Add check that there is a RHS of the expression
Added to mysqltest.test

Var's string value was not 0-terminated if intially null.
While at it, also removed some reported memory leaks
Added sanity check, setting val_len=0 if val==0

Added option --debug-common which sets 'd' debug flags to the suggested list

Fixed as suggested in the .inc file and two tests
Could not reproduce problem, but tested tests on Windows

Stripping quotes in let was a bad idea, will not fix
Added code to strip quotes from rhs in comparisons

It does work in general, the problem here was that the test name
'alter_table' matches 'main.alter_table-big' which has already been found.
Fixed by matching more explicitly (with/without suite name)

If mysqltest dies, mtr waits to see if mysqld dies too within 100ms
But in that case, it should not care about expected crash
Fix: jump past the code that checks the expect file

Follow-up discussed with Reporter:
Avoid hard shutdown after test failure, if caused by server log warning
  AND we are running valgrind
More general pick-up of valgrind summaries, order may apparently vary
Do exit(1) if we did find valgrind summary warnings

Evaluation would start with the space and thus ignore the $
Added while() to skip past white space

Results from query is sent for evaluation
Break recursion by asking for ` to be ignored

 - Speed up replicated NDB test by havin mysqltest poll every 100ms (instead
   of every second) in sync_master_with_slave. Default epoch
   timeout is 100ms, so that make sense.

 - use $bindir instead of $basedir when looking for binaries
 - NOTE! the $ENV{NDB_EXAMPLES_*} will be reworked so that
  mtr.pl does not need to set them up.

      Added more parsing in do_block()
      Limitation: left operand must be variable
      Also changed var_set_int from 57036 to var_check_int
      Added tests to mysqltest.test
      Some tests can now be simplified but will take this later
      Updated after comments, now white space around operator not needed

There were actually more problems in this area:
  Slaves (if any) were unconditionally restarted, this appears unnecessary.
  Sort criteria were suboptimal, included the test name.
Added logic to "reserve" a sequence of tests with same config for one thread
Got rid of sort_criteria hash, put it into the test case itself
Adds little sanity check that expected worker picks up test
Fixed some tests that may fail if starting on running server
Some of these fail only if *same* test is repeated.
Finally, special sorting of tests that do --force-restart

Option was incorrectly coded without an argument
Added the missing =s

  Simplified cases where a select was used to compare variable against ''
