Quicker test collection and better output with --start[-dirty]

Adding @<platform> syntax

Output would match an empty result file but we don't check
Allow empty output IFF there is an empty result file.

Set to one week for testcase and suite timeout
Also set one day timeout for PID file creation (not currently needed in 5.1 but might become, and is needed in azalea)

Variable name mismatch
Map variable have_innodb=YES to innodb=ON

Bug in Perl
Scrap attempt to do this smartly on AIX, just drop the test and assume it's OK
This commit undoes the previous push and adds a line to ignore on AIX

Bug is actually in Perl
Fixed by trapping and ignoring error from IO::Socket::UNIX

Small amendment to original fix, as it did not work in azalea
Need to handle combinations, would eventually break in 5.1 too

Also fixed mysqld.cc to avoid popup-boxes

Change of variable states in Bug 19027 was not backported to v1
Changed ne "TRUE" to eq "OFF"

General problem: some test cannot run in V1, expect more in future
Implement general mechanism for listing incompatible tests

Server args containing spaces do not work on Windows
Fixed my_safe_rprocess-win to re-apply "" around such args

Fix the name....

Updated to use general_log[_file] and slow_query_log[_file]

Added search for example plugin in lib/mysql/plugin

Let the user specify 'auto' for parallel value
Also set --parallel=auto in default.push so we can get this tested.

Added calls to mtr_report_stats() also after timeout or too many failures

Adding "w# " before the test result
Also enable --parallel=2 so this can be tested.

On 64-bit Windows: querying MERGE table with keys may cause
server crash.The problem is generic and may affect any statement
accessing MERGE table cardinality values.
When MERGE engine was copying cardinality statistics, it was
using incorrect size of element in cardinality statistics array
(sizeof(ptr)==8 instead of sizeof(ulong)==4), causing access
of memory beyond of the allocated bounds.

Protected '' in connect command with ""

The fix is to allow myisamchk to use >4G key_buffer_size on win64

Incorrection assumption about delimiter character in connection command

doesn't find 'logger'

Due to a variable quoting mistake, the $PATH environment
variable isn't parsed correctly when searching for the
existence of the desired executable(s) (logger in this 
case).

This patch removes the quotes.

check_command_args() always looks for the first , (or whatever)
Extended check_command_args() to let arguments be quoted
Added test in mysqltest.test

The problem is that the server failed to follow the rule that
every X509 object retrieved using SSL_get_peer_certificate()
must be explicitly freed by X509_free(). This caused a memory
leak for builds linked against OpenSSL where the X509 object
is reference counted -- improper counting will prevent the
object from being destroyed once the session containing the
peer certificate is freed.

The solution is to explicitly free every X509 object used.

HAVING
            
When calculating GROUP BY the server caches some expressions. It does
that by allocating a string slot (Item_copy_string) and assigning the 
value of the expression to it. This effectively means that the result
type of the expression can be changed from whatever it was to a string.
As this substitution takes place after the compile-time result type 
calculation for IN but before the run-time type calculations, 
it causes the type calculations in the IN function done at run time 
to get unexpected results different from what was prepared at compile time.
                  
In the CASE ... WHEN ... THEN ... statement there was a similar problem
and it was solved by artificially adding a STRING argument to the set of 
types of the IN/CASE arguments at compile time, so if any of the 
arguments of the CASE function changes its type to a string it will 
still be covered by the information prepared at compile time.

stop/start slave
      
When stopping and restarting the slave while it is replicating
temporary tables, the server would crash or raise an assertion
failure. This was due to the fact that although temporary tables are
saved between slave threads restart, the reference to the thread in
use (table->in_use) was not being properly updated when the restart
happened (it would still reference the old/invalid thread instead of
the new one).
      
This patch addresses this issue by resetting the reference to the new
slave thread on slave thread restart.
