Bionic currently renames the kernel's __kernel_sockaddr_storage
to sockaddr_storage. We would like to reuse the bionic kernel
headers for musl, but musl defines its own sockaddr_storage,
causing redefinition errors when the musl and kernel headers
are both included.
Give bionic its own definition of sockaddr_storage so the kernel
one can be left as __kernel_sockaddr_storage, avoiding the
conflict in musl.
Some of the structs in netinet/in.h contain sockaddr_storage members.
There are definitions in linux/in.h, but they now use the
__kernel_sockaddr_storage naming. To avoid having to copy the structs
from linux/in.h into netinet/in.h, add some #define hackery to
rename __kernel_sockaddr_storage to sockaddr_storage when including
linux/in.h from netinet/in.h.

When replacing structs with bits/ includes, count the number of
opening and closing braces to find the end of the struct.

Also, remove stale .gitignore line.

Test: the files generated the same exact way.

The argument to this is the characters to strip, so `line.strip(line)`
just returns the empty string.

This fixes all of the problems with our kernel scripts, but not
the clang python script problems.
I also removed the updateGitFiles function since that code was
just silently failing any way. I replaced all calls with updateFiles.
Test: Ran script using python2 to verify it still works.
Test: Run script in python3 verifying that it starts to run.

Rather than "whatever people have installed as 'python' on their machine".
I've removed check-symbols.py because that's been broken for years and
we never even noticed, and I'm not sure it's worth fixing.

Add a make distclean for each supported arch before generating headers
and at the end so these files are not left hanging around in the
kernel directory.

Test: Verified this generates the exact same files as before this change.

The arm kvm.h file has been deprecated, so nobody should be including it.
Therefore, remove the hack to copy the file out of the tools directory.
Also, update to remove the arm kvm.h file.
Test: Ran generate and update script and verified only the arm kvm.h
Test: was deleted.
Test: Builds and boots on a walleye.

Add a new method for removing structures. This is to deal with the kernel
headers changing some definitions of timeval to __kernel_old_timeval
and itimerval to __kernel_old_itimerval. Remove the __kernel_old_XX
strutures and change the other structures to the previous definitions.
This only works so long as these structures stay the same, if they
diverge, then a different strategy will need to be implemented.
Test: Booted cuttlefish/walleye.
Test: Ran bionic-unit-tests on cuttlefish/walleye.

These just cause confusion because they often have different
values/layouts, but they're never actually used.

Even with formatting off, clang still tries to rearrange the include
files or the using statements, so disable that too.
Test: Verified that the include directories are not rearranged.

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/.)

Use the .clang-format-2 found in system/core instead of this which is
not actually being used.
Also, enable clang-format running by default.
All upstream directories are marked as ignoring formatting so that
their source files are not modified.
Test: NA

Update generate_uapi_headers.sh to checkout the android mainline
kernel. Also, add a small modification to look for the kernel directory
in common not linux-stable.
Remove deprecated android headers from android/uapi/linux. Also,
remove f_accessory.h since it's in the android mainline kernel.
Test: Builds and runs on walleye.

Also, fix a bug in update_all.py when the syscalls file does not change.

Enable the use case where we run clean_header.py from outside of
$ANDROID_BUILD_TOP. Previously, this script required the current working
directory to be under $ANDROID_BUILD_TOP. Running it from a different
directory resulted in the following error message:
clean_header.py: error: Not in android tree pointed at by ANDROID_BUILD_TOP (....)
Change-Id: I48210ea1a0033228a9aaa4124d28247b07cee6d4
The function cleanupFile should always return a single value (as opposed
to a tuple or list). In addition, if it encounters an error, it is
expected to return a value that evaluates to False. As it stands,
however, it returns (None, None) in certain error cases. Change this
function to return None, in those cases.
We previously saw the following error message, when we tried to run
clean_header.py on a non-existent file.
Traceback (most recent call last):
File "clean_header.py", line 208, in <module>
b.updateGitFiles()
File "utils.py", line 164, in updateGitFiles

Don't print an extraneous newline character at the end of the include
file if clean_header.py is used in the non-update mode. This is
necessary to achieve consistent results in the update and non-update
modes.
Running clean_header in the non-update mode and redirecting the output
to a file should have the same result as using the update mode and have
the script write to the file directly.
Change-Id: I6b176c5365840d66e4499bacd205f1fa77302a2b
Write to correct dst_file when in update mode. This enables use cases
like the following:
../../../bionic/libc/kernel/tools/clean_header.py -k original-kernel-headers/ -d kernel-headers/ -u linux/ion.h
Previously, we had to cd into kernel-headers/ and then run
../../../../bionic/libc/kernel/tools/clean_header.py -k ../original-kernel-headers/ -d . -u linux/ion.h
because the tool didn't allow the relative path to be different from the
destination path.

This includes one manual change:
In the file bionic/libc/kernel/uapi/linux/in.h, the macro IN_BADCLASS
was not definied correctly. Change the macro from:
#define IN_BADCLASS(a) ((((long int) (a)) == 0xffffffff)
to:
#define IN_BADCLASS(a) (((long int) (a)) == (long int)0xffffffff)
This change is being pushed to the upstream kernels.
Test: Builds and boots.
