The register keyword was already deprecated with C++11, but
with C++17 it has been entirely removed.

_log/_vlog were always called so we always had a function call hit even
if we're not debugging. Expand on the debugging macros so the decision
to call _log/_vlog is done in the caller already. Also, make a log level
difference between syscall_printf and system_printf.

The current implementation is a very simple approach to implement
a statically sized sleep queue. The problem is that this code requires
a certain amount of synchronization because the slots in the queue are
used dynamically. To top it off, the Event objects used for sync'ing
are created and destroyed on demand. This is complicated, slow, and
error prone.
There's also a blatant bug here: The number of slots in the queue was
wrongly computed in size. It was too small if XSI IPC was used a lot.
Make the code more robust. Let the queue have the right size. Every
slot is now used for a specific IPC object. All sync objects (switched
to Semaphores) are only created when first required, but never destroyed.
This reduces the usage of a critical section to the creation of a new
sync object.
