The rtc_drv on x86 can now by used to also set the RTC. If the config
attribute 'allow_setting_rtc' is set to 'yes' the driver will update
the RTC from the content of the 'set-rtc' ROM module. A valid ROM must
contain a top node with the following attributes: 'year', 'month',
'day', 'hour', 'minute' and 'second'.
* Only rudimentary checking of the provided values is done.
* '12H' mode is not supported.
Fixes#3438.
Since the timer and timeout handling is part of the base library (the
dynamic linker), it belongs to the base repository.
Besides moving the timer and its related infrastructure (alarm, timeout
libs, tests) to the base repository, this patch also moves the timer
from the 'drivers' subdirectory directly to 'src' and disamibuates the
timer's build locations for the various kernels. Otherwise the different
timer implementations could interfere with each other when using one
build directory with multiple kernels.
Note that this patch changes the include paths for the former os/timer,
os/alarm.h, os/duration.h, and os/timed_semaphore.h to base/.
Issue #3101
Instead of returning an uint64_t value, return a structured time stamp.
This change is only visible to components using Rtc_session directly.
Fixes#1381.
