--gdb now accepts an argument, it will be passed to gdb as a command.
multiple commands can be separated by a (non-standard and not escapable)
delimiter - semicolon (;).
Old usage with a bare --gdb continues to work too, of course.

If a mtr test runs multiple servers and only some of them get
restarted on whatever reason with new command-line parameters,
then subsequent mtr test may fail, because no cleanup is performed.
Replication and Galera test suites are affected.
In the mtr script, there is a server_need_restart function
that decides whether we need to start a new mysqld process before
the new (next) test. If the mysqld parameters were changed in the
previous test - not necessarily the parameters of the primary mysqld
server, maybe even the secondary server parameters - this function
decides to start a new mysqld process. But since it does not remove
the old (changed) parameters, the new process starts with the
parameters changed by the *previous* test.
To correct this error, we must delete the modified process
parameters after checking that they have been changed during
the previous test.
This patch also simplifies and makes more stable the
galera_drop_database test, during debugging of which this
problem was detected.

If a mtr test case has started two mysqld processes (replication tests),
then kills the first one and kills the second one before starting the
first (so at some point there are two mysqlds down), then the ./mtr
waiting process bricks and forgets to monitor the "expect" file of the
first mysqld, so it never gets started again, even when its contents is
changed to "restart".
A victim of this deficiency is at least galera.galera_gcache_recover.
The fix is to keep a list of all mysqlds we should wait to start, not
just one (the last one killed).
Analyze core independently of max-save-datadir and max-save-core setting.
Increment $num_saved_cores only if core was actually saved.
"Move any core files from e.g. mysqltest" independently of
max-save-datadir setting. Note: it may overwrite core from mysqld, which
might not be desired (it did work this way even before).
Added --skip-test-db option to mysql_install_db. If specified, no test
database created and relevant grants issued.
Removed --skip-auth-anonymous-user option of mysql_install_db. Now it is
covered by --skip-test-db.
Dropped some Debian patches that did the same.
Removed unused make_win_bin_dist.1, make_win_bin_dist and
mysql_install_db.pl.in.
This reverts commit 72deed5988
which was merged as commit 29d4ac2ceb.
The change caused regressions, such as mysql-test-run failing
to run at all with --valgrind, or aborting on Windows on the
first test failure.
