mtr detects a forced combination if the command line for a test already
includes all options from this combination. options are stored in a perl
hash as (key,value) pairs.
this breaks if the command line has two options with the same name,
like --plugin-load-add=foo --plugin-load-add=bar, and the combination
forces plugin foo.
In particular, this resulted in warnings when running
federated.federatedx_versioning test
if all options from a combination from the combinations file are already
present in the server's list of options, then don't try to run tests
in other combinations from this file.
old behavior was: if at least one option from a combination is
already present in the list...
mysql-test/lib/My/Options.pm:
My::Options::is_set() now matches both option names and values!
mysql-test/lib/mtr_cases.pm:
1. don't merge --plugin-load here, it's too early
2. don't skip combinations that set --plugin-load just because the test needs another --plugin-load.
Skip *only* if test's --plugin-load matches *exactly* --plugin-load of one of the combinations.
3. if skipping all combinations but one, still assign the test to the combination
mysql-test/mysql-test-run.pl:
1. remove dead code - don't set variables that aren't used.
2. bugfix: allow one-letter combination names
3. in the command line, merge all --plugin-load options in one
storage/federated/ha_federated.cc:
bugfix: garbage character in the generated SELECT query

Try to dynamically change option, restart if it fails.
