convert: readd --filemap
To handle merges correctly, this revision adds a filemap_source class
that wraps a converter_source and does the work necessary to calculate
the subgraph we're interested in.
The wrapped converter_source must provide a new getchangedfiles method
that, given a revision rev, and an index N, returns the list of files
that are different in rev and its Nth parent.
The implementation depends on the ability to skip some revisions and to
change the parents field of the commit objects that we returned earlier.
To make the conversion restartable, we assume the revisons in the
revmapfile are topologically sorted.

output the current or given revision of files
Print the specified files as they were at the given revision.
If no revision is given, the parent of the working directory is used,
or tip if no revision is checked out.
Output may be to a file, in which case the name of the file is
given using a format string. The formatting rules are the same as
for the export command, with the following additions:
%s basename of file being printed
%d dirname of file being printed, or '.' if in repo root
%p root-relative path name of file being printed
options:
-o --output print output to file with formatted name
-r --rev print the given revision
-I --include include names matching the given patterns
-X --exclude exclude names matching the given patterns
