Avoiding a theoretically possible crash (pthread_mutex_lock(0)) which could (at least in POSIX Threads books)
happen on SMP machines, when a thread is going to wait on a condition and it is KILLed at the
same time.
Cleaning code a bit by adding a test in enter_cond() that we have the mutex (was already the case in all places
where it's called except one which is fixed here).

The problem was that (for any storage engine), the created temporary table was not removed if CREATE SELECT failed (because
of a constraint violation for example). This was not consistent with the manual and with CREATE SELECT (no TEMPORARY).

BUG#4506 "mysqlbinlog --position --read-from-remote-server has wrong "# at" lines",
BUG#4553 "Multi-table DROP TABLE replicates improperly for nonexistent table" with a test file.
It was not possible to add a test for BUG#4506 as in the test suite we must use --short-form
which does not display the "# at" lines.

Fix for BUG#4375 "Windows specific directories are copied during
replication": in the Windows version of my_dir(), do not show hidden
or system files which Windows sometimes creates in the root directory
of drive (like RECYCLER and SYSTEM VOLUME INFORMATION directories) (so
this problem showed up only when the datadir was the root dir of a
drive).
This will make SHOW DATABASES display better, and will do no harm to
MySQL. For example, DROP DATABASE will not miss some files, as MySQL
creates no hidden or system files.

if a command has a comment at the end of line, like:
error 2002 ; # this is error 2002
then the parsing of comment should not make mysqltest
forget about the value of expected error.
Reason it forgot it (so the next query caused the test to fail)
is that internally the above line is 2 queries.

processlist on slave":
we now report in SHOW PROCESSLIST that we are writing to the temp
files or loading the table. When we are writing to the tmp file:
| 3  | system user |                 |    | Connect | 6    | Making temp file /tmp/SQL_LOAD-2-1-2.data | 
and when we are actually loading the .data temp file into the table:
| 3  | system user |                 | test | Connect | 2    | | LOAD DATA INFILE '/tmp/SQL_LOAD-2-1-2.data' INTO TABLE `t` <...> |
