This tool is useful to compare headers between Bionic and NDK platforms.
It shows a summary list of non-equal headers and writes diff report to file.
See 'ndk/tools/headers-diff-bionic-vs-ndk.py --help' for details.

2. elf.h is seen to be included alone, causing compilation error due
to undefined uint32_t and uint64_t

File arch-mips/sigsetjmp.S includes <asm-generic/portability.h>

passes LOCAL_CFLAGS for building *.S as well, but no more >=JB.
Use LOCAL_C_INCLUDES instead (pass for *.S too)

Developers report that concurrent events generated from different
sources/devices can lead to application freezes then ANRs.
See https://code.google.com/p/android/issues/detail?id=41755
where it is suggested that handling all incoming events in
the "process_input" callback solves the issue. Hence this patch
implements the suggestion, however it's unclear whether this
solves the symptom, or the root cause of the problem.

errno in MIPS is macro for "*__errno)()". Use of errno inside
WRAP(__errno)() cause infinite loop. This may happen in other
wrapper functions which access errno.
Change all error to *REAL(__error)()

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.

ARM expanse some functions to others. For example,
_Unwind_GetIP will be inlined to _Unwind_GetGR, which
will be inlined to _Unwind_VRS_Get. This happens at
header-included level.
However, we use Itanium _Unwind_* header as portable one.
We do the inlining in ARM libportable to prevent
undefined reference to these functions.

mmap_portable() was calling madvise() and disrupting errno.
The call to madvise() has been dropped in bionic's version of
mmap() and now we just call that.
Updated helper functions to use the newer <class>_pton() style.
Added logging calls; like the rest of Lib-Portable,
it frequently helps save time.

The portable (ARM) jmp_buf and sigjmp_buf structures are smaller than the native
(MIPS) structures so it is not safe to simply call the standard bionic routines.
Luckily there is a lot of redundant space in the standard MIPS structures
and it is possible to save all of the needed registers in the area provided by the
ARM application.

Improved Logging, tweaked func names, fixed double mappings
of mips_command.
While debugging the LTP fcntl07* set of failures I modified
a few ALOGV() calls to make logging more helpful in
fcntl_cmd_pton().

Both MIPS and ARM use signals 32 to 64 for real-time signals.
ARM signals 32 to 64 can't be masked due to the signal
mask being limited to 32 bits. MIPS signals 32 to 64 can be
masked, and Lib-Portable correctly supports this feature.
Fixes LTP tests rt_sigaction01 and ptrace05.
Fixed a few signal problems; Ex last Real Time Signal
1. The signal handler for signal number 64, the last real
time signal, wasn't being intercepted. Now catching
signal number 64.
2. sigaction() to only change *oldact when return
value is zero.
3. Fixed rt_sigqueue_portable() to set errno when
returning a -1.
4. Fixed a few cases where signal 0 was being added
to the table of signal handlers for signal remapping.
Harmless but a bit silly.

Specifically these functions are now supported:
signalfd4(), eventfd(), timerfd_create(),
pipe(), and inotify_init1()
Modified syscall_portable() to call signalfd4_portable(),
eventfd_portable(), eventfd2_portable(), and timerfd_create().
These system calls enable the read system calls to access
kernel data structures.
The signalfd4() enables read to return a signalfd_siginfo structure
which have the signal number and errno mapped until an execve().
This is similar to the maintaining a table of signal handlers to
map the signal numbers done earlier. This mapping is extended to
the process after an execve() by passing the final set of mapped
file descriptors via a pair of environment variables.
Disabling signal and file descriptor read mapping in parent
if the child would break the mapping algorithms.
This code passes at least all of the non-POSIX LTP tests,
including an updated LTP signalfd4 test that posts SIGNALS
and uses this read() mechanism to get signal info.
inotify_init1 is similar to signalfd(), timerfd() and other
filefd functions which map read() calls. Unlike signalfd(), and
similar to timerfd(), the reads don't appear to need to be mapped.
The members of the inotify_event structure appear to be generic.
The mask bits like IN_MOVE_FROM and IN_MOVE_TO are defined in
generic files. The LTP test in testcases/kernel/syscalls/inotify
test for the inotify_event structure being inotify_event structure
being read and does seem to check it contents being correct.

Just mapping struct addrinfo socktype member; everything else is
identical in ARM vs MIPS cpp comparison.
Lots of tests in getaddrinfo_01 fail on Android, but test 9 and 20
were breaking with lib-portable only. This fix corrects that
difference in the test results.

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.
