Read /proc/stat to count online cpus is not correct for all android
kernels. Change to reading /sys/devices/system/cpu/online instead.

If the OVERRIDE_C_DATE_TIME environment variable is set, the build
system will add a macro to the global cflags that contains a static
quoted date, like:
-D__DATE__="\"Sep 28 2015\""
file-check-cxx needs to properly pass that through as a single, still
quoted argument. So use the quoted "$@" instead of turning each word
into an argument.

Turning on color output will break the bionic compilation tests that
check for expected warnings, as they will be matching color output
against non-color expected values. Turn off color locally.

This bug will happen when these circumstances are met:
- Destination address & 0x7 == 1, strlen of src is 11, 12, 13.
- Destination address & 0x7 == 2, strlen of src is 10, 11, 12.
- Destination address & 0x7 == 3, strlen of src is 9, 10, 11.
- Destination address & 0x7 == 4, strlen of src is 8, 9, 10.
In these cases, the dest alignment code does a ldr which reads 4 bytes,
and it will read past the end of the source. In most cases, this is
probably benign, but if this crosses into a new page it could cause a
crash.
Fix the labels in the cortex-a9 strcat.
Modify the overread test to vary the dst alignment to expost this bug.
Also, shrink the strcat/strlcat overread cases since the dst alignment
variation increases the runtime too much.

The routines optimized for cortex-a7 and cortex-a53 cause performance
drops on cortex-a57. Instead create a target that is the middle ground
that works relatively well on either core.

Unfortunately --exclude-libs (now passed globally) clobbers our
version script, so we have to prevent the build system from using this
flag.

Until we implement full support for passwd/group files, add a simple
way to use the new OEM UID/GID range (5000-5999).
oem_XXX -> 5000 + XXX iff 0 <= XXX < 1000.

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.

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.)

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.

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.

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.
