Various toolchains supported in MBED don't followthe same initialization
steps. This can have impacts on platform behavior.
For STM32, it is needed to call the HAL_Init() _after_ the RAM has been
initialized (sdata from flash / zero initialized data) and _before_ the C++
objects are being created, especially if those objects require support
of tickers for instance.
In GCC and IAR, this was done in previous commit to avoid HAL_Init()
to be called twice.
In ARM this there is no hook defined in MBED yet to place the call.
The proposal is to take benefit of the library's
_platform_post_stackheap_init function that is going to be called before
__rt_lib_init where the C++ object init is done (__cpp_initialize__aeabi_)
In case of mbed with rtos, the __rt_entry is redefined so we need to add
the call to _platform_post_stackheap_init.
This series should solve issue reported here:
STM32 (At least F401) breaks if Tickers are activated in a global object #2115
In uARM, the library's hook _platform_post_stackheap_init does not seem to
exist and I couldnot find a documentation describing the initialisation
flow. All we know is that _open is called after RAM init and before the
C++ init, so this is a working placeholder.
This is maybe not acceptable so a uARM lib expert may propose a better
hook to fullfil the requirement.
At least this is a workign setup.

In GCC, this is easily done because SystemInit is called after the ram
initialisation, so HAL_Init does not need to called from mbed_sdk_init.
this is covered by the changes in mbed_overrides.c files.

Returning a wifi access point without information regarding the
security type is only valid if the security type is unknown (from
the perspective of the network-socket API). For clarity in situations
in which scan may return an unsupported, but known security type,
type name has been changed to NSAPI_SECURITY_UNKNOWN.
