sleep_manager_racecondition test fix for devices with low CPU clock
This RP contains fix for sleep_manager_racecondition test
for very slow devices (like NRF51). It fixes the test itself
as well as side effects of fix introduced in
#5046 (us ticker: fix fire interrupt handling)
The idea of the test was to test race condition between main thread
and interrupt handler calling the same function.
To efficiently test this, each handler call should interrupt
main thread to make race more likely.
On very slow devices (like NRF51) when we set very low ticker period
(e.g less then 1000us for NRF51) there is no much time for thread scheduling.
On such slow devices, setting period to 500 us cause that
main thread is scheduled very rarely and only handler is
constantly called making test unreliable.
Fix introduced in #5046 (us ticker: fix fire interrupt handling)
changed fire_interrupt function implementation causing more
interrupt tailing thus even less time for main thread scheduling.
After introduction of #5046 (us ticker: fix fire interrupt handling)
when running sleep_manager_racecondition test on NRF51
(with ticker1.attach_us(&sleep_manager_locking_irq_test, 500);)
test is failing with timeout due to the fact that interrupt
handler is constantly called and main thread is never scheduled.
Current behaviour ends up undefined when the constructor leaves early.
Now FilePath just discards leading slashes and otherwise asserts if the
path is bad.
Some toolchains (GCC) may emit error messages with unicode symbols based on
the your localization settings. Instead of being passed to the user as is,
the unicode causes an exception.
This commit adds the UART driver and updates the UART HAL implementation
to use this driver.
It also removes legacy definitions.

This commit adds the SPI driver which is now called by the SPI HAL
implementation.
It also removes legacy definitions.

This commit adds the GPIO drivers. The HAL implementations
(gpio_api.c, gpio_irq_api.c, port_api.c) now call these drivers.
Legacy definitions have been removed.
Serial HAL implementation has been changed to compile at this stage.

The HAL implementation (us_ticker.c and lp_ticker.c) now calls function
in cmsdk_ticker.c file. This file contains the necessary logic to be
able to only use one hardware timer (CMSDK timer) per mbed ticker.
This commit also updates the timer driver and removes legacy definition.
