The kernel version of the stat structure is used during the syscalls. After the syscall,
the kernel stat structure is converted to match the generic one. Eventually we would like
the generic stat structure and related syscalls be added to MIPS64 kernel, removing the
thunks added to AOSP.

This text is actually in POSIX (though it's not mandatory) and it's what glibc
says. Who says "file number" anyway?

Several cache related queries are added, such as
_SC_LEVEL1_DCACHE_LINESIZE, _SC_LEVEL1_DCACHE_SIZE and etc. For the
moment, we always return 0 for these queries.

On LP32, this makes no difference. Not an ABI change.
On LP64, results are going to be in %rax or x0 whether they're 32- or 64-bit,
and the only difference is going to be whether the top bits are clobbered.

Our representation of sub-second times matched the Linux kernel, and we
provided macros for glibc source compatibility. This change switches us
over to match POSIX 2008, adds the macros they insist on (for compatibility
with earlier versions of POSIX), and also adds macros for compatibility
with any code that expects the kernel or old bionic names.
Unfortunately this breaks strace which defines its own structures using
the kernel names, and thus implicitly assumes that there are no macros with
those names, but this does allow the rest of the tree to build.

__open_2() is used by the fortify implementation of open(2) in
fcntl.h, and as such needs an unmangled C name. For some reason
(inlining?), this doesn't cause problems at the default optimization
level, but does for -O0.
The rest of these didn't cause build failures, but they look suspect
and probably will, we just haven't caught them yet.

Otherwise the gcc compiler warning doesn't show up.
Add -Wno-error to fortify related tests. Fortify related tests
are expected to be examples of bad programs, and in many
cases shouldn't compile cleanly. Rewriting them to compile
cleanly isn't feasible nor desirable.

Otherwise the gcc compiler warning doesn't show up.
Delete some unittests. These unittests no longer compile cleanly
using -Wall -Werror, and rewriting them to compile cleanly
isn't feasible.

fpathconf(3) and pathconf(3) can share code. There's no such
header file as <pathconf.h>. glibc/POSIX and BSD disagree about where
the _POSIX_* definitions should go.

This was already present for the other architectures. I think we skipped
this because glibc seems to have an incorrect definition (int rather than
long), but the kernel has the sane definition (just not in a uapi header).

Other changes to support the new headers:
- Remove the flock64 structure it is defined in the new headers.
- Update the syscalls to correspond with the headers.

POSIX also says that ucontext_t's uc_sigmask has type sigset_t.
MIPS64 strace needs this.
The #define is to keep chromium off our lawn; otherwise it tries to redefine
all this stuff itself. We should probably clean that up and remove the #define.

This showed up as open_memstream not being visible in <stdio.h>

GCC assembler allows xyz to be redeclared as weak,
by __weak_alias(xyz, _xyz), while _xyz is undefined.
Clang does not like that but silently generates no code.
It will reject its own .s file if the assembly code is saved first.
Since we have no reason to define xyz or _xyz as weak symbol now,
and _xyz is a macro to xyz, we simplify libC to have only
xyz defined as global.

Also remove declaration.
The only user is compiler-rt, and they can replace that call with one to
syscall(2). compiler-rt doesn't currently build on mips64 anyway.

This way it's a lot harder for us to screw up (since we should always
be including <sys/cdefs.h> anyway).

Fix and use __RENAME (and lose ___RENAME --- two underscores should be
enough for anybody). This was the point of this change, because I want
to use __RENAME to support the two basename variants and the two
strerror_r variants.
Lose a bunch of macros that weren't being used.
Lose three dead files from the DNS code.

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).
