init.rc: Create /storage mountpoint so Dalvik can mark as slave in zygotes

Mount a tmpfs as /storage in order to create a mountpoint, so that Dalvik
can later mark /storage as slave in zygotes.

Must mount in early-init as some devices' init.hardware.rc populate
/storage then, which the tmpfs would overwrite if mounted later.

Must use tmpfs as rootfs can't be bind mounted (otherwise "mount rootfs
/storage /storage bind" would work as an alternative).
libsuspend: compile as a static library

Compile libsuspend as a static library as well, currently needed by the charger
code in some cases.

charger: Do not suspend when disconnecting from charger

The device should be power off when disconnecting from charger.
If the device enter to suspend, the device couldn't handle the power off
process. So the device shouldn't suspend to handle the power off at that time

Init: Allow building of init that is compatible with second init boot

When using second init init has already set up /dev /proc, etc
this will prevent duplicate mount points for those
Define BOARD_USE_NO_DEVFS_SETUP := true to use
