This was caused by the short_option_1-master.opt file that had the
option -T12, which means (among other things) to use blocking for
sockets. This was supported up to MariaDB 10.4, but not in 10.5 where
we removed the code that changes blocking sockets to non blocking in
case of errors.
Fixed by ignoring the TEST_BLOCKING flag and also by not using the -T12
argument in short_option_1.
Other things:
- Added back support for valgrind (the original issue had nothing to
do with valgrind).
- While debugging I noticed that the retry loop in
handle_connections_sockets() was doing a lot of work during shutdown.
Fixed by not doing retrys during shutdown.

Before this fix, the server did not recognize 'short' (as in -a)
options but only 'long' (as in --ansi) options
in the startup command line, due to earlier changes in 5.5
introduced for the performance schema.
The root cause is that handle_options() did not honor the
my_getopt_skip_unknown flag when parsing 'short' options.
The fix changes handle_options(), so that my_getopt_skip_unknown is
honored in all cases.
Note that there are limitations to this,
see the added doxygen documentation in handle_options().
The current usage of handle_options() by the server to
parse early performance schema options fits within the limitations.
This has been enforced by an assert for PARSE_EARLY options, for safety.
