- renamed "rnd" to "my_rnd" as the name was too generic (and is an exported
symbol in libmysqlclient) (thanks to Dennis Haney for the initial patch)
- cleanup: removed client/password.c (not used at all) and
libmysql/password.c (should rather be a symlink to sql/password.c instead)
- applied HPUX11 portability fix for char_val declaration to sql/password.c
(taken from libmysql/password.c)

libmysql/Makefile.am:
- removed dead piece of code ($qs was not defined)
- symlink password.c from the sql directory
libmysqld/Makefile.am:
- use password.c from the sql directory instead
sql/item_func.cc:
- replaced "rnd" with "my_rnd"
sql/mysqld.cc:
- replaced "rnd" with "my_rnd"
sql/password.c:
- replaced "rnd" with "my_rnd"
