core: remove needless test in msg.c
...
`thread.c` initializes a thread with an empty message queue. `cib_put()`
will `return -1` for an empty CIB, so there is no need to test if
`thread->msg_array != NULL`.

core: put more intelligence into queue_msg()
...
Fixes #1942 .
There were two instances were it was not checked the target thread has a
message queue before queuing the message.
This PR centralizes the check into `queue_msg()`.

core: msg_receive should yield
...
If a thread sends blocking, but the target thread is not currently in
receive mode, the sender gets queued. If it has a higher priority it
should run again as soon as the target goes into receiving mode.

core: introduce thread_yield_higher(), yield less
...
Fixes #1708 .
Currently involuntary preemption causes the current thread not only to
yield for a higher prioritized thread, but all other threads of its own
priority class, too.
This PR adds the function `thread_yield_higher()`, which will yield the
current thread in favor of higher prioritized functions, but not for
threads of its own priority class.
Boards now need to implement `thread_yield_higher()` instead of
`thread_yield()`, but `COREIF_NG` boards are not affected in any way.
`thread_yield()` retains its old meaning: yield for every thread that
has the same or a higher priority.
This PR does not touch the occurrences of `thread_yield()` in the periph
drivers, because the author of this PR did not look into the logic of
the various driver implementations.

core: msg: yield after queueing of a message if REPLY_BLOCKED
...
When setting the running task reply_blocked, it is implicitly removed
from the runqueue. But if queueing of a msg is actually successful, the
thread exits msg_send without yielding, continuing to run even if it's
not supposed to.
Nice example of why multiple function exit points lead to weird
errors...

If the sender is reply-blocked, waking it up after its message has been

been delivered.
