The malloc lock functions were not declared as extern "C" so they
are not getting linked to the standard library. Add extern "C" to
fix this.
This bug was introduced in the commit:

Fix duplicate symbols for malloc lock and unlock
The current version of MBED test environment requires LEDs to be present
in the platform.
Beetle HW does not provide any user programmable LEDs. This patch provides an
emulation of the feature by using dummy PINs.

Add a virtual destructor to classes which have a virtual lock and
unlock. Remove the virtual qualifier from functions in
InterruptManager since this class cannot be extended.
When the malloc lock and unlock functions are inside a library they
conflict with the standard libraries weak version of these functions.
This is because of the way weak references are handled by the linker.
This patch renames the lock and unlock functions defined inside RTX
so they do not conflict. A thunk inside retarget.cpp then calls the
RTX functions. This problem does not occur with retarget.cpp since
it is always build into an object file rather than a library file.
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.
The main stack ends at the start of the heap. In some configurations
this causes the guard word to be overwritten when memory is allocated.
This causes an OS error in RTX since it appears that the main stack
overflowed.
This patch moves the main stack to the upper 1/4th of the heap which
prevents the guard word from getting overwritten.
The rtx SVC_Handler for IAR clobbers r0-r3 despite the number of
arguments. However, in the SVC calls, the __swi function is declared
with fewer arguments. IAR doesn't understand that the other registers are
clobbered and stores variables in r0-r3 when multiple SVCs are
dispatched in a single function.
This bug was noticed in osThreadExit, which hard-faults on IAR,
preventing any threads from exiting.
