[LAD] RFC: Default discovery paths for LADSPA, LRDF, LV2 and DSSI (and more?)

Hello

LADSPA, LV2 and DSSI specifications do not reccomend default discovery
paths where hosts may look for plugins, which IMO is bad for the end
user because:

* end users shouldn't be asked to know about path environment
variables by reading documentation in header files or looking for it
on the web;
* when their environment path variables are not set, some hosts choose
to scan some hard-coded directories, but this changes among hosts and
gets a lot worse on non UNIX-like operating systems (read Windows) -
for example some might look inside some subdirectory of the current
user's home, others might only look in /usr/lib/<api>, etc.

Hereby I propose some default paths which could be used, in the hope
that API authors lurking around here might want to recommend them and
host authors might want to use them:

LADSPA
  Unix-like OSes with FHS/Unix-like filesystem layout:
/usr/lib/ladspa, /usr/local/lib/ladspa, ~/.ladspa
  Windows: %PROGRAMFILES%\LADSPA, %APPDATA%\LADSPA
  Mac OS X: /Library/Audio/Plug-Ins/LADSPA, ~/Library/Audio/Plug-Ins/LADSPA

DSSI
  Unix-like OSes with FHS/Unix-like filesystem layout: /usr/lib/dssi,
/usr/local/lib/dssi, ~/.dssi
  Windows: %PROGRAMFILES%\DSSI, %APPDATA%\DSSI
  Mac OS X: /Library/Audio/Plug-Ins/DSSI, ~/Library/Audio/Plug-Ins/DSSI

LV2
  Unix-like OSes with FHS/Unix-like filesystem layout: /usr/lib/lv2,
/usr/local/lib/lv2, ~/.lv2
  Windows: %PROGRAMFILES%\LV2, %APPDATA%\LV2
  Mac OS X: /Library/Audio/Plug-Ins/LV2, ~/Library/Audio/Plug-Ins/LV2

Plus, we could do the same for LRDF data:
  Unix-like OSes with FHS/Unix-like filesystem layout:
/usr/share/ladspa/rdf, /usr/local/share/ladspa/rdf, ~/.ladspa/rdf
  Windows: %PROGRAMFILES%\LADSPA\rdf, %APPDATA%\LADSPA\rdf
  Mac OS X: /Library/Audio/Plug-Ins/LADSPA/rdf,
~/Library/Audio/Plug-Ins/LADSPA/rdf

What do you think about it?

Stefano
