Give C++ access to the RTOS's absolute timebase, reducing the need to
run private Timers and similar. Allows wait_until functionality, and
makes it easier to avoid time drift.
Place it in a new header and namespace in case we want more kernel
functions in future.
Try to cover over the breaking API change potentially upcoming in
CMSIS-RTOS 2.1.1, when it reduces the tick count from 64-bit to 32-bit.
(See https://github.com/ARM-software/CMSIS_5/issues/277)
Explicitly state that ticks are milliseconds in mbed OS, despite CMSIS
RTOS 2 permitting different tick rates.
See also https://github.com/ARMmbed/mbed-os/pull/3648 (wait_until
for condition variables) and
https://github.com/ARMmbed/mbed-os/issues/5378 (EventQueue should
use RTOS tick count).
Documentation states that nsapi_dns_query_multiple returns the number of
addresses found on success - it was returning 0.
Overloads using SocketAddress are relying on the return value, meaning
those calls didn't work at all.
Fixes#5921.
Remove the assert that the tick count of the OS matches the tick
count of the tickless timer as this occurs frequently when
debugging. This is because the function svcRtxKernelResume
only increments the OS's tick count until the next wakeup event
so if the device was halted by a debugger past the next wakeup
event the tick counts will be out of sync.

And the old behaviour of displaying the memap table can be brought back
by passing the --stats-depth parameter
Default SERIAL pins are now available for ADC and PWM

Alternative pins have been also defined
