Working p2, eliminate 00admin

This required a fair amount of shuffling stuff around, as can be seen.
Fortunately, now things ought to be able to run more or less standalone
again.

I also figured out a way to have the build system be a tad smarter about
not rebuilding shared stuff, although you still install the exact same eris
binary and /service subdirs for mcp and p2.  But at least you only have to
change one place in the source code now.

This directory is for things that multiple packages need.
For example, eris httpd is used by mcp, p2, and inferno.
This directory does not create its own package, though.
