tests: add a substitution for ENOENT/ERROR_FILE_NOT_FOUND messages
Automatic replacement seems better than trying to figure out a check-code rule.
I didn't bother looking to see why the error message and file name is reversed
in the annotate and histedit tests, based on Windows or not.
I originally had this as a list of tuples, conditional on the platform. But
there are a couple of 'No such file or directory' messages emitted by Mercurial
itself, so unconditional is required for stability. There are also several
variants of what I assume is 'connection refused' and 'unknown host' in
test-clone.t and test-clonebundles.t for Docker, FreeBSD jails, etc. Yes, these
are handled by (re) tags, but maybe it would be better to capture those strings
in order to avoid whack-a-mole in future tests. All of this points to using a
dictionary containing one or more strings-to-be-replaced values.

# Simulate an error after partial response.
if 'partialresponse' in req.form:
req.respond(200, 'text/plain')
req.write('partial content\n')
raise AttributeError('I am an uncaught error!')

setattr(webcommands, 'raiseerror', raiseerror)
webcommands.__all__.append('raiseerror')
