Before:
Callback<void()> a = callback(obj, member)
Callback<void()> b = callback(context, function)
After:
Callback<void()> a = callback(obj, member)
Callback<void()> b = callback(function, context)
This ordering is more intuitive based on feedback from users. This order
was initially considered but proved problematic when integrated with
other variable arguments in attach functions.
With `callback` as a separate convenience function, this style
no longer presents a problem.
Before, rtx calls would hard fault in critical sections when an svc
instruction was attempted with interrupts disabled.
Required changes:
- Added check for CPSR I bit in cortex A rtx
- Added check for PRIMASK in cortex M rtx
- Modified critical sections in cortex M rtx to be recursive
(already recursive in cortex A)
Disintegrate global RTX target config. Move per-target fragment
to mbed_rtx.h under each vendor's directory.
One mbed_rtx.h is defined for each vendor at this moment, however,
the granularity of mbed_rtx.h can be per-chip, or per-board
if necessary.

Update the Thread::start function to gracefully handle the failed
creation of a thread when there are no TCBs left. This patch does
the following:
1. Set memory handles to NULL after free to prevent double free
2. Post to the release semaphore so anything that tries to join this
thread will join immediately
3. Remove dead return path since the new operator should never
return NULL (it should trap instead)
Add an RTX hook which gets called when a thread terminates. Add
the function Thread::attach_terminate_hook() to allow users to attach
a hook to this event at runtime.
Add the function osThreadGetInfo to allow various Thread information
to be queried. This includes stack size and maximum stack usage among
other things.
Note - for Cortex-A devices the worst case stack usage is not
available.
Add the functions osThreadsEnumStart, osThreadEnumNext and
osThreadEnumFree to allow enumeration of running threads. Protect
thread creation, thread exit and thread termination with a mutex
so threads are not created or destroyed while an enumeration is
ongoing.
In Thread::terminate() release the join semaphore before terminating
the thread. This allows the join semaphore to be properly signaled in
the case where a thread is terminating itself.
In rtos/rtx/TARGET_CORTEX_M/RTX_CM_lib.h, Image$$ARM_LIB_HEAP$$Base/Image$$ARM_LIB_HEAP$$Length will cause zero memory allocation.
Fix it with Image$$ARM_LIB_HEAP$$ZI$$Base/Image$$ARM_LIB_HEAP$$ZI$$Length. This is to place heap at external SRAM.
User feedback indicated that the previous deprecation notices
were confusing and mislead migration from the old style of thread
spawning.
The deprecation notices were updated to emphasize the replacement
functions, and examples of correct usage were added in the doxygen.
Additionally, the following changes were don to avoid combinatorial
explosion in function overloads as a result of adding cv-qualifiers:
- Added convenience function for inferred type
- Deprecated callback overloads qhere cv-qualifiers are not scalable
Supported overloads:
callback(void (*f)(A...));
callback(const Callback<R(A...)> &);
callback(T *t, void (*f)(T*, A...));
callback(const T *t, void (*f)(const T*, A...));
callback(volatile T *t, void (*f)(volatile T*, A...));
callback(const volatile T *t, void (*f)(const volatile T*, A...));
callback(T *t, void (T::*f)(A...));
callback(const T *t, void (T::*f)(A...) const);
callback(volatile T *t, void (T::*f)(A...) volatile);
callback(const volatile T *t, void (T::*f)(A...) const volatile);
Silence the following compiler warning:
[Warning] RTX_CM_lib.h@807,5: implicit declaration of function 'atexit' [-Wimplicit-function-declaration]

From the discussion on issue #2068:
Functions marked deprecated in the mbed library should notate when
the deprecation was started to allow efficient removal once a set
amount of time has expired.
Added the following macro:
MBED_DEPRECATED_SINCE("version", "message string")
Example usage:
MBED_DEPRECATED_SINCE("v5.1", "don't foo any more, bar instead")
void foo(int arg);
Adopted in existing deprecations:
- FunctionPointer
- RtosTimer
- Thread
