This changes allows an fstab to contain multiple lines for a given
mount point.
The lines sharing a mount MUST be after each other.
The 1st matching line is the primary when it comes to mounting
and look ups for wiping.
Mounting based on a mount_point will attempt each dup in turn
until one succeeds.
This is to allow quick experimentations between different FSes.
It does not deal with checkfs yet, because the underlying invocation
of fs-type appropriate fsck does not handle the error code.
Only the primary FS (1st in the dups) is checked.

- Enables fsck.f2fs for partitions with type F2FS.
- Adds support for f2fs as format fs-type.
- f2fs is optional and support is dlopen()d when needed.

Now the map output is only sent to the tombstone, and the entire
contents of /prod/$PID/maps is logged, not just 3 lines. Additionally,
crasher now supports "crasher SIGSEGV-non-null", which attempts to write to a
dereferenced function address, causing a SIGSEGV at a non-zero address.
This new crasher mode can be used to test the new maps output.

Don't follow symlinks. Suggestion from Jann Horn.
Also, add O_CLOEXEC. This prevents file descriptor leakage should
this code ever run in a multithreaded environment.
I'm not sure if either of these changes actually address any
security concerns, but it's harmless, so go ahead and add it.

The system by which debuggerd filters its output to different locations
is now based on an enum called logtype with easy to understand
categories for log messages (like THREAD, MEMORY, etc.) instead of the
old, fairly esoteric scope_flags variable. Now much of the output that
previously went to logcat does not show up on the screen, but all output
can be found in the tombstone file. In addition, the tombstone's
location is now printed so it can be located easily.

When ueventd creates a device node, it may also create one or more
symlinks to the device node. These symlinks may be the only stable
name for the device, e.g. if the partition is dynamically assigned.
A corresponding change with the same Change-Id to external/libselinux
introduces selabel_lookup_best_match() to support looking up the "best match"
for a device node based on its real path (key) and any links to it
(aliases). This change updates ueventd to use this new interface
to find the best match for the device node when creating it.
