Title: Defer filling enum-type mixers information

Currently, all information about all mixers are fetched during mixer_open().
For enum mixers, an additional step gets the string for each enumerated value -
this can lead to a lot of ioctls and take time even when these mixers aren't
used afterward.

Defer fetching integer/string mapping values when needed (when getting/setting
a enum mixer).
