Followup: had forgotten to update mysqltest.test due to changed output - duh!

Put descriptions of plugins into a separate file read by MTR
MTR itself has generalised code to read this and set env. variables
Removed the *SO variables, updated some tests accordingly
New commit: added optional list of plugin names for _LOAD variable
Also made changes for the new AUTH_* plugins

Generalized fix for recursive backtick
Optional arg to eval_expr telling it not to interpret

Added a pattern match to cover combinations
Added to readme file

This patchs adds printing of a file stack (with line numbers)
It does not fix the problem of a failure in the non-first iteration of a loop

(irrelevant for 5.5 and up)

InnoDB Plugin 1.0.14 has been released with MySQL 5.1.54.

Truncate the maximum result length (64-bit wide type) to fit into
the item maximum length (32-bit wide type). This is possible as
this specific branch is only used if the maximum result length
is less than 0x1000000 (MAX_BLOB_WIDTH), which fits comfortably
in a 32-bit wide type.

WIN32 compilation fixes: define ETIMEDOUT only if not available and
fix typos and add a missing parameter.

From a user perspective, the problem is that a FLUSH LOGS or SIGHUP
signal could end up associating the stdout and stderr to random
files. In the case of this bug report, the streams would end up
associated to InnoDB ibd files.

The freopen(3) function is not thread-safe on FreeBSD. What this
means is that if another thread calls open(2) during freopen()
is executing that another thread's fd returned by open(2) may get
re-associated with the file being passed to freopen(3). See FreeBSD
PR number 79887 for reference:

  http://www.freebsd.org/cgi/query-pr.cgi?pr=79887

This problem is worked around by substituting a internal hook within
the FILE structure. This avoids the loss of atomicity by not having
the original fd closed before its duplicated.

Patch based on the original work by Vasil Dimov.

include/my_sys.h:
  Export my_freopen.
mysys/my_fopen.c:
  Add a my_freopen abstraction to workaround bugs in specific OSes.
  Add a prototype for getosreldate() as older FreeBSD versions did
  not define one.
sql/log.cc:
  Move freopen abstraction code over to mysys.
  The streams are now only reopened for writing.

This change is relevant only for 5.1.

Do not use nested AC_CHECK_FUNC() because they result in:

./configure: line 52688: syntax error: unexpected end of file

(which happens only on some platforms and does not happen on others,
I have no idea what is the reason for this)

   Basically take care that disconnects are finished.

- Second scenario checked:
  Ensure via wait routines that the commit comes after the
  processing of the statement which should get finally
  the ER_LOCK_WAIT_TIMEOUT
  --> This should prevent the current bug.
- First scenario checked:
  Ensure via wait routines that the statement is already waiting
  for getting the lock before the commit is given.
  --> No effect on the current bug, but ensure that the right
      scenario is reached.
- Take care that disconnects are finished before the test ends.
  --> Reduce the potential to harm succeeding tests.
- "Mangle" the printout of the current default innodb_lock_wait_timeout value
  --> No need to adjust the test in case the default gets changed in future.

   - remove the superfluous file
   - add an preemptive removal of the outfile before the
     SELECT ... INTO OUTFILE ...
2. Remove an already disabled subtest
   It's functionality is covered by tests in the suite funcs_1.
3. Adjust the formatting within some sub testcase to the formatting used
   in all other sub testcases

This is a null-merge because Bug#59327 is present only in 5.1

AC_CHECK_FUNCS(f1 f2 f3, ACTION_IF_PRESENT)
ACTION_IF_PRESENT is executed if any of f1, f2 or f3 is present.
Fix this misusage, we want the action to be executed if all of the
functions are present.

that aren't strings

Check whether the master and purge thread are active after creating them. Do
not proceed until both threads have started. We do this by checking whether a
slot has been reserved by both the respective threads.
      
Add srv_thread_has_reserved_slot() returns slot no or ULINT_UNDEFINED.
