b5ea78ad47 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.

d6a6c218a3 core/msg_bus: allow to differ between messages form bus and from thread 
Currently it is not possible to check if a message was sent over a bus
or if it was send the usual way using `msg_send()`.

This adds a flag to the `sender_pid` if the message was sent over a bus.
`MAXTHREADS` is currently set to 32, so there is still plenty of room in
the PID space. (`kernel_pid_t` is `int16_t`)

The message type for bus message type is already accessed through a getter
function, so it's just consistent to do the same for sender_pid.

core: Access internal vars via helper funcs

46b89eb723 core/msg_bus: fix shift on 8-bit platforms 
The previous shift would wrap if the compiler defaults to 16 bit words.
Use explicit `unsigned long` integer constants to mitigate that.

The return value was never checked. Hence, this runtime check was rather
pointless. Better assert the correct size during development.

426170b064 Improve naming of thread stacksize/priority constants 
As discussed in #2725, this commit renames a number of stacksize constants to
better convey their intended usage. In addition, constants for thread priority
are given a `THREAD_` prefix. Changes are:

* KERNEL_CONF_STACKSIZE_PRINTF renamed to THREAD_EXTRA_STACKSIZE_PRINTF
* KERNEL_CONF_STACKSIZE_DEFAULT renamed to THREAD_STACKSIZE_DEFAULT
* KERNEL_CONF_STACKSIZE_IDLE renamed to THREAD_STACKSIZE_IDLE
* KERNEL_CONF_STACKSIZE_MAIN renamed to THREAD_STACKSIZE_MAIN
* Move thread stacksizes from kernel.h to thread.h, since the prefix changed
* PRIORITY_MIN renamed to THREAD_PRIORITY_MIN
* PRIORITY_IDLE renamed to THREAD_PRIORITY_IDLE
* PRIORITY_MAIN renamed to THREAD_PRIORITY_MAIN
* Move thread priorities from kernel.h to thread.h since the prefix has changed
* MINIMUM_STACK_SIZE renamed to THREAD_STACKSIZE_MINIMUM for consistency

5f29fed076 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.
