Modify bionic unit tests that are built for glibc so that they also
build against musl. They don't all pass though:
With glibc:
2 SLOW TESTS
4 TIMEOUT TESTS
313 FAILED TESTS
YOU HAVE 2 DISABLED TESTS
With musl:
11 SLOW TESTS
11 TIMEOUT TESTS
363 FAILED TESTS
YOU HAVE 2 DISABLED TESTS

On Android, fcntl is always implemented by fcntl64(2). This means that
an LP32 binary can `fcntl(F_SETLK, struct flock)` (because fcntl64(2)
passes through to the 32-bit fcntl(2) to handle F_SETLK), and it can
also `fcntl(F_SETLK64, struct flock64)`. What it can't do before this
patch is set _FILE_OFFSET_BITS=64 and then `fcntl(F_SETLK, struct
flock)` where that `struct flock` is actually implicitly `struct
flock64`.
Move the kernel uapi structs out of the way, define them ourselves based
on __LP64__ and _FILE_OFFSET_BITS, and fix up the relevant F_ constants.
(Also add a .clang-format to turn off clang-format in libc/include/.)

Previously the test compared /proc/version read into expected[256]
with actual[BUFSIZ]. This CL aligns the both of the buffer sizes to
the same BUFSIZ, so that /proc/version longer than 256 bytes won't
result in a test failure.

Strictly, the mode isn't really meaningful unless you supply O_EXCL,
but the kernel will take it and fstat will return it even if you
never give the file a name.
Also warn for O_TMPFILE without a mode at compile time where possible.

Test fcntl#falloc_punch is wrong. It checks that fallocate() with mode
FALLOC_FL_PUNCH_HOLE fails on ext4 file system on older kernels. The
test fails to ensure that the file it creates is indeed on an ext4
partition. On an Angelfish device for example, the file is created on an
f2fs partition, which supports FALLOC_FL_PUNCH_HOLE, and thus the test
fails (wrongly).

I've also switched some tests to be positive rather than negative,
because !defined is slightly harder to reason about and there are
only two cases: bionic and glibc.

On LP64 systems F_GETLK64, F_SETLK64 and F_SETLKW64 definitions should
map onto the F_GETLK, F_SETLK and F_SETLKW definitions, respectively.
LP64 also doesn't have a struct flock64.

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).

In practice, thanks to all the registers the stubs don't actually change,
but it's confusing to have an incorrect declaration.
I suspect that fcntl remains broken for aarch64; it happens to work for
x86_64 because the first vararg argument gets placed in the right register
anyway, but I have no reason to believe that's true for aarch64.
This patch adds a unit test, though, so we'll be able to tell when we get
as far as running the unit tests.
