[ecasound] -kog, -kf and LV2 testing needed

quite a bit of activity in the git master again, so time to upload
a snapshot tarball again.


The snapshot tarball is at (matching git HEAD

Feedback needed on

I'd welcome feedback (read: "ack, nothing odd found" or "stop the press"):

   - -kog and -kf, these have been basicly rewritten (only sane
     way to close the bugs there were)

   - new configure checks for liblilv now that 0.14.2 is
     officially out
         -> LV2 support should be enabled by default if you
            have sufficiently new liblilv installed (newer
            than 0.5.0)

   - in general, more stress-testing for the LV2 support

Example test sequences

Some samples to test (using alsa as outpu here, replace with JACK or a
file, ..). All of these use the same params for swh-plugins 'analogueOsc',
which is available both as a LADSPA and a LV2 plugin (so you can test with
both). The syntax for '-kog' is pretty scary (and there was an ancient doc
bug in ecasound(1) man page concerning it), so I'm fairly so very, very
few people have ever used these).
