
+ equeue_create(&queue, 32*EQUEUE_EVENT_SIZE);
+
+ // events can be simple callbacks
+ equeue_call(&queue, print, "called immediately");
+ equeue_call_in(&queue, 2000, print, "called in 2 seconds");
+ equeue_call_every(&queue, 1000, print, "called every 1 seconds");
+
+ // events are executed in equeue_dispatch
+ equeue_dispatch(&queue, 3000);
+
+ print("called after 3 seconds");
+
+ equeue_destroy(&queue);
+}
+```
+
+The equeue library can be used as a normal event loop, or it can be
+backgrounded on a single hardware timer or even another event loop. It
+is both thread and irq safe, and provides functions for easily composing
+multiple queues.
+
+The equeue library can act as a drop-in scheduler, provide synchronization
+between multiple threads, or just act as a mechanism for moving events
+out of interrupt contexts.
+
+## Documentation ##
+
+The in-depth documentation on specific functions can be found in
+[equeue.h](equeue.h).
+
+The core of the equeue library is the `equeue_t` type which represents a
+single event queue, and the `equeue_dispatch` function which runs the equeue,
+providing the context for executing events.
+
+On top of this, `equeue_call`, `equeue_call_in`, and `equeue_call_every`
+provide easy methods for posting events to execute in the context of the
+`equeue_dispatch` function.
+
+``` c
+#include "equeue.h"
+#include "game.h"
+
+equeue_t queue;
+struct game game;
+
+// button_isr may be in interrupt context
+void button_isr(void) {
+ equeue_call(&queue, game_button_update, &game);
+}
+
+// a simple user-interface framework
+int main() {
+ equeue_create(&queue, 4096);
+ game_create(&game);
+
+ // call game_screen_udpate at 60 Hz
+ equeue_call_every(&queue, 1000/60, game_screen_update, &game);
+
+ // dispatch forever
+ equeue_dispatch(&queue, -1);
+}
+```
+
+In addition to simple callbacks, an event can be manually allocated with
+`equeue_alloc` and posted with `equeue_post` to allow passing an arbitrary
+amount of context to the execution of the event. This memory is allocated out
+of the equeue's buffer, and dynamic memory can be completely avoided.
+
+The equeue allocator is designed to minimize jitter in interrupt contexts as
+well as avoid memory fragmentation on small devices. The allocator achieves
+both constant-runtime and zero-fragmentation for fixed-size events, however
+grows linearly as the quantity of differently-sized allocations increases.
+
+``` c
+#include "equeue.h"
+
+equeue_t queue;
+
+// arbitrary data can be moved to a different context
+int enet_consume(void *buffer, int size) {
+ if (size > 512) {
+ size = 512;
+ }
+
+ void *data = equeue_alloc(&queue, 512);
+ memcpy(data, buffer, size);
+ equeue_post(&queue, handle_data_elsewhere, data);
+
+ return size;
+}
+```
+
+Additionally, in-flight events can be cancelled with `equeue_cancel`. Events
+are given unique ids on post, allowing safe cancellation of expired events.
+
+``` c
+#include "equeue.h"
+
+equeue_t queue;
+int sonar_value;
+int sonar_timeout_id;
+
+void sonar_isr(int value) {
+ equeue_cancel(&queue, sonar_timeout_id);
+ sonar_value = value;
+}
+
+void sonar_timeout(void *) {
+ sonar_value = -1;
+}
+
+void sonar_read(void) {
+ sonar_timeout_id = equeue_call_in(&queue, 300, sonar_timeout, 0);
+ sonar_start();
+}
+```
+
+From an architectural standpoint, event queues easily align with module
+boundaries, where internal state can be implicitly synchronized through
+event dispatch.
+
+On platforms where multiple threads are unavailable, multiple modules
+can use independent event queues and still be composed through the
+`equeue_chain` function.
+
+``` c
+#include "equeue.h"
+
+// run a simultaneous localization and mapping loop in one queue
+struct slam {
+ equeue_t queue;
+};
+
+void slam_create(struct slam *s, equeue_t *target) {
+ equeue_create(&s->queue, 4096);
+ equeue_chain(&s->queue, target);
+ equeue_call_every(&s->queue, 100, slam_filter);
+}
+
+// run a sonar with it's own queue
+struct sonar {
+ equeue_t equeue;
+ struct slam *slam;
+};
+
+void sonar_create(struct sonar *s, equeue_t *target) {
+ equeue_create(&s->queue, 64);
+ equeue_chain(&s->queue, target);
+ equeue_call_in(&s->queue, 5, sonar_update, s);
+}
+
+// all of the above queues can be combined into a single thread of execution
+int main() {
+ equeue_t queue;
+ equeue_create(&queue, 1024);
+
+ struct sonar s1, s2, s3;
+ sonar_create(&s1, &queue);
+ sonar_create(&s2, &queue);
+ sonar_create(&s3, &queue);
+
+ struct slam slam;
+ slam_create(&slam, &queue);
+
+ // dispatches events from all of the modules
+ equeue_dispatch(&queue, -1);
+}
+```
+
+## Platform ##
+
+The equeue library has a minimal porting layer that is flexible depending
+on the requirements of the underlying platform. Platform specific declarations
+and more information can be found in [equeue_platform.h](equeue_platform.h).
+
+## Tests ##
+
+The equeue library uses a set of local tests based on the posix implementation.
+
+Runtime tests are located in [tests.c](tests/tests.c):
+
+``` bash
+make test
+```
+
+Profiling tests based on rdtsc are located in [prof.c](tests/prof.c):
+
+``` bash
+make prof
+```
+
+To make profiling results more tangible, the profiler also supports percentage
+comparison with previous runs:
+``` bash
+make prof | tee results.txt
+cat results.txt | make prof
+```
