c20de90287 Remove ALIGNBYTES and ALIGN from <sys/param.h>
There are only three users of bionic definition of ALIGN and keeping it
in sys/param.h polutes the namespace.

I inline the definition in the the three places that's used.

cccfe1e17c Reimplement clock(3) and switch to OpenBSD time(3).
The new implementation is a better approximation to the processor time used
by the process because it's actually based on resource usage rather than just
elapsed wall clock time.

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

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).

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.

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.

c835c35727 Add some more headers.
This patch adds trivial implementations of the missing sys headers
needed by strace. All strace needs are the constants and structures,
so this is enough for now. We can come back and add the functions
if/when we ever need them.

0f461e35f6 Fix <sys/resource.h>.
The situation here is a bit confusing. On 64-bit, rlimit and rlimit64 are
the same, and so getrlimit/getrlimit64, setrlimit/setrlimit64,
and prlimit/prlimit64 are all the same. On 32-bit, rlimit and rlimit64 are
different. 32-bit architectures other than MIPS go one step further by having
an even more limited getrlimit system call, so arm and x86 need to use
ugetrlimit instead of getrlimit. Worse, the 32-bit architectures don't have
64-bit getrlimit- and setrlimit-equivalent system calls, and you have to use
prlimit64 instead. There's no 32-bit prlimit system call, so there's no
easy implementation of that --- what should we do if the result of prlimit64
won't fit in a struct rlimit? Since 32-bit survived without prlimit/prlimit64
for this long, I'm not going to bother implementing prlimit for 32-bit.

We need the rlimit64 functions to be able to build strace 4.8 out of the box.

c13fb75cea Move bionic over to GCC's 'warning' attribute.
This is a better solution than the old __warn_references because it's
a compile-time rather than link-time warning, it doesn't rely on something
that doesn't appear to be supported by gold (which is why you only used
to see these warnings on mips builds), and the errors refer to the exact
call site(s) rather than just telling you which object file contains a
reference to the bad function.

This is primarily so we can build bionic for aarch64; building libc.so
caused these warnings to fire (because link time is the wrong time) and
warnings are errors.

ed45970ac5 Add cfi directives to all arm assembly.
Since the ENTRY/END macros now have .cfi_startproc/.cfi_endproc, most of the
custom arm assembly has no unwind information. Adding the proper cfi directives
for these and removing the arm directives.

Update the gensyscalls.py script to add these cfi directives for the generated
assembly. Also fix the references to non-uapi headers to the proper uapi
header.

In addition, remove the kill.S, tkill.S, tgkill.S for arm since they are not
needed at all. The unwinder (libunwind) is able to properly unwind using the
normal abort.

After this change, I can unwind through the system calls again.
