[PATCH v2 0/1] repo: add filtering options to "repo structure"

["Mark C. Chu-Carroll" <markchucarroll@fastmail.com>]

"git repo structure" provides a collection of useful information
about the information stored in a repo. In particular, it's
valuable for diagnosing performance issues caused by large objects
stored in a repo.

The current implementation of "git repo stucture" provides summary
information about everything in the repository - all of the
branches, remotes, tags, stashes, and notes. But sometimes
to properly diagnose a problem, it's useful to be able to
get information about the specific part of the repo that's
exhibiting a problem.

Add the option to specify a set of filters in the form
of a list of include and exclude queries. Each of these
specifies a commit or ref or range. The set of objects processed
will consist of all objects reachable from any of the
includes which are _not_ reached exclusively by paths
including any of the excludes.

Updates since v1: this change has been completely rewritten. The
original version implemented filters the same way as
"git-sizer", by selecting object types to include or exclude.
This version drops he type-based filters in favor of
specifying object traversal roots and exclusions.
