core/msg: make msg_avail() return 0 on no queue
...
For the caller there should be no difference if there is no message
in the queue and if there can't be a message in the queue.
The current API works as one would expect if there is a message queue,
but once called from a thread that does not have a message queue
configured, code that does
while (msg_avail())
will end up in an infinite loop.
Remove this foot-gun from the API by making the return value of
msg_avail() independend of the availability of a message queue.

core: assert correct msq queue size on creation
...
The return value was never checked. Hence, this runtime check was rather
pointless. Better assert the correct size during development.

Per default, doxygen will take only the part until the first dot into
account for the brief description. In this case this leads to an
ambiguous overview over the IPC send functions.

core: introduce msg_sent_by_int()
...
msg_send_int() sets `m->sender_pid = target_pid`. This was used to flag a
message as having been sent by an ISR.
This PR introduces a static inline function `msg_sent_by_int()` and a
specific define for this purpose.
