MDEV-14265 - RPMLint warning: shared-lib-calls-exit

Browse source 
find_type_or_exit() client helper did exit(1) on error, exit(1) moved to
clients.

mysql_read_default_options() did exit(1) on error, error is passed through and
handled now.

my_str_malloc_default() did exit(1) on error, replaced my_str_ allocator
functions with normal my_malloc()/my_realloc()/my_free().

sql_connect.cc did many exit(1) on hash initialisation failure. Removed error
check since my_hash_init() never fails.

my_malloc() did exit(1) on error. Replaced with abort().

my_load_defaults() did exit(1) on error, replaced with return 2.

my_load_defaults() still does exit(0) when invoked with --print-defaults.
