init: add detection of charging mode

Based on Prashant Somashekar's patch which is in turn based on techomancer's
patch http://goo.gl/I19GG.

When BOARD_CHARGING_MODE_BOOTING_LPM is set, init will read that
value (usually from /sys) and enable charging mode when set to 1.

This differs from the original patch in that Samsung-specific lpm.rc
is not loaded, but instead, init.rc is loaded using the "charger" class,
which is how AOSP devices handle charging.

The change is because the either the SELinux or the init.rc changes is
causing lpm.rc to not work, and porting lpm.rc to the Android system
is easier than trying to fix it.

init: Fix memory corruption when sanitizing platform paths

This commit fixes code that incorrectly increments s when it
hits the terminator character of the string being sanitized.
This means it will randomly start trashing memory beyond the
end of the string being sanitized until it happens to hit two
NULs (\0\0) which will break it out of the loop.

healthd: charger: only reboot under NORMAL mode

If charger is not launched from normal poweroff charging,
we don't want device to reboot. Just leave charger process
to exit by itself but not reboot when not under NORMAL mode.

init: Check for symlinks with lstat() not open()

Using open() with an O_NOFOLLOW flag will result in a file falsely
being determined to be a symlink if the open fails for another
reason.

For example, a character device that isn't ready due to the
underlying hardware not being initialized yet will fail to open()

An example of this are any CG2900 device files prior to
execution of ste-cg29xx_ctrl

This uses lstat() instead of open() with O_NOFOLLOW to check
whether a file is a symlink or not.

Allow a device to define the max number of service groups in init.h

Certain proprieatary binaries (such as tcmd for instance) require
more than 12 supplementary service groups.  By definiing:
TARGET_NR_SVC_SUPP_GIDS := in BoardConfig this can now be changed
per device.
