gdbsupport: make use of safe-ctype functions from libiberty
Make use of the safe-ctype replacements for the standard ctype
character checking functions.
gdbsupport/ChangeLog:
* gdbsupport/common-utils.cc: Change 'ctype.h' include to
'safe-ctype.h'.
(extract_string_maybe_quoted): Use safe-ctype function versions.
(is_digit_in_base): Likewise.
(digit_to_int): Likewise.
(strtoulst): Likewise.
(skip_spaces): Likewise.
(skip_to_space): Likewise.
