Merge pull request #13254 from LDong-Arm/move_nanostack-libservice ...

Move nanostack-libservice into connectivity/libraries

Unittests and Astyle: ...

- Update the header reference and source reference in cmake
- Update astyleignore to ignore blockdevice UNITTESTS
- Removed the redundant debug log

Merge pull request #13244 from rajkan01/storage_restructure_initial ...

Move storage from features into mbed-os root directory

Stroage unittest directory restructure ...

- Move UNITTESTS/features/storage to UNITTESTS/storage
- update the .cmake files to refer the new directory

UNITTESTS: update paths to nanostack-libservice

UNITTESTS: Add comment for glob pattern

Allow unittest.cmake from the whole mbed-os

Remove references to mbed-crypto ...

Add kvstore/conf to unittest includes ...

The unittests compile DirectAccessDeviceKey.cpp which depends on
kv_config.h, which lives in features/storage/kvstore/conf

unittests: fix windows build ...

- set equeue platform to posix for MINGW
 - enable PRIx formatting globally
 - remove redundant Semaphore implementation

Valgrind support added for unittests ...

Added an option to select Valgrind to be used for unittests from command line

Unittest configuration mechanism improved ...

Earlier all unittests ended up having all flags in common from all unittest targets.
This is now improved by using googletest provided mechanism to set build time compile options
All cmake files have been modified to reflect changes (when needed)

Could not figure out a syntax for {0x00, 0x00, ..., 0x00} intitializer list yet,
so those needs to be setup by updating C/CXX flags.

Remove extra GCC arquements. ...

"--coverage" is synonym to "-fprofile-arcs -ftest-coverage"
https://gcc.gnu.org/onlinedocs/gcc/Instrumentation-Options.html

This was causing extra compilation warnings on CLANG.

update googletest to v1.8.1

crypto: Add Mbed Crypto includes to unit tests ...

Mbed Crypto also supplies include files. Ensure that our unit tests can
find those headers.

Drivers/Events/RTOS Public and internal APIs cleanup (#10955) ...

Separate drivers, events, and rtos internal APIs from public APIs.

* Move source files to source subdirs
* Move internal headers to internal subdirs
* Add Doxygen comments for documenting internal and public APIs
* Remove source code from header files in order to remove include pre-processor directives
that included header files not directly used by said header files
* Explicitly include header files instead of implicit inclusions via third-party header files.

Release Notes

This will break user code that was using an internal API as the internal header files have been moved.
This will only break if the user was including the header file using a namespace (i.e #include "foo/bar.h" instead of #include "bar.h"

Add mstd_xxx headers to unit tests ...

Stripped down headers that route through to `std` forms more - eg
no local implementation of `atomic` or `mutex`.

RTOS API for bare metal ...

Provide partial RTOS API for bare metal builds - things that
can be done in a single threaded environment.

Allows more code to work in both RTOS and bare metal builds without
change, and in particular gives easy access to the ability to
efficiently wait for something occurring in interrupt.

Available in bare-metal:
* ThisThread
* osThreadFlagsSet to set flags on main thread (can be set from IRQ)
* EventFlags (can be set from IRQ)
* Semaphores (can be released from IRQ)
* Mutex (dummy implementation)

Not useful:
* ConditionVariable (could only be signalled from 2nd thread)
* RtosTimer (calls in a second thread context)
* Thread

Unimplemented:
* Mail, Queue, MemoryPool

Possible future work:
* ConditionVariableCS to act as IRQ signalled ConditionVariable

Set unit tests to C++14 ...

Adjust some non-C++11-compatible code that failed as a result.

Hw Watchdog UnitTest cases ...

-Added the unit test case for testing Hw watchdog
    -Added the supported stubs files

Including CTest explicitly ...

enable_test() seems to include CTest framework in the CMakeLists.txt but
that would result in inconsistencies and CTest framework will not be
able to find DartConfiguration file or MemCheck tool.

Including CTest framework explicitely in the CMakeLists.txt seems to
solve the issue.

Cellular: fixing unit test after refactor.

Lorawan unittests

add auto-naming of unit test suites

cellular unittests ported to googletest framework

Fix SocketAddress unittests ...

Add ip4tos() and stoip4() into unittests.
NOTE: Probably should have been stubbed but this way we can also
test these helper functions.

Add unit testing framework
