vold: restore 4.4 sdcard logic

Mount points in 4.4 are always fuse-wrapped to provide granular
permission. Unix file systems no longer need to be manually
fuse-wrapped by us.

vold: Add selinux support to ext4

Squashed commit of the following:

Author: Pawit Pornkitprasan <p.pawit@gmail.com>
vold: mount ext4 with forced SELinux context

Always mount voldmanaged ext4 partitions with the SELinux sdcard_external
context. For other file systems, this is done via the genfs_context,
but since ext4 supports SELinux natively, it must be set here.

vold: force SELinux context only for sdcard

Google uses this code to mount ASEC as well and we shouldn't force
their SELinux contexts

f2fs: disable fsck check

fsck.f2fs does not fix any inconsistencies "yet".

Disable fsck routine as this is just wasting time consumed to mount f2fs volumes.

The kernel can determine if a f2fs volume is too damaged that it shouldn't get mounted.

We should wait for f2fs-tools version higher than v1.3.0.
(fsck.f2fs for fixing inconsistencies is a work-in-progress)

vold: Support unmount <path> detach

This is to be used primarily (exclusively?) in recovery.  In prior
versions, the local file was copied to tmpfs so that everything could
be unmounted cleanly.  But the current version uses the local file
in-place due to constraints with low memory devices.  This prevents
the filesystem that holds the local file from being unmounted in the
normal way.  So in order to avoid leaking a mount, the filesystem that
holds the local file must be unmounted with the detach flag.
