Log Message: ----------- [libknet] allow better handling of internal threads

while playing around adding some dynamic internal threads, i did hit a limitation with allocating a dynamic THREAD_MAX value based on OS availability of certain features.

this patch changes from dynamic to static allocation of threads, that can always be increased if necessary without breaking anything.

simplify thread numbering and conditionals on OS features

improve debugging of thread status by adding a 2 phase thread registration process:

- register a thread before starting it with THREAD_STARTING - register a thread as started with THREAD_STARTED

any failure in between can now be detected in debugging logs.

Note for developers: all threads *MUST* be registered/started before wait_all_threads_status check in handle.c.
