check mail regarding LinkSys. add info to README, with note.

RELEASE next:

test search parsing:
  unterminated strings: should cause error every time
  test other and any strings!
try intel upnp tools?

---
from Daniel Bachfeld:
FYI: the twonkyvision ini-File for the musicserver contains a specific
setting for the m1000:

# param -nosearch [n] = set to 1 to supress search support
# mainly needed for ROKU which brings own UI when search is enabled
nosearch=0

The vendor suggest to set it to 1. However, it works still with 0

mp101: test uncompressed wave  playing
read UPNP device architecture.
add section to README about relevant standards and documentation
internal:
  remove generic entry detail. instead support the following:
    EntryDirectoryInfo - including local_path!
    EntryTagInfo
announce on www.media-servers.com: forums?
clean up upnp support. as much as necessary and CORRECT is the keyword.
  upnp: What do we do with A_ARG_* variables? Handle in get_variable_request?
  upnp: Subscriptions: What is subscribable?!

RELEASE V2:

convert into supported audio format in realtime (mp3 encoder or just decode to wave?)
when do we need to report 'res' URL? check contentdir docs. why doesn't twonky do it?
improved debugging for webserver.c, metadata.c, contentdir.c
implement variables such as UpdateID (always returns 0!)
check out .m3u support correctly
check out radio support, simple and advanced user configuration of url & item data
log connected control points
implement stuff in connectmgr.c, contentdir.c
set up web server to serve all SPCD documents
communication over subnets: does it work in Windows? if yes, then something must be incorrectly set up in linux (multicast?)
support other formats than mp3. find out what formats are supported. WAVE?

threading: do we need mutexes to synch data?

DISTANT FUTURE:

gnulib: use closeout?
external or (why not) native rtsp support
become a full GNU project - hand over copyright to FSF, if they want it
caching of metadata, even across restarts (storing to cache file), keeping partial tree in memory
virtual representation vs physical representation
log as soon as a control point connects to us. requires libupnp modifications/feature additions!
