This results in nearly all functions with the possibility of stack
corruption getting stack canaries, because it applies to any function
taking a reference to the frame or with a local array rather than just
the functions with arrays larger than 8 bytes. It was developed for use
in Chrome (and Chrome OS) and has also been adopted by various other
distributions (Arch, Fedora, Ubuntu, etc).
The code size increase ranges from ~1.5% to ~2.5%, compared to ~0.3% to
~0.7% with the more conservative switch. The increase in the performance
loss is usually minimal. The overall size increase once everything other
than C and C++ code is taken into account is minimal, and it greatly
improves the mitigation of stack buffer overflow vulnerabilities.

Only if an app has LOCAL_INSTRUMENTATION_FOR, it can get the emma
classes from the target app and we don't need to instrument the test app
itself.

For AB builds, add the build type to META/build_type.txt so the
server can easily determine user, userdebug, and eng builds
from each other.

At least one shared object in internal repo doesn't have
SONAME entry in its dynamic segment because it is created by
objcopy instead of a linker.

[Second attempt, this time with updated mac prebuilt]
Switches default linker from -fuse-ld-bfd to
-fuse-ld=gold, and enables -Wl,--icf=safe. This
changes reduces /system/lib64/*.so text size
by about 2% for N9.

getLongLE would return a 64-bit number with the upper 32-bits set when
decoding a 32-bit number with the top bit set. Per the zip file format,
it was only expected to return a 32-bit number. Use explicitly sized
types so that we use the proper sizes and don't do any implicit
extensions.

ziptime fails on zip file larger than 2GB.
These zip files won't installed on device and we don't care that much
about their reprodudcibility across builds.

When a shared object is rebuilt, all dependent libraries and
executables are rebuilt. Such rebuild is unnecessary when there
is no interface change. With this patch, .toc files will be
generated for all .so files. The rule which generates .toc files
has ninja's restat=1 and .toc files are not changed ninja won't
rebuild dependent targets.

ANDROID_GOALS: any Android goals that need to be built.
KATI_GOALS: goals that we need to pass to Kati.
NINJA_GOALS: goals we need to pass to Ninja.
For modifier Android goals (dist, INTERNAL_MODIFIER_TARGETS),
we don't need to pass them to Ninja. See also commit
80e46c7c5c.
Restore the dist rule removed by the above commit.
Previously "droid" was never passed to Ninja. That's incorrect.
"make droid docs" should build both docs and droiod.
Fixed with this change.

* commit 'a63d379aab75fe3991320319f63faddd3b84b287':
Don't check the host JDK tools when build/core/config.mk is called from envsetup.sh.
Envsetup.sh (lunch) relies on config.mk to get build varaible values; while
config.mk may rely on envsetup.sh to set up JAVA_HOME/PATH.
Without this change config.mk may be checking the host JDK tools before
JAVA_HOME/PATH get set up.

Pass -X to zip so that Unix UID/GID and extra timestamps aren't
saved into the zip files.
Add a new tool, ziptime, that uses a very stripped down copy of
zipalign. It no longer depends on libandroidfw, and now rewrites the
timestamps in place instead of making a copy of the zipfile. This should
improve speed and reduce disk requirements, especially with the large
packaging zip files.

Specifically, do not error out if no installable apps are found.
- When creating an archive of all the apps, and if no apps exist
for the target, generate an empty archive file.
- If building for a target with no installable jar(s) or apk(s),
generate an empty package stats file.
The former is just an output artifact. The latter is used
by the upload_pkg_stats.py script which correctly handles
an empty input file.

Pass -X to zip so that Unix UID/GID and extra timestamps aren't
saved into the zip files.
Add a new option to zipalign, -t, to replace all timestamps with static
timestamps (2008 Jan 1 00:00:00). Use this for all non-APK zip files.
APK zip timestamps are set based on the certificate date in SignApk.
