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.

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.
Silence the following compiler warning:
[Warning] RTX_CM_lib.h@807,5: implicit declaration of function 'atexit' [-Wimplicit-function-declaration]

Create the wrapper class SingletonPtr. This provides a safe way to
declare and use singletons. This class allows both the lazy
initialization of a singleton, and allows the singleton to be
garbage collected by the linker if it is never referenced.
This patch also updates the HAL to use SingletonPtr when declaring
singleton mutexes.
We changed the stack size of main thread for RZ_A1H.
We changed "OS_MAINSTKSIZE" from 2048 to 4096.
Because stack shortage was found in the automatic test by the CI System .
The define OS_TCB_SIZE does not match the real stack size. This
leaves the system with less than OS_TASKCNT TCBs and prevents
a single thread configuration. This updates OS_TCB_SIZE to the
correct value to fix the problem.
Wrap software_init_hook so that it can be used or extended from outside the
RTOS. This is desirable so that code can be added to the software_init_hook
without making the RTOS depend on new features or libraries.
