Linker --wrap option resolves to __wrap_symbol for undefined symbol.
During the compilation of host libportable.a, __HOST__ is defined
to rename all portable functions to __wrap_symbol, and the
real function to __real_symbol. This way libportable.a can be
validated at host w/o changes of user's source code.

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.

Unifying around the <class>_ntop() style;
changing ntop_*() and pton_* to *_ntop() and *_pton().
Also added portable versions of strerror() and strerror_r()
while updating the errno.c file.

File poll.c had a wide line and the reason for the asymmetric
mapping of the event flags wasn't obvious on my reviewing
this code. Seemed to justify adding some clarification.
Both signal.c and socket.c were using lengthy function names
for Portable <--> Native mappings. Switch to the newer *_ntop()
style in wide files and made the ALOGV() messages more useful.
Also changed mapping of portable SIGSTKFLT to native SIGEMT
while editing a wide line in the signal.c file. MIPS has no
SIGSTKFLT signal, nor ARM a signal SIGEMT. Using SIGEMT as a
proxy for SIGSTKFLT_PORTABLE for Lib-Portable applications.
This makes the signal mapping reversible during signal handling.
Fixed ALOGV() Entry/Exit brackets to match.

Signals needed to be mapped.
