This allows to eg use --mem or --parallel for better performance on big boxes.

Don't ever build it, and don't include it in source tarballs.
(we keep the sources in bzr to not get conflicts on every upstream change).

This is needed to fix failures seen in Buildbot (main.ctype_gbk_binlog).
Problem is that some tests did not RESET MASTER, causing them to pick up random
binlog files depending on prior tests.

(These are by their nature difficult to test reliably due to differences in timing).

Fix trivial typo in BUILD/* scripts.

BUILD/SETUP.sh:
  Fix typo.
mysql-test/mysql-test-run.pl:
  Fix mysql-test-run.pl to be able to find plugins used in testing also when running the
  test suite from an installed mysqld package.

 - mysqlslap result file update after merge.
 - Fix skipping certain tests when running test suite as root, got broken somehow.

mysql-test/mysql-test-run.pl:
  Somehow skipping tests when running as root got broken. The mysqltest if() no longer seems
  to accept YES as a true value, so use 1 for true value instead.
mysql-test/r/mysqlslap.result:
  Result file update after change in engine behaviour of mysqlslap.
mysql-test/t/mysqld_option_err.test:
  This test does not work when run as root.

Merge Percona microsec_process patch.
Includes lots of after-merge fixes, Windows fixes, and other misc. small fixes.

mysql-test/suite/rpl/t/rpl_binlog_corruption.test:
  Disabled the test for Windows (see bug #47639)
mysql-test/suite/rpl/t/rpl_killed_ddl.test:
  Disabled the test for Windows (see bug #47638)
vio/viosocket.c:
  Added an implementation of vio_poll_read for Windows.
  Winsock does not support the poll function.
  So the existing generic implementation of vio_poll_read
  could not be used for Windows.

Ability to stop mysql-test-run.pl temporary (useful for them who run buildbot slave on thier work computers)

This adds a TIME_MS column to SHOW FULL PROCESSLIST and
INFORMATION_SCHEMA.PROCESSLIST that works like the TIME column, but
in units of milliseconds with microsecond precision.

Note that this also changes behaviour of the existing TIME column. In
the MySQL server, the TIME column changes when a thread sets @TIMESTAMP.
This is contrary to documentation and also potentially confusing, so
could in any case be considered a bug. With this patch, to ensure
consistency between TIME and TIME_MS, setting @TIMESTAMP has no effect
on either value.

Add a test case for the TIME and TIME_MS columns.
Update existing test cases for changed behaviour.

    mysqlslap: setting --engine does not get replicated
    http://bugs.mysql.com/bug.php?id=46967

and
    mysqlslap: specifying --engine and --create does not
    work with --engine=<storage_engine>:<option>
    https://bugs.launchpad.net/maria/+bug/429773

Problems were that an --engine=<storage_engine> was translated
to a "set storage_engine = <storage_engine>", wich is _not_
replicated. A --engine=<storage_engine>:<option> was not always
properly parsed and in some cases crashed.

Fixed by eliminating "set storage_engine = ..." and adding
proper DDL generation. Initialized an unitialized buffer to
prevent crashes and fixed to use proper pointer for in
case of --engine=<storage_engine>:<option> being the last
element in list of --engines.

Also cleaned up code for better readability.

Q: Should MySQL's replication actually replicate a
   "set storage_engine = ..." command or not?
A: No it should not. It is documented here:
   http://dev.mysql.com/doc/refman/5.1/en/replication-features-variables.html
   ...
   "The storage_engine system variable is not replicated, which is a
   good thing for replication between different storage engines." ...

Before the patch, mysqlslap was behaving this way:

After my final patch, mysqlslap now runs like this:
