430527b4cd Update the generate script.
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.

bb9fcb4636 Update to v5.6 kernel headers.
Kernel headers coming from:

Git: https://android.googlesource.com/kernel/common/
Branch: android-mainline
Tag: android-mainline-5.6

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.

1cc755c8cf Fully disable clang format where needed.
Even with formatting off, clang still tries to rearrange the include
files or the using statements, so disable that too.

09e77f35ab _FILE_OFFSET_BITS=64 support for fcntl.
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/.)

fdaf82f96b Link .clang-format file to system/core one.
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.

9584fa46e9 Update to android-mainline kernel headers v5.4.
Update generate_uapi_headers.sh to checkout the android mainline
kernel. Also, add a small modification to look for the kernel directory

Remove deprecated android headers from android/uapi/linux. Also,
remove f_accessory.h since it's in the android mainline kernel.

6d6b4cedd1 clean_header: Fix error handling for no-such-file case
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>

bb4cf7b8a7 clean_header: Don't print extraneous newline char
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.

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.

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)

658b16fd90 Rewrite removeVarsAndFuncs.
The current version has these bugs:
- Adding a semicolon after a function results in the removal of structures
  following the function.
- Function like macros get removed on accident rather than on purpose.
- It removes extern "C" { completely, which might not be a bug, but doesn't
  seem right.

I couldn't easily fix any of these problems because the code depends heavily
on the header being correct.

New unit tests added for the function to cover all of these cases.

A follow-on CL will include the updated headers.

Bug: 112290385

Test: Passes all new unit tests.
Test: When run on the current kernel headers, the generated headers are

f2484aaed7 Fix handling of #elif.
When a construct like:

if defined(something)
  blocks1
elif 1
  blocks2
else
  blocks3
endif

The parser would put the first clause but then simply omit the elif and
put all of blocks2 without a terminating #endif. The code also did
something similar when the #else was an #endif.

Also convert all of the unit tests to real unit tests and only run
them if you run cpp.py by itself. Added new unit tests to cover the
new cases.

64f355ffbd Use in_addr in ip_mreq_source and ip_msfilter.
This adds a new mechanism to say "replace struct S with #include <bits/S.h>".

Also switch epoll_event over to the new mechanism.

Also use the kernel's struct sockaddr_storage directly rather than behind
an unnecessary #define.

This patch also removes some dead code in the header scrubber. This code
still needs rewriting completely. I learned that a "block" isn't necessarily
a single struct definition, say; it might be a run of them. It seems like
a block is a run of preprocessor directives or a run of regular code.
