Uoti Urpala 7e366113f7 options: add "choice" option type, use for -pts-association-mode 
Add a "choice" option type. Options of this type take a string as
input and set an int option variable to the value corresponding to the
string. The string->int mapping is option-specific and is given in the
option definition. Strings not found in the mapping are rejected as
invalid option values.

Change the option -pts-association-mode to use this new option type
and accept values "auto, decoder, sort" instead of "0, 1, 2". The
change in accepted values shouldn't cause problems as this option is
not appropriate to use in normal user config files.
