[CM] midishare and portmidi packages available

[Rick Taube]

Ive basically finished the reorganization of cm sources except for 
testing and dealing with Windows. tarballs of the new 'breakout 
packages' for midishare and portmidi are now available on the install 
page:
	http://commonmusic.sf.net/doc/install.html#portmidi
	http://commonmusic.sf.net/doc/install.html#midishare

just install them and then use use-system when you want to work with 
them, eg  (use-system :portmidi) . the only incompatible change in 
functionality is that the portmidi function pm:getDeviceDescriptions 
has been renamed to pm:getDeviceInfo

these packages should work in Allegro, CMUCL, CLISP, LispWorks, OpenMCL 
and SBCL.

as a result of the reorganization a number of old source files have 
been moved/removed in the repository, if you want to start from scratch 
you can delete your current cm tree (rm -r cm) and then check out a new 
repository:

	cvs checkout -P cm
