- fdflags_builtin: only parse the setspec once, since parsing uses
strtok.
Report and patch from Emanuele Torre <torreemanuele6@gmail.com>

builtins/enable.def
- dyn_load_builtin: if BASH_LOADABLES_PATH is set, use only it: don't
fall back to looking in the current directory. This changes the
historical behavior and brings the path behavior more in line with
PATH, but not CDPATH.

examples/loadables/strptime.c
- strptime: new loadable builtin, interface to strptime(3). Takes a
date-time string as its arguments and tries to parse it according
to a number of built-in formats. If successful, it outputs the
result as a number of seconds since the epoch. Understands some
handy shorthands like "now" and "tomorrow".
