memctx: allow extensions to determine what filectxfn should do
Rev 650b5b6e75ed switched the contract for filectxfn from "raise IOError if
file is missing" to "return None if file is missing". Out of tree extensions
need to be updated for that, but for extensions interested in compatibility
with both Mercurial <= 3.1 and default, it is next to impossible to introspect
core Mercurial to figure out what to do.
This patch adds a field to memctx for extensions to use.
