Load state snapshot rather than booting to start emulator.
This patch adds support for an optional file "snapshots.img" in the
data directory of an AVD. This file should be an image formatted with
the qcow2 file system and will be mounted on -hdb when the emulator
starts up. If present, the emulator will attempt to load the snapshot
named "default-boot" from this image, rather than going through the
full boot procedure.
To control the behaviour of this functionality, this patch introduces
the following new command line options for the emulator:
-snapstorage <file>: override the default location of the
snapshot storage file.
-no-snapstorage: do not load the snapshots file, even if an explicit
path is given.
-snapshot <name>: instead of loading "default-boot", load the state
snapshot with the given name.
-no-snapshot: do not load a snapshot, but force a full boot
sequence, even if a snapshots file is mounted. Useful for
creating snapshots.
Note that this functionality is experimental and will be enabled
only if the constant CONFIG_ANDROID_SNAPSHOTS in
android/config/config.h is set to "1" before building. It is turned
off by default.
