GCC tells us everything we need to know. clang does its usual half-assed job.

db68e56997 Brings LC_* defs into line with POSIX
POSIX requires that LC_* constants be defined as macros, and libc++ is testing
for this. Source: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/locale.h.html

779585fb26 Changes our ctype identifiers to match the BSDs
This is to make it possible to adopt the BSDs' implementations for a few locale
APIs in libc++ rather than writing our own, nearly identical, code.

183ad9df53 Allow sharing the RELRO section via a file.
Add flags and a file descriptor to android_dlopen_ext() to allow writing
the RELRO section of the loaded library to a file after relocation
processing, and to allow mapping identical pages from the file over the
top of relocated memory in another process. Explicitly comparing the
pages is required in case a page contains a reference to a symbol
defined in another library loaded at a random base address.

12bbb91645 Support loading libraries to a reserved address.
Add flags and parameters to android_dlopen_ext() to allow loading a
library at an already-reserved fixed address. If the library to be
loaded will not fit within the space reserved, then the linker will
either fail, or allocate its own address space as usual, according to
which flag has been specified. This behaviour only applies to the
specific library requested; any other libraries loaded as dependencies
will be loaded in the normal fashion.

There is a new gtest included to cover the functionality added.

012cb4583a Add android_dlopen_ext() interface to linker.
Add a function "android_dlopen_ext()", defined in <android/dlext.h>.
This is an extended version of dlopen() which takes a struct for passing
additional parameters for Android-specific functionality. This will be
used to support RELRO section sharing between separate processes.

205c7887ad Clean up reentrancy cruft.
The DNS copy of reentrant.h was unused, so remove it.

The strtod implementation can use the upstream-netbsd reentrant.h and
get a little closer to what was then upstream. (It's since been replaced
by gdtoa, and we'll have to follow at some point, but for now this doesn't
make anything any worse.)

ANDROID_CHANGES is (now) only used in the DNS code, so push the -D
down.

The <locale.h> change prevents an LP32 hack from leaking into LP64.

c9ae21a5c3 Move system_properties over to C++.
This change constitutes the minimum amount of
work required to move the code over to C++, address
compiler warnings, and to make it const correct and
idiomatic (within the constraints of being called
from C code).

Also undo some of the mess where we have OpenBSD <stdio.h> but a mix of
different BSD's implementations.

In this first pass, I've only moved easy OpenBSD stuff.

db1ea34748 Implement some of the missing LFS64 support.
This gives us:

* <dirent.h>
  struct dirent64
  readdir64, readdir64_r, alphasort64, scandir64

* <fcntl.h>
  creat64, openat64, open64.

* <sys/stat.h>
  struct stat64
  fstat64, fstatat64, lstat64, stat64.

* <sys/statvfs.h>
  struct statvfs64
  statvfs64, fstatvfs64.

* <sys/vfs.h>
  struct statfs64
  statfs64, fstatfs64.

This also removes some of the incorrect #define hacks we've had in the
past (for stat64, for example, which we promised to clean up way back
in bug 8472078).

mksh is using this, and we probably build as much BSD source as glibc source.

aa0ebdafc7 Clean up sys_signame and sys_siglist a little.
We don't need quite so much duplication because we already have a way
to get the signal number from its name, and that already copes with the
fact that the mips/mips64 numbers are different from everyone else's.

Also remove sys_signame from LP64. glibc doesn't have this BSD-ism.

199346a2ab Fix NSIG.
Our sigset_t definition hasn't been tied to our NSIG definition since we
switched to uapi headers, so we can now fix it without breaking the LP32 ABI.
The kernel uapi headers define and use _NSIG, so we need to have our scripts
rename the kernel's definitions out of the way, then we can define _NSIG
and NSIG in terms of the kernel's off-by-one value.

old versions of GCC.

0266ae5f88 Switch <elf.h> over to linux uapi under the covers.
Remove the linker's reliance on BSD cruft and use the glibc-style
ElfW macro. (Other code too, but the linker contains the majority
of the code that needs to work for Elf32 and Elf64.)

All platforms need dl_iterate_phdr_static, so it doesn't make sense
to have that part of the per-architecture configuration.

9afe2884c7 Kill <machine/_types.h>.
Most of <machine/_types.h> was either unused, wrong, or identical across
all 32-/64-bit architectures.

I'm not a huge fan of <sys/_types.h> either, but moving the bits we need
up into there is a step forward.

8d60cc6316 Use __inline__ for fortify.
libunwind has #define inline /* empty */ which breaks our fortified headers.
glibc uses __inline but our BSD-derived headers often override that. __inline__
is the third alternative understood by GCC that -- as far as I know -- neither
the C library itself nor third-party code tries to mess with.
