Implement LOCAL_COMPRESSED_MODULE.
- Prebuilts with LOCAL_MODULE_CLASS == APPS and BUILD_PACKAGE that
define LOCAL_COMPRESSED_MODULE := true will be installed compressed
in the system partition.
- The compression algorithm is simple gzip for now.
In addition :
- Compressed modules are not dex-preopted.
- JNI shared libraries are always embedded inside compressed modules,
they are never installed as separate files on the FS.
