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.

init: Add "export_rc" command to export env from a specified file

New export_rc command to import environment variables from
a specified file at the time the command is executed.

Differences between "import" and "export_rc":
1) export_rc can only import environment vars
2) export_rc is performed when the command
   is executed rather than at the time the
   command is parsed (i.e. "import")

Example:
in /init.rc:
    on post-fs
        export_rc /system/etc/init.xyz.rc

in /system/etc/init.xyz.rc:
    export LD_PRELOAD /system/lib/libxyz.so

init: Allow basic environment variable expansion in env assignment

Allow environment variable expansion in 'export' command if the
value begins with "${_var_}" (where "${_var_}" will be replaced
with the current value of environment variable _var_).  Expansion
will only occur one time.

e.g.
export BOOTCLASSPATH ${BOOTCLASSPATH}:/system/framework/abc.jar

init: Fix serial number display for semc msm7x30 devices

Add proper check since semc msm7x30 bootloader exports

system: core: increase the polling time for remount_ro to 3600

eMMC4.5 introduces an addition of cache on the device.
We experienced long flush durations in some of the devices,
and therefore the adb reboot resets the target before the flush
completes.
Latest tests show that increasing it to 2400 wasn't enough thus
it was increased to 3600.

restorecon_recursive("/sys") speed boot time

Currently, the restorecon_recursive("/sys") call in
init.c takes approx 2 seconds on hammerhead. This change
reduces the delay to 1.2 seconds.

1) Avoid double stat call when using nftw (time savings
of 0.3 seconds)
2) Avoid the repeated calls to is_selinux_enabled() (time
savings of 0.5 seconds)

Avoid calling lsetfilecon if the file is already properly
labeled. This doesn't speed up the restorecon on /sys,
but it should help when handling files on /data.

Squashed file permission fixes for "adb push"

adb: configure /system file permission with fs_config

adbd changes the permissions of files uploaded by copying
owner's permission to group and other. This causes kernel
load failure if any changes are made to kernel modules
followed by ``adb push'' or ``adb sync'' because file mode
644 would become 666.

The change uses fs_config to get the target mode of files.

In addition, the SELinux file label is set incorrectly
on synced files. Set the label properly.

Bug: 12264775

Fix "adb push /sdcard/filename"

Don't assume that calling chown(filename, getuid(), getgid())
will always succeed. In the case of /sdcard, a file you create
will be owned by root, so the chown call will fail.

Instead, use uid=gid=-1 so that the chown call is truly a no-op.

Ignore the results of calling chmod. Again, for /sdcard, the
chmod call will never succeed, because the file isn't owned by
the shell user.

Add support for socket security context specification.

Add an optional argument to the socket option for specifying
a SELinux security context for the socket.  Normally the socket
security context is automatically computed from the service security
context or set using the seclabel option, but this facility allows
dealing with two scenarios that cannot be addressed using the existing
mechanisms:
1) Use of logwrapper to wrap a service.
In this case, init cannot determine the service security context
as it does not directly execute it and we do not want logwrapper
to run in the same domain as the service.

2) Situations where a service has multiple sockets and we want to
label them distinctly.
