Rework TeXLive::TLPOBJ::from_fh to make it faster and shorter.

- move the code for continued lines to avoid double-testing
  (34% speed improvement for this change alone)
- rm support for continued execute, postaction and depend
- use one split rather than many matches to get the command and argument
- merge the code for similar lines
- flatten the big if-elsif-else structure by moving the 'name first' test
- rm useless next statements (they were even slowing things down)
- order the big switch by number of occurences
- factor out $lastcmd update (not faster, but nicer code IMO)
- access $self members directly rather than using methods
- call parse_line directly rather than quotewords
- misc other tune-ups, inc. preferring split over regexes

Overall measured speed improvement: 43%
Sub length: 200 -> 130 lines
