Append .Parallel() to the defaults RegisterTopDownMutator call to tell
Blueprint it can run it in parallel. Saves ~500ms in soong_build.

Disable coverage for static binaries where address sanitizer is
disabled, and disable coverage in the mutator when disabling address
sanitizer.

Change-Id: Ia1a21878c3f34cd295a6dec49608c412eb09e7b1
Append .Parallel() to all of the RegisterBottomUpMutator calls to tell
Blueprint it can run them in parallel.
Test: identical build.ninja, passes race detector

* changes:
Rename soong_jar to soong_zip
soong_jar: Parallel compression
Add zip2zip tool to copy zip entries from one file to another
Add archive/zip from go1.7rc5 tag
This compresses multiple files in parallel, and will split up larger
files (5MB+) into smaller chunks (1MB) to compress in parallel.
There is a small size overhead to recombine the chunks, but it's only a
few bytes per chunk, so for a 1MB chunk, it's minimal.
Rough numbers, with everything in the page cache, this can compress
~4GB (1000 files) down to 1GB in 6.5 seconds, instead of 120 seconds with
the non-parallel soong_jar and 150 seconds with zip.
Go's DEFLATE algorithm is still a bit worse than zip's -- about 3.5%
larger file sizes, but for most of our "dist" targets that is fine.

This doesn't do any decompression / recompression, but just copies over
the already compressed contents. So it's similar to zip -U, but allows
rewriting of the paths.
The first expected usecase is to replace img_from_target_files during
the build, since it does the equivalent of this:
zip2zip -i <target-files.zip> -o <img.zip> OTA/android-info.txt:android-info.txt IMAGES/*:.
Except it decompresses and recompresses the images, which takes over a
minute instead of a few seconds.

In preparation to patch in some custom functionality (parallel
compression and zero-decompress zip to zip copying)

BottomUpMutators are going to lose their ctx.Visit* functions in order
to allow parallelizing them, move defaults to a TopDownMutator using
WalkDeps to only visit defaults modules.
Test: no changes to out/soong/build.ninja

Blueprint can now handle creating a zero-valued struct when it
encounters a nil pointer to a struct, reducing the amount of allocations
and copying for arch structures that are not used.

Didn't catch these the first time because I hadn't done a clean build.
Test: rm -rf out && make ndk

It's better to clip to the existing versions here rather than build
the lower levels as if they existed.
cc.Module's begin() will now normalize the sdk_version to a valid
value for the given architecture so that doesn't have to be checked
later.
Test: make checkbuild with all other libc ndk_library changes

Ensure that we only create one directory entry, not one with a / at the
end and another without. Clean incoming paths to prevent other similar
duplicates.
When adding directories specified directly as inputs, use the relative
path just like files, not the full path.
Instead of traversing symlinks, addg them to the zip file directly.
Present an error instead of crashing when an input does not exist.

For example , instead of trying to have libraryLinker inherit from
baseLinker and libraryCompiler inherit from baseCompiler, create a
single decorator object that wraps both baseLinker and baseCompiler.

We were generating this, but not actually using it yet.
Test: `make ndk` with libc/libm migration patches, readelf generated
libs.
