David Anderson dbc99dc0d2 paths: use /var/db for state on BSDs, and /var/run for sockets.
On BSD, /var/db is what linux calls /var/lib.

On modern linux, /run and /var/run are the same directory, but
on BSD the correct path is /var/run, so use that.

Fixes #79

David Anderson 21fc5ec371 cmd/mkpkg: support specifying that a package replaces another.
Both RPM and Deb require us to specify both Replaces and Conflicts:
Conflicts tells them that the packages cannot coexist on the system,
Replaces tells them which one to keep.

David Crawshaw d417be6a4b controlclinet: clone filter.MatchAllowAll
This avoids a non-obvious data race, where the JSON decoder ends
up creating do-nothing writes into global variables.
