lowmemorykiller: Compact memory when killing processes

* Memory compaction is never invoked on Android because we avoid swap
   and don't allocate huge pages. Fix it by invoking compaction from the LMK when
   a process is killed to reduce memory fragmentation.

lowmemorykiller: Use asynchronous compaction

Snappy compressor added

from http://code.google.com/p/snappy/

Snappy is a compression/decompression library. It does not aim for
maximum compression, or compatibility with any other compression
library; instead, it aims for very high speeds and reasonable
compression. For instance, compared to the fastest mode of zlib, Snappy
is an order of magnitude faster for most inputs, but the resulting
compressed files are anywhere from 20% to 100% bigger. On a single core
of a Core i7 processor in 64-bit mode, Snappy compresses at about 250
MB/sec or more and decompresses at about 500 MB/sec or more.

Snappy is widely used inside Google, in everything from BigTable and
MapReduce to our internal RPC systems. (Snappy has previously been
referred to as “Zippy” in some presentations and the likes.)

For more information, please see the README. Benchmarks against a few
other compression libraries (zlib, LZO, LZF, FastLZ, and QuickLZ) are
included in the source code distribution. The source code also contains
a formal format specification, as well as a specification for a framing
format useful for higher-level framing and encapsulation of Snappy data,
e.g. for transporting Snappy-compressed data across HTTP in a streaming
fashion. Note that there is currently no known code implementing the
latter.
