44ddb31e75 Remove some <sys/cdefs.h> cruft.
In particular, we don't need to record the peculiarities of every
version of GCC ever shipped. It just makes this file harder to follow.

f8a2243ebe <netinet/udp.h> should include <linux/udp.h>.
The comment about "other stuff" referred to pre-uapi headers. Everything
in the current <linux/udp.h> should be exposed to userspace. The only
problem is that BSD and Linux use different names for the members of
struct udphdr. We can move the Linux udphdr out of the way and use an
anonymous union to get the best of both worlds. (Though unfortunately
this means that code that includes <linux/udp.h> directly instead of
using <netinet/udp.h> now won't have any definition of struct udphdr.
We've taken the stance in the past that you shouldn't include a linux/
header if there's a standard equivalent --- you should rely on us
transitively including it for you.)

d75abb9614 Fix SOCK_* flag definitions
MIPS and the rest of the world only disagree on the first two SOCK_*
constants, so restructure the #ifdef accordingly.

As a deliberate side effect, this fixes SOCK_DCCP being missing on
non-MIPS platforms.

6048173b36 Import scsi headers.
Linux's scsi headers are a mix of userspace-facing and kernel-facing
declarations that can't be directly used by userspace.  The glibc
maintainers manually copy-and-pasted these definitions into their own
scsi headers and haven't substantially updated them in 15 years.  musl
has a similar set of definitions in its scsi headers.

This change generates the scsi headers from external/kernel-headers,
using the updated generation script so that the single modified scsi.h
takes the place of the non-modified one.

Christopher Ferris
d12c332018 Add support for manually modified kernel headers.
This changes the scripts so that if some kernel files exists
in external/kernel-headers/modified, that they will be preferred
over the same files found in original. This is to support the case
where the kernel headers cannot be taken without some small modifications.

Included with this change, is a general cleanup of the python scripts.

This also modifies the generate uapi headers script to indicate if the
source of the modified headers has changed.

7fda8d2aa4 Implement setjmp cookies on ARM.
Reuse the top bits of _JB_SIGFLAG field previously used to store a
boolean to store a cookie that's validated by [sig]longjmp to make it
harder to use as a ROP gadget. Additionally, encrypt saved registers
with the cookie so that an attacker can't modify a register's value to
a specific value without knowing the cookie.

569333293a Fix the way to get main thread stack start address.
For previous way to get the stack using the [stack] string from
/proc/self/task/<pid>/maps is not enough. On x86/x86_64, if an
alternative signal stack is used while a task switch happens,
the [stack] indicator may no longer be correct.

Instead, stack_start from /proc/self/stat which is always inside
the main stack, is used to find the main stack in /proc/self/maps.

efc134dba3 Only close stdin/stdout/stderr for debug malloc.
The debug malloc code unconditionally closes stdin/stdout/stderr,
which means that other atexit functions cannot use them. Only
close these if there is a debug malloc final function to call.

This doesn't appear to be a problem on most normal applications or the
atexit_exit bionic unit test would be failing. However, if you
enable stat dumping in jemalloc, nothing prints. Most likely trying
to add an atexit function from within libc is causing that atexit
to run after the debug malloc atexit function.

32bf43f44a Rename debug_stacktrace to debug_backtrace.
All the functions say "backtrace", so it's weird that the filename

adf5c7237d Fix regoff_t for LP32 and _FILE_OFFSET_BITS=64.
bionic is built without _FILE_OFFSET_BITS=64, so internally regoff_t
was 32-bit on LP32, but code compiled with _FILE_OFFSET_BITS would
expect rm_so and rm_eo in struct regmatch_t to be 64-bit, leading to
confusion.

ac77536b79 Move tzdata scripts from bionic to external/icu
The scripts affect files in external/icu, bionic
and the generated files affect libcore. The files must
be updated together so there is no "obvious" home.

OEM developers seem to want to update ICU
themselves and have been asking how. Moving the
scripts to external/icu and splitting the ICU generation
code into a sub-script they can run makes some sense.
