builddeb: read default distribution and codename from lsb_release This makes `make deb` place packages into a more appropriately named directory instead of just "debian-unknown".

builddeb: remove unused --debbuilddir option Looks like it was never used and after 7f49efcaa9b4 it can be removed.

builddeb: add --distid option to specify Distributor ID This allows builddeb to handle distributions that are not Debian. Distributor ID is reported by lsb_release --id, and in case of builddeb it's usually Debian or Ubuntu.

builddeb: rename --release option to --codename Debian and Ubuntu releases have both codenames and traditional version numbers. An entire "branch" of releases is referred to by its codename, and version numbers (e.g. 8.2, 14.04.3) are used to address individual releases. Since we use codenames for building .deb packages, let's call the option and the variable appropriately.

histedit: get rid of state.rules Now we are using state.actions instead of state.rules everywhere.

histedit: change state.rules uses to state.actions This change is replacing most of state.rules uses with state.actions uses. The next change will change histeditstate class to actually uses state actions.

histedit: add tostate method to histedit action the format of rules that we store in state file format is different from the rule format that we present to users. We need a way of dumping action to state file.
