- posix/Makefile.am, posix/preinstall.am,
posix/include/rtems/posix/timer.h, score/src/objectget.c: Split POSIX
Timer implementation into multiple files. Add obvious error checks
for NULL parameters. Attempt to reduce include files.
- posix/src/timercreate.c, posix/src/timerdelete.c,
posix/src/timergetoverrun.c, posix/src/timergettime.c,
posix/src/timerinserthelper.c, posix/src/timersettime.c,
posix/src/timertsr.c: New files.
- posix/src/ptimer1.c: Removed.
