This is a hack to get debug builds applications that use uVisor to work.
The assertions in core_util_critical_section fail because interrupts can't
actually be disabled from unprivileged mode.
Without this hack, core_util_critical_section_enter() calls
mbed_assert_internal() when the assertion fails, which calls
core_util_critical_section_enter() again, which calls
mbed_assert_internal() again; this is infinite recursion.
core_util_critical_section_enter needs some fixing.
If you don't specify the start address of a section explicitly, that
section can end up at different addresses depending on its alignment. If
the alignment of a section is not explicitly set, it inherits it from
the element with the highest alignment inside that section.
Since the uVisor code is in the .text section, and it *must* end up at a
known location, we set the start address of .text to 0x410, which is the
value that the uVisor binary expects.

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:
d0b7b3b497 -
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.

This fix is a solution for issue #816 when having two separate IRQ handlers
in Timers (UPDATE Irq and OutputCompare Irq). The update priority needs to
be higher to avoid undefined behaviours.

This is a partial revert of 07b841b and currently we are only reverting the
STM32F0xx family because new fix will be presented that's why we want to keep,
still the original solution only F1xx family (it will be fixed in future).

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.
