Serve multiple repository with a single boar serve

[GoogleCodeExporter]

I'm currently evaluating boar to be used as an asset manager for my company's 
projects.
For the following reason, I will prefer to use one repository per project
instead of using boar sessions:
- Snapshot IDs are unique per repository, not per session.
- Ability to move old project repositories in another location

Currently, boar serve can't be used to serve a "repository root", like 
subversion server can do it. Each repository have to be served with a different 
instance of boar serve on a different port.

I have changed a bit the connect_tcp() function and serve command to let 'boar 
serve' act as a meta-server

Usage
# On server
mkdir root
mkdir root/projectA
mkdir root/projectB
boar serve --meta-repo root

# On client
boar --repo=boar://localhost:10001/projectA mksession Pictures
boar --repo=boar://localhost:10001/projectA import workdir/projectA/Pics 
Pictures
boar --repo=boar://localhost:10001/projectA mksession Movies
boar --repo=boar://localhost:10001/projectA import workdir/projectA/Vidz Movies

boar --repo=boar://localhost:10001/projectB mksession Pictures
boar --repo=boar://localhost:10001/projectA import workdir/projectB/Pics 
Pictures
# ...
