highlight: add highlightfiles config option which takes a fileset (issue3005)
Highlight extension lacked a way to limit files by size, by extension, and/or
by any other part of file path. A good solution would be to use a fileset,
since it can check file path, extension and size (and more) in one expression.
So this change introduces such an option, highlighfiles, which takes a fileset
and on each request decides if the requested file should be highlighted.
The default "size('<5M')" is, in a way, suggested in issue3005.
checkfctx() limits the amount of work to just one file (subset kwarg in
fileset.matchctx()).
Monkey-patching works around issue4568, otherwise using filesets here while
running hgweb in directory mode would say, for example, "Abort: **.py not under
root", but this fix is very local and probably far from ideal. I suspect there
to be a way to fix this for the whole hgweb and resolve the issue, but I don't
know how to do it.
