* refactor: ExtDataInput rework, source layout and formatting
Refactor ExtDataInput classes: ExtDataInput is now the extended interface,
ExtDataInputStream is an easy-to-use FilterInputStream implementing ExtDataInput
with static creator methods for big-endian and little-endian wrappers.
Refactor AaptManager class: unify aapt-related verifications to one class.
Replace Apache Commons' deprecated CountingInputStream with Google Guava's
equivalent with the same name. Apache's BoundedInputStream is an overkill
for our use case and its constructors are deprecated as well.
Normalize source layout to have a common and somewhat more standard order:
Static fields first, instance fields after, methods last.
Fix some formatting, like empty spaces or extra spaces and exception messages.
Renamed ResXmlPatcher to ResXmlUtils, as it has more purposes than just patching.
Renamed DirUtil to DirUtils, to match other utility classes naming convention.
Moved "properties/apktool.properties" to jar's root, to match smali/baksmali.
Moved Android Framework to "prebuilt", as it is just a prebuilt, looks out of
place among .class files.
@SuppressWarnings removed from Duo as there are quite a few unsafe assignments
of raw Duo[] instances to parameterized Duo<> variables in the project, this is
just Java being the primitive boilerplate it is, no point in fighting it.
No end-user changes.
Tested against a full ROM decompile/recompile, no issues found.
* small tweak
* last refinement
* missed a stream
