Many test stub functions are meant to return a value, but weren't. Clang
would generate a warning for each instance where we weren't returning
anything in a function that was meant to return a value.
warning: non-void function does not return a value [-Wreturn-type]
For a specific example, my_radio::time_on_air() is supposed to return a
uint32_t, but wasn't returning anything. We'll return a zero instead of
relying on undefined behavior.
Without this, clang 11.0.1 was generating a virtual function
implementation with a `ud2` instruction to abort at run-time, causing
some execution of some unit tests to abort.

- Armclang is not working when we add gcov as target_link_libraries,
modified to pass as linker options with --coverage so it can work armclang and gcc
Note that documentation for random_max_start_delay config setting has
been changed to indicate that the setting is in seconds, and always has
been. No functional change.
Baseline for the tests is similar to the TDBStore.
Differing from TDBStore moduletests, FileSystemStore doesn't include
tests for reserved data or corrupting the blockdevice, as it corrupts
the filesystem also.
The rather fiddly `nsapi_create_stack` template + overloads used during
socket formation don't inline their core, which is the identity operation
for `NetworkStack *` itself. Make code generation easier by having that
core be inline.
Moved the existing BufferedBlockDevice to features/storage unittests and switched it to gmock.
Added gmock-based unit tests to all other BlockDevice classes.
SlicingBlockDevice test left as a module test.
