Benchmarks on bullhead-userdebug show that there is a negligent
performance impact when using sparse entries on a 30% loaded
sparse type of 1000 resources.

Use Google3 naming style to match new
projects' and open source google projects' style.
Preferred to do this in a massive CL so as to avoid
style inconsistencies that plague legacy code bases.
This is a relatively NEW code base, may as well keep
it up to date.
Test: name/style refactor - existing tests pass

Previously the way to name resources in tests was to use reference
notation (@[package:][type/]name). Now we use name notation (no @).

For legacy reasons, we kept around the use of UTF-16 internally
in AAPT2. We don't need this and this CL removes all instances of
std::u16string and StringPiece16. The only places still needed
are when interacting with the ResTable APIs that only operate in
UTF16.

When an app specifies (or imports) resources with various
configurations for different SDK versions, specifying
a minSdk will make many of those resources unreachable.
Version collapsing will prune out the resources specified
for SDK versions less than the minSdk.
If, however, there is no exact matching resource for the
minSdk version, the next smallest SDK version is kept.

Without needing to conform to the runtime data format,
it is much easier to add new features such as debugging symbols
and carrying over product data to link time.
This also simplifies the runtime format parser and serializer,
which will change much less frequently than the protobuf intermediate
format.

Integers are now checked to see if they fall in the range
of min/max for the attribute they are assigned.

An early refactor. Some ideas became clearer as
development continued. Now the various phases are much
clearer and more easily reusable.
Also added a ton of tests!
