about a while(0); statement.  This should fix (part of) Issue #176.

lock->writer_thread invalid, so that Valgrind will catch more errors.
This is related to Issue #175.

sync_array_object_signalled(): Add a (void) cast to eliminate a gcc warning
about the return value of os_atomic_increment() being ignored.

rw_lock_create_func(): Properly indent the preprocessor directives.

rw_lock_x_lock_low(), rw_lock_x_lock_func_nowait(): Split lines correctly.

rw_lock_set_writer_id_and_recursion_flag(): Silence a Valgrind warning.
Do not mix statements and variable declarations.

Add the copyright notice to the non C files.

To the files touched by the Google patch from c4144 (excluding
include/os0sync.ic because later we removed Google code from that file):

* Remove the Google license
* Remove old Innobase copyright lines
* Add a reference to the Google license and to the GPLv2 license at the top,
as recommended by the lawyers at Oracle Legal.

Add Google's license into COPYING.Google.

Add the full text of the GPLv2 license into the root directory of the
plugin. In previous releases this file was copied from an external source
(https://svn.innodb.com/svn/plugin/trunk/support/COPYING) "manually" when
creating the source and binary archives. It is less confusing to have this
present in the root directory of the SVN branch.

Fix the failing mysql-test partition_innodb, which failed only if run after
innodb_trx_weight (or other test that would leave LATEST DEADLOCK ERROR into
the output of SHOW ENGINE INNODB STATUS). Find further explanation for the
failure at the top of the added patch partition_innodb.diff.

Fix pathname of the file to patch.

test. The default value of innodb_thread_concurrency is changed to 0
(from 8) via r4163.

The old default was 8.

(followup to r4145) Non-functional change:

Change the os_atomic_increment() and os_compare_and_swap() functions
to macros to avoid artificial limitations on the types of those
functions' arguments. As a consequence typecasts from the source
code can be removed.

Also remove Google's copyright from os0sync.ic because that file no longer
contains code from Google.
