py3: call codecs.escape_decode() directly

hgwebdir: add support for explicit index files
This is useful for when repositories are nested in --web-conf, and in the future
with hosted subrepositories. The previous behavior was only to render an index
at each virtual directory. There is now an explicit 'index' child for each
virtual directory. The name was suggested by Yuya, for consistency with the
other method names.
Additionally, there is now an explicit 'index' child for every repository
directory with a nested repository somewhere below it. This seems more
consistent with each virtual directory hosting an index, and more discoverable
than to only have an index for a directory that directly hosts a nested
repository. I couldn't figure out how to close the loop and provide one in each
directory without a deeper nested repository, without blocking a committed
'index' file. Keeping that seems better than rendering an empty index.
ui: move configlist parser to config.py
The list parser is complex and reusable without ui. Let's move it to
config.py.
This allows us to parse a list from a "pure" config object without going
through ui. Like, we can make "_trustusers" calculated from raw configs,
instead of making sure it's synchronized by calling "fixconfig"s.
tests: allow ModuleNotFoundError in addition to ImportError
My environment (Python version? PYTHONPATH? something else?) raises
ModuleNotFoundError in test-check-py3-compat.t. This patch allows any
"*Error". The error string contains "error importing", so it seems
specific enough even after.
pager: avoid shell=True on subprocess.Popen for better errors (
issue5491)
man(1) behaves as poorly as Mercurial without this change. This cribs
from git's run-command[0], which has a list of characters that imply a
string that needs to be run using 'sh -c'. If none of those characters
are present in the command string, we can use shell=False mode on
subprocess and get significantly better error messages (see the test)
when the pager process is invalid. With a complicated pager command
(that contains one of the unsafe characters), we behave as we do today
(which is no worse than git manages.)
I briefly tried tapdancing in a thread to catch early pager exits, but
it's just too perilous: you get races between fd duping operations and
a bad pager exiting, and it's too hard to differentiate between a
slow-bad-pager result and a fast-human-quit-pager-early result.
I've observed some weird variation in exit code handling in the "bad
experience" case in test-pager.t: on my Mac hg predictably exits
nonzero, but on Linux hg always exits zero in that case. For now,
we'll work around it with || true. :(
