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.

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.

Java resource lists created by globs like "**/*" may include
directories. Ignore them when creating the zip file unless
-d was passed on the command line. Fixes read: is a directory
errors.

Combine the zipWriter and info arguments that are passed into every
function into a single writer class, and make all the functions
methods on the new class.

Add support for compiling java libraries (.jar files with
or without .dex), java binaries (.jar files with a wrapper
script to run them), and java prebuilts (for the SDK .jars)
