Add [-q] [-t TYPEREGEXP] [NAMEREGEXP] args to info [args|functions|locals|variables]

Main changes are:
* stack.c: Add two regexp preg and treg to print_variable_and_value_data
  and used them inside do_print_variable_and_value to filter the
  variables to print.

* symtab.h: Add a new function bool treg_matches_sym_type_name, that
  factorises type matching logic.

* symtab.c: Add type/name matching logic to 'info functions|variables'.

* stack.c : Add type/name matching logic to 'info args|locals'.
