When the build type changes (for example, from "shamu-userdebug"
to "shamu-user"), the build system doesn't delete all files
and start over. Rather, build artifacts from the old build type
are reused for the new build type.
This is problematic for the recovery SELinux policy, which differs
between build types. Reusing a userdebug policy on a user build
is inappropriate and could lead to security bugs.
Force the deletion of the recovery SELinux policy when changing
build types, so it can be properly regenerated. This is consistent
with how we treat the normal SELinux policy (see commit
a8b3d54101).

And everything special-cased on that. Add a warning if USE_NINJA is
set to let users know that it no longer changes anything.

We may have devices with OEM-specific properties but without an OEM
partition (e.g. the properties might be set by init based on hardware
SKUs). For such devices, we supply --oem_no_mount to skip mounting the
OEM partition in the updater-script. The option is only meaningful when
-o (--oem_settings) is specified.

Modify the compiler flags for Jack and javac.
This has the following effects:
1) Generally, some of the type inference rules changed.
2) javac: bytecode is generated with the v52 major version (not v51)
3) jack: Java 8 language features are supported.
The javac / dx toolchain does not support Java 8 language features.

There are some code policies we want to enforce more strictly, but
it's hard to do so for third party code because we have to either
carry the diff burden or upstream the patch, and in the latter case
the turnaround time for fixes can be problematic, and sometimes
upstream won't accept changes (sometimes people just need to win the
obfuscated C contest).
We define ANDROID_STRICT for any code that we expect to be able to
make these policy fixes as we change policies.

The actual clang compiler called for static analysis is decided
by build/core/binary.mk, not the one given to --use-analyzer.

It's a valid situation for all three of LOCAL_INIT_RC, LOCAL_INIT_RC_32,
and LOCAL_INIT_RC_64 to be used.

Add --downgrade flag to ota_from_target_files.py script. It allows
generating an incremental OTA that updates from a newer build to an
older one (based on timestamp comparison). "post-timestamp" line in the
metadata file will be replaced by "ota-downgrade=yes". A data wipe will
always be enforced, so "ota-wipe=yes" will also be included in the
metadata file.

Sandy Bridge actually doesn't have all of these options. For example AVX is only
available on the higher-end SKUs (not on Celeron G550).

Pass -w dupbuild=err to ninja to make defining multiple rules to build a
file an error instead of a warning. Proceeding with the build would
result in undefined behavior, and nobody notices the warning.

When more than one makefile tries to copy a header to the same
destination, the warning is not clear, and hard to track down and assign
blame:
build/core/copy_headers.mk:15: warning: ignoring old commands for target `out/target/product/bullhead/obj/include/qcom/display/copybit.h'
With this change, the same behavior is kept, but the warning message is
more descriptive, and contains the offending Android.mk files:
build/core/Makefile:54: Duplicate header copy: out/target/product/bullhead/obj/include/qcom/display/copybit.h
build/core/Makefile:54: Defined in: hardware/qcom/display/msm8994/libcopybit/Android.mk hardware/qcom/display/msm8994/libcopybit/Android.mk
In this case, a $(CLEAR_VARS) is missing, so the same Android.mk file is
copying the same headers twice.
