StringBlock instances containing UTF-8 strings use a cache to convert
into UTF-16, but using that cache and then using a JNI call to NewString
causes the UTF-8 string as well as two copies of the UTF-16 string to
be held in memory. Getting the UTF-8 string directly from the StringPool
eliminates one copy of the UTF-16 string being held in memory.
This is part 1. Part 2 will include ResXMLParser optimizations.

It allows you to force override the manifest
package listed in the AndroidManifest.xml when
creating an APK file.

Allows the use of UTF-8 for packing resources instead of the
default of UTF-16 for Java. When strings are extracted from the
ResStringPool, they are converted to UTF-16 and the result is
cached for subsequent calls.
When using aapt to package, add in the "-8" switch to pack the
resources using UTF-8. This will result in the value, key, and
type strings as well as the compiled XML string values taking
significantly less space in the final application package in
most scenarios.

The StringPool indicates the length of a string with a 16-bit
integer. If the length of the string is greater than 0x7FFF,
it splits it into two 16-bit integers with the first one
having the high bit set.
The length calculation has a small bug that masks off the
19 bits instead of the first 15 bits as intended.
