Move implementation specific parts of tqdata.h, threadq.h and
threadq.inl into new header file threadqimpl.h. The threadq.h contains
now only the application visible API.
Delete tqdata.h.
Move implementation specific parts of pthread.h and pthread.inl into new
header file pthreadimpl.h. The pthread.h contains now only the
application visible API.
Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.

score/include/rtems/score/coremutex.h,
score/include/rtems/score/coresem.h, score/src/coresemseize.c: This
patch addresses issues on implementation of the timeout on the
following POSIX services. Some of these services incorrectly took a
timeout as a relative time. Others would compute a 0 delta to timeout
if the absolute time and the current time were equal and thus
incorrectly block the caller forever. The root of the confusion is
that POSIX specifies that if the timeout is incorrect (e.g. in the
past, is now, or is numerically invalid), that it does not matter if
the call would succeed without blocking. This is in contrast to RTEMS
programming style where all errors are checked before any critical
sections are entered. This fix implemented a more uniform way of
handling POSIX absolute time timeouts.

manipulation routines in the SuperCore. Use them everywhere possible.
This lead to significant cleanup in the API routines and eliminated
some of the same code from the POSIX API. At this point, the
SuperCore keeps time in POSIX timespec format properly from 1970. You
just cannot set it before 1988 in keeping with RTEMS traditional
behavior.
