[PATCH v5 0/2] rev-parse options for absolute or relative paths

There are a bunch of different situations in which one would like to have an absolute and canonical or a relative path from Git. In many of these cases, these values are already available from git rev-parse, but some values only come in one form or another.

Changes from v4:

* Wrap an internal function.
* Use bitflags.
* Fix memory leaks.
* Explain that --path-format can be specified multiple times and its
  effects if that is done.
* Expand commit message.

Changes from v3:

* Switch to a binary option instead of a number of missing path
  components to skip.

Changes from v2:

* Incorporate multiple missing segment support into the strbuf_realpath
  code.
* Switch some invocations to use DEFAULT_UNMODIFIED, which should not
  result in a change in behavior.
* Rebase, resolving some conflicts.

Changes from v1:

* Add a function to handle missing trailing components when
  canonicalizing paths and use it.
* Improve commit messages.
* Fix broken && chain.
* Fix situation where relative paths are not relative.
