extdiff: pass full paths of `dir1a` and `dir1b` to `_runperfilediff()` Earlier we were passing basename instead of the fullpath and then joining with the tmproot. This is wrong because the user can choose `rev1a` as wdir and in those cases, tmproot should not be joined with the path. I am working on refactoring extdiff logic so that we can have options like `diff --tool` and encountered this. Although this patch in itself makes no difference, however in future when a new caller of `_runperfilediff()` will be added, it will be useful to directly pass on the full paths instead.

hgweb: compatibility of hgweb.cgi template with Python 3 When running Mercurial on Python 3 hgweb expects the config variable to be a bytestring. The solution proposed by Anton Shestakov is to use a byteprefix to the literal string defined cgi script as provided in this patch for hgweb.cgi, contrib/hgweb.fcgi and contrib/hgweb.wsgi. I am not sure whether this covers all relevant templates, but I couldn't find others. Differential Revision: https://phab.mercurial-scm.org/D8978

genosxversion: don't give up if we can't find a path to hg libraries This doesn't work if you have a PyOxidized hg on $PATH, but everything is fine if you just ignore that problem. Differential Revision: https://phab.mercurial-scm.org/D8975

tests: fix test-demandimport.py on Python 3.9 Starting with Python 3.9, importing importlib.resources (indirectly) imports the zipfile module. Therefore, the module is not suitable for the test. Instead, we can use the ftplib module, which is very unlikely to be imported during the test run.
