Names for pthread synchronization objects?

Hello,

all the POSIX synchronization objects use thread queues. Each thread queue
has a name member. It would be nice to have a function to set this name.
Unfortunately there is no POSIX, glibc, FreeBSD or QNX function to do this.
Some IBM OS have a pthread_mutexattr_setname_np(). For threads glibc has a
pthread_setname_np(). We have some options.

1. Offer no function to set the names (not really great for debugging and
system diagnostics).
2. Add *_np() functions to Newlib pthread.h, e.g.
pthread_mutex_setname_np(mtx, name), PTHREAD_MUTEX_NAMED_
INITIALIZER_NP(name).
3. Add an RTEMS-specific header <rtems/pthread.h> with
rtems_pthread_mutex_set_name(), etc. functions.


I lean to #2.
