- Added new type GET_STRALC to my_getopt.

- Fixed some bugs, wrongly freed pointers, in some clients.
- Removed unneccessary code.
- Fixed some other minor bugs and added some options into
  variables category, which had accidently been left out earlier.


client/mysql.cc:
  Fixed some wrong freed pointers. Removed unneccessary code.
  Changed some types from GET_STR to GET_STRALC.
client/mysqladmin.c:
  Fixed some wrong freed pointers. Removed unneccessary code.
  Changed some types from GET_STR to GET_STRALC.
client/mysqlcheck.c:
  Fixed some wrong freed pointers. Removed unneccessary code.
  Changed some types from GET_STR to GET_STRALC.
client/mysqldump.c:
  Fixed some wrong freed pointers. Removed unneccessary code.
  Changed some types from GET_STR to GET_STRALC.
client/mysqlimport.c:
  Removed unneccessary code.
  Fixed a bug in option --ignore-lines
client/mysqlshow.c:
  Removed unneccessary code.
include/my_getopt.h:
  Added new type, GET_STRALC. The name stands for GET STRING ALLOC,
  which means that the struct member value and u_max_value are
  strings that must be alloced and freed when used.
  The normal GET_STR works similarly otherwise, except that it's
  arguments are just pointers to strings, not alloced ones.
mysys/my_getopt.c:
  Added support for GET_STRALC

client/mysqlcheck.c
