Bug #55873 short startup options do not work in 5.5

Description:
short startup options do not work in 5.5

[ERROR] Buffered error: mysqld: unknown option '-a'
[ERROR] Buffered error: mysqld: unknown option '-l'
[ERROR] Buffered error: mysqld: unknown option '-W'
[ERROR] Buffered error: mysqld: unknown option '-s'

5.1.49 worked fine.

How to repeat:
mysqld --no-defaults --console -a
mysqld --no-defaults --console -l
mysqld --no-defaults --console -W
mysqld --no-defaults --console -s
etc...

Suggested fix:
just remove the short versions of variables and i'll be happy

Thank you for the bug report. Verified on Fedora 13 X86_64:

[miguel@tikal dbs]$ 5.5/bin/mysqld --console -a
100810  8:12:00 [ERROR] Buffered error: 5.5/bin/mysqld: unknown option '-a'

      Bug#55873 short startup options do not work in 5.5
      
      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.
      
      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.

      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.
