[RFC 1/4] Add "base" parameter to string_to_uint_ex

[Sahil Siddiq]

Add a "base" parameter to string_to_uint_ex instead of
hardcoding the base to 10.

* src/strace.c (is_uid_gid_pair): Pass base 10 as argument.
* src/string_to_uint.c (string_to_uint_ex): Introduce "base" parameter.
* src/string_to_uint.h: Likewise.
* src/util.c
  (parse_ts): Pass base 10 as argument.
  (set_tty_index): Likewise.
  (parse_fdinfo_pid): Likewise.
