[MIPS] Add Real Time Signal Functions and minor bug fixes.
1. Added:
rt_sigaction(),
rt_sigprocmask(), and
rt_sigtimedwait portable syscalls.
2. Fixed a bug in signal.c.
3. Added a new pair of functions to map siginfo_t
between portable and native formats.
4. Fixed LTP rt_siqqueueinfo01 and siqqueue() test failures.
5. Using these new siginfo_t mapping functions in functions
that were previously doing this functionality internally:
a. mips_sigaction_handler()
b. __rt_sigtimedwait_portable()
6. Modified rt_sigqueueinfo_portable():
a. Added a call to this new siginfo_pton() function.
b. Fixed native_sig calculation; it was converting
with the wrong function (ntop instead of pton).
7. Added the Thread Group Flavor of Real Time version of
sigqueueinfo().
8. Added and tested the sigqueue() implementation thought it's
not supported by Android yet. Using a LTP library function
to implement it via syscall for now. Android has a
sysconf() regression that will be addressed in a separate
commit.
9. Modified some of the variable names in:
__rt_sigtimedwait_portable()
to make it easier/faster to read.
10. Fixed a SIGTERM --> SIGTERM_PORTABLE mapping bug.
Most LTP Posix sigqueue() tests and the rt_sigqueueinfo01() test
now pass with this commit.
