When __memset_chk_fail moved to C++, we didn't take into account
that the stack wasn't set up correctly for the jump from assembler.
Presumably no one had run the 32-bit x86 tests until now!

clang doesn't support attribute alloc_size, but GCC uses it to give
diagnostics where clang can't, and we had a test for one such case.

__STDC_VERSION__ isn't defined for __cplusplus, so we've been removing
such checks. Some got missed.
Stop defining __func__ and just use the __PRETTY_FUNCTION__ GCC extension
in <assert.h>. Also fix the #if there so that C++ gets __assert2 rather
than __assert, and rewrite the cast to work with -I rather than -isystem.
Also remove __restrict and just always use the __restrict GCC extension.
Add a trivial test for <assert.h>.

Test: ran bionic unit tests.
I made a mistake caught by code review earlier, so let's try to be
safer by default.
This patch also moves all our "forwarding" headers to the guardless
just-include-the-other-thing style that we usually use. (Where we
have a comment explaining where the header comes from, I've kept
that.)

Don't use the same declaration to declare both static and non-static
functions, to make life easier for versioner.
(Also, remove __BIONIC_LEGACY_INLINE from two functions in termios.h
that weren't actually legacy inlines.)

Various things:
* work around -Wnullability-completeness.
* use C++ casts in C++ and C casts in C.
* stop using attributes clang doesn't support (such as `warning`).
* remove duplicate definitions of XATTR_CREATE and XATTR_REPLACE.

Modify the generate script to add a new option and copy the types.h
arm header file since it's not currently being created properly. Also
manually generate the arm types.h uapi header since it's not being
properly generated right now.
Modify both generate scripts to delete the target directories before
adding the files to handle moved/deleted header files.
Move the common/scsi headers into android and delete the common
directory. Change the scripts to reflect this change.
Update the scsi headers since they've been modified in upstream kernels.

POSIX and Java disagree about the sign in a timezone string like "GMT+3".
This means that if you set "persist.sys.timezone" to such a string, native
code and Java code disagree about what time it is. Resolve this by
translating to POSIX form for native code.

Test: manually tested with setprop and date.
This change implements the following property:
Any 2**N aligned memory region on size 2**N contains no more than one DSO.
The value N can be configured, with 16 or 18 looking like a good choice.
Additionally, DSOs are loaded at random page-aligned address inside these large
regions.
This change has dual purpose:
1. Larger values of N allow a lot more compact CFI shadow implementation.
See change I14dfea630de468eb5620e7f55f92b1397ba06217.
For example, CFI shadow for the system_server process has the following size (RSS, KB):
152 for N = 12, 32 for N = 16, 16 for N = 18.
2. Extra randomization is good for security.
This change does not result in extra RAM usage, because everything is still page-aligned.
It does result in a bit more VM fragmentation because of the gaps between shared libraries.
As it turns out, this fragmentation is barely noticeable because the kernel creates new mapping
at the highest possible address, and we do enough small mappings to almost completely fill the
gaps (ex. in the Zygote the gaps are filled with .ttf file mappings and thread stacks).
I've measured VM fragmentation as the sum of all VM gaps (unmapped regions) that are larger
than 1MB according to /proc/$PID/maps. On aosp_angler-userdebug, the numbers are (in GB):
| N = 12 | N = 18
system_server | 521.9 | 521.1
zygote64 | 522.1 | 521.3
zygote32 | 2.55 | 2.55
mediaserver | 4.00 | 4.00

We have much better control over visibility now, so we don't need to
pollute the headers with cruft.

Move all of the uapi kernel headers that are only found in the android
kernel, and are still used by the tree into their own directory.
Delete all of these files that are not used.
Also, delete binder.h from the linux directory since it already exists
in the linux/android directory.

gnustl is using this. It would be easy to change gnustl to *not* use
it for Android, but we've had this in released NDKs for years now so
we probably need this anyway.

Soong is always on now, so we don't have to distinguish between
makefiles that should be ignored because Soong is handling them with an
Android.bp file, and makefiles that are still needed with Soong. All
obsolete Android.mk files have been removed, rename all Android.soong.mk
files to Android.mk.
