[gentoo-dev] extend profiles.desc to include "experimental" profiles

[Mike Frysinger]

after dealing with m68k, mips, and the *-fbsd ports, i think we could do with 
a new state for profiles.desc.  the new field would simply be "exp" to 
indicate that the profile is experimental and that qa tools should generally 
not issue warnings about them.  so in repoman's default mode, you wouldnt get 
any warnings, but if you were to run it in full mode, you'd see stuff like 
normal.  this is useful for new projects which are still in the process of 
merging (like *-fbsd, m68k, and any new hardware i get my hands on) and are 
not really ready for "dev" marking.  there are plenty of warnings in packages 
right now due to these profiles being labeled as "dev" that are the sole 
problem of the keyword maintainer in question and not the package maintainer.
