sched/semaphore: Move cancel point and errno handling to libc / user-space
...
This moves all the public POSIX semaphore functions into libc and with
this most of the user-space logic is also moved; namely cancel point and
errno handling.
This also removes the need for the _SEM_XX macros used to differentiate
which API is used per user-/kernel mode. Such macros are henceforth
unnecessary.

sched/semaphore: Remove restriction to use nxsem_trywait from ISR
...
Considering that `nxsem_trywait` is non-blocking, although not
recommended, it could be called from the interrupt handler.

sched/semaphore: sem_trywait() modifies the errno value and, hence, should not be used within the OS. Use nxsem_trywait() instead.

sem_wait() and sem_trywait() no longer modify the errno value UNLESS an error occurs. This allows these functions to be used internallly without clobbering the errno value.
