Deprecate wait() in favour of acquire(), try_acquire(),
try_acquire_for() and try_acquire_until().
Brings Semaphore more into line with CMSIS-RTOS 2 (which uses "acquire"),
itself (as it has "release"), and other classes having "try", "try for"
and "try until".
Also steps away from vague "wait" term - the primary operation here is
to acquire the semaphore, and this will of course sleep.
Get rid of a volatile, and use atomics to synchronise with the interrupt
routine instead.
Useful as a non-RTOS basic compilation check for the atomics - the
fuller atomic test relies on the RTOS.
These are platform tests, but rely on the RTOS to run multiple threads
to exercise it.
(The atomics are still useful in non-RTOS, to protect against interrupt
handlers, but testing versus other threads is easier. The implementation
is the same either way, so doesn't seem worth testing non-RTOS
specifically).
The DEVICE_FOO macros are always defined (either 0 or 1).
This patch replaces any instances of a define check on a DEVICE_FOO
macro with value test instead.

ARM C library is really good at optimising out calls to underlying
seek. The only ones we were actually detecting in the empty file case
were the ones that the default FileHandle::size() made itself during
the SEEK_END case.
When we implement TestFile::size() directly, we will no longer see
a single seek call from the ARM C library in the empty file case, so
remove those tests.
Beef up the non-empty file case, adding checks that we are making
underlying read+write calls in the correct position, as a proxy for
direct checks for underlying seek being called.
mbed.h was added in test, via greentea and utest header files. 'mbed.h' is removed
from header files and required header file and namespace is added to CPP/C files
Static Thread methods and signal methods have been deprecated. Remove
all references in the main code, and most of the tests. Some tests of
the deprecated APIs themselves remain.
You are allowed in POSIX / ANSI C to read and write on the same stream, but you
have to do an fseek in between read and write call (getc->fseek->putc)
Thanks @Alex-EEE for sharing the fix: https://github.com/ARMmbed/mbed-os/pull/7749
Added test case for verification of the behavior
Heap statistics are used for analysing heap stats, but it doesn't tell anything
about real heap usage or malloc overheads. Adding `overhead_size` element
will help users to get the real heap usage.
The new configuration make Error history tracking switched off by default and enabled by using the config flag MBED_CONF_PLATFORM_ERROR_HIST_ENABLED.
Config flag MBED_CONF_PLATFORM_ERROR_ALL_THREADS_INFO enables printing info of all threads. This will be turned off by default.
With small wait time at the start, chances are that device does not
enter sleep and idle time is zero. Increasing wait time to make sure
device goes to sleep.
