df85f50b82 Add an obvious comment to <stdio.h> for fixincludes.
We don't want GCC's fixincludes to touch our <stdio.h> because we
want to support multiple platform versions with one toolchain. Give
them a nice easy unambiguous string to look for.

b6cc8e00cd Fix mbsrtowcs(3) src param for finished string.
A mistake I made while cleaning this up the first time through.
mbstrtowcs(3) sets the src param to null if it finishes the string.

1aec7c1a35 Proper MB_CUR_MAX.
Previously this was hard coded to 4. This is only the case for UTF-8
locales.

As a side effect, this properly reports C.UTF-8 as the default locale
instead of C.

Christopher Ferris
e03e1eac0b Fix memchr with a zero length.
The memchr implementation for 64 bit fails if these conditions occur:

- The buffer is 32 byte aligned.
- The buffer contains the character in the first byte.
- The count sent in is zero.

The function should return NULL, but it's not.

Christopher Ferris
861c0ef37b Use libunwindbacktrace for debug malloc code.
Create a method of disabling the debug allocation code paths so that
it's possible to use the libunwindbacktrace library without any
modifications.

Use this path to create and destroy the maps for the process. It's not
stricly necessary in the init code since the symbols are not modified
until after the initialize calls.

Also, remove the debug_XXX source files that doesn't need to be in libc.so.

Fix the maps reading code since it was completely broken for 64 bit.

a406ee6d5f Added a bionic systrace class and tracing to pthread_mutex.cpp.
bionic_systrace.h contains an implementation of tracing that
can be used with systrace.py and its associated viewer.  pthread_mutex
now uses this tracing to track pthread_mutex contention, which can be
enabled by using the "bionic" command line option to systrace.

3e424d0a24 Implement twalk(3), add unit tests.
I've also added insque(3) and remque(3) (from NetBSD because the OpenBSD
ones are currently broken for non-circular lists).

I've not added the three hash table functions that should be in this header
because they operate on a single global hash table and thus aren't likely
to be useful.

bc5a3ec6df [MIPSR6] Use C-coded string ops on mips32r6/mips64r6
The existing assembler code uses deprecated lwl/lwr/swl/swr ops.
Replacing those with misalignment-forgiving lw/sw ops may
involve careful performance tuning.

21972b61ec syscall(3)'s return type should be long.
This doesn't require us to change any of the syscall implementations
because (a) the LP32 ones have sizeof(int) == sizeof(long) anyway,
which is how we never noticed this bug before and (b) the LP64 ones
all use a 64-bit register for the result (and for the syscall number
too).

f1e83cc34a Use vsnprintf(3) in syslog(3).
It seemed like a clever trick to use the internal log message formatting
code in syslog(3), but on reflection that means you can't (for example)
format floating point numbers. This patch switches us over to using good
old vsnprintf(3), even though that requires us to jump through a few hoops.

There's no obvious way to unit test this, so I wrote a little program and
ran that.

dd37251c47 [MIPSR6] setjmp supports mips32r6 and FP64A/FPXX reg models
Save and restore floating point registers via 64-bit
load/stores when possible.  Use assembler's builtin macro
ops to generate pairs of 32-bit load/stores on Mips I cpus.

Some cpus or FR modes have only 16 even-numbered dp fp regs.
This is exposed by _MIPS_FPSET, defined by existing compilers.
