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. :(

merge: also allow 'e' action with experimental.updatecheck=noconflict
With experimental.updatecheck=noconflict set, if one checks out
f3398f1f70a0 (tests: add execute bit and fix shbang line, 2015-12-22)
and then try to check out its parent, hg will complain about
conflicting changes, even though the working directory is clean. We
need to also allow the 'e' action in merge.py. The 'e' action is used
when moving to a commit where the only change to the file is to its
executable flag, so it's just an optimized 'g' action.
Doesn't seem to be worth writing a test for, since the existing setup
in test-update-branches.t does not set any flags.

osutil: fix potential wrong fd close
According to POSIX closedir [1]:
If a file descriptor is used to implement type DIR, that file descriptor
shall be closed.
According to POSIX fdopendir [2]:
Upon calling closedir() the file descriptor shall be closed.
So we should avoid "close(dfd)" after "closedir(dir)". With threads, there
could be a race where an innocent fd gets closed. But Python GIL seems to
help hiding the issue well.

bdiff: use Python memory allocator in fixws
Python has its own memory allocation APIs. For allocations
<= 512 bytes, it allocates memory from arenas. This means that
average small allocations don't call the system allocator, which
makes them faster. Also, arena allocations cut down on memory
fragmentation, which can matter for performance in long-running
processes.
Another advantage of using the Python memory allocator is that
allocations are tracked by Python. This is a bigger deal in
Python 3, as modern versions of Python have some decent built-in
tools for examining memory usage, leaks, etc.
This patch converts a trivial malloc() + free() in the bdiff code
to use the Python allocator APIs. Since the object being
operated on is a line, chances are it will use an arena. So,
this could have a net positive impact on performance (although
I didn't measure it).

branchmap: handle nullrev in setcachedata
906be86990 recently changed to switch from:
self._rbcrevs[rbcrevidx:rbcrevidx + _rbcrecsize] = rec
to
pack_into(_rbcrecfmt, self._rbcrevs, rbcrevidx, node, branchidx)
This causes an exception if rbcrevidx is -1 (i.e. the nullrev). The old code
handled this because python handles out of bound sets to arrays gracefully. The
new code throws because the self._rbcrevs buffer isn't long enough to write 8
bytes to. Normally it would've been resized by the immediately preceding line,
but because the 0 length buffer is greater than the idx (-1) times the size, no
resize happens.
Setting the branch for the nullrev doesn't make sense anyway, so let's skip it.
This was caught by external tests in the Facebook extensions repo, but I've
added a test here that catches the issue.
