This makes the signapk tool use Conscrypt (where possible) instead of
the platform-default JCA providers and the Bouncy Castle JCA provider.
This speeds up (by 10-30%) APK and OTA update signing because
Conscrypt's crypto primitives are backed by BoringSSL.
Previously, the signapk tool consisted only of the signapk.jar.
Because Conscrypt is backed by native code, signapk now consists of
signapk.jar and crypto_openjdk_jni shared library. This requires that
users of the tool be updated to provide a suitable -Djava.library.path
argument to the Java runtime. This change updates all known users of
the tool inside the Android source tree to do so.

This makes signapk align uncompressed .so entries to memory page
boundary (4096 bytes) to enable such libraries to be loaded at runtime
through memory-mapping the APK.
With this change in place, there should no longer be a need to run
zipalign after (or before) signapk.

We used to silently ignore the return value from apply_patch() even if
it had failed. It gives us more trouble to investigate the failure when
the affected file/partition gets touched in subsequent OTAs. This CL
adds the checking of the return value and aborts the update accordingly.

Add an option "--log_diff <filename>" to ota_from_target_files.py
script. When enabled, it logs the differences between the source
and target builds into <filename> when generating incremental OTAs.
Also move target_files_diff.py into releasetools/ so that it can be
packed into otatools.zip.

For some reason ijar won't build against libc++ for TARGET_BUILD_APPS
builds, but does build with libstdc++.

The same optimization was done for binaries in
https://android-review.googlesource.com/#/c/175250/
To create a TOC file from .jar files, this change introduces
ijar, which is designed for this purpose. Only #include lines
were modified from the original version.

Performance:
$ m && touch
frameworks/base/core/java/com/google/android/util/Procedure.java && time
m
Before: 4m30s (1580 targets)
After: 3m57s (772 targets)
Unfortunately, the improvement is small yet, but local
experiments showed we can cut ~2 more minutes if the similar
optimization is done for .dex files.
