staging: Remove the Android logger driver

Browse Source 
With the relase of Lollipop, Android no longer
requires the logger driver.

There are three patches which the android dev's
still need before they drop logger on all their
devices:

[PATCH v4 1/5] pstores: use scnprintf
[PATCH v2 2/5] pstore: remove superfluous memory size check
[PATCH 3/5] pstore: handle zero-sized prz in series
[PATCH v4 4/5] pstore: add pmsg
[PATCH 5/5] pstore: selinux: add security in-core xattr support for pstore and debugfs

But these seem to have been acked and are hopefully
queued for upstream.

So this patch removes the logger driver from staging.

It is, in theory, a good memory allocator for low-memory devices,
because it can discard shared memory units when under memory pressure.

This adds support for system-wide logging using four log buffers.
These are:
1: main
2: events
3: radio
4: system
Log reading and writing is performed via normal Linux reads and
optimized writes. This optimization avoids logging having too
much overhead in the system.
