libgettextpo: Getting markers (c-format, etc)

[Dwayne Bailey]

You can determine from a file if a marker is set but only if you know
what markers are valid which you then iterate through.  Its tedious to
have to keep a list that might change over time and then try each one.

It would be nice to have a function that returns a list of valid markers
known by Gettext.  But perhaps better to simply have a function that
returns a list of all markers set on that unit.
