When moving to the second heap region due to overflowing the first
region, the `_sbrk` implementation assumed the allocation would fit in
the second region, and didn't check for that overflowing too.
Problem revealed in `stats_heap` test with GCC 8 on K64F - the allocation
attempt for 1GiB crashed, as `_sbrk` indicated 1GiB was available at the
start of the second region.
second region.
Presumably older versions of newlib fault that allocation attempt before
passing to `_sbrk`.
While there, adjust the code to not use a separate static `bool`, saving
RAM. We can track with just one pointer, as order of the two regions is
fixed, and already relied on by newlib.
The ARMC6 compiler inadvertently introduces the `_scanf_mbtowc` symbol
to the build. The commit provides a weak definition of the symbol to
satisfy the linker whenever the symbol is included. This affects ARM
Compiler 6 version 6.12 and earlier.
The compiler error was previously observed when the MICROLIB library is
used with the uARM toolchain. However, the weak definition was put in
`mbed-os/rtos` which is not included when the bare metal profile is used.

Replace the sleep_manager_can_deep_sleep() with !_deep_sleep_locked.
Indeed, if we know we've taken the lock because we're using us_ticker,
no need to do the early wake.
Updated comments accordingly.
When next SysTimer wake-up is scheduler far enough, always consider
that deep sleep may be entered and program an early wake-up.
So that even if deep sleep is only allowed some time later, it can be
entered. If not doing this, then the deep sleep would be prevented by
SysTimer itself and may not be entered at all.
This has been proved to happen in a simple blinly example.
* Modify Doxygen grouping of `drivers` Public/Internal APIs
* Correct classification of `mbed_events.h`
* Amend name of Doxygen group containing Device Key API
* Classify `CallChain.h` as public API and relocate file
* Remove Doxygen group from `equeue_platform.h` as it has no Doxygen compliant documentation
* Move USB target specific code back to `usb/device/targets`
* Change Doxygen groups structure, splitting first by Public/Internal
This commit also does the following:
* groups the documentation of related API
* moves `events/internal/equeue.h` to `events/equeue.h`
* merges `events/source/README.md` to `events/README.md`
Also includes:
* rename `mbed_sleep_manager.c` to `mbed_power_mgmt.c` to match its
header file
* create Doxygen groups for public and internal APIs
* use relative path to include header files where inconsistent
* update references to internal APIs throughout libraries
* update the copyright year for all modified files
* Fixed wrapper functions for IAR
* Fixed and renamed profile to minimal-printf.json
* Moved minimal-printf under platform
* Removed minimal-printf/mbed_lib.json
* Modified exporter template to work with partial profile
* Prevented optimization of printf to avoid compiler function substitution
