selector2: vendor selector2 library
This library was a backport of the Python 3 "selectors" library. It is
useful to provide a better selector interface for Python2, to address some
issues of the plain old select.select, mentioned in the next patch.
The code [1] was ported using the MIT license, with some minor modifications
to make our test happy:
1. "# no-check-code" was added since it's foreign code.
2. "from __future__ import absolute_import" was added.
3. "from collections import namedtuple, Mapping" changed to avoid direct
symbol import.

@commands in debugcommands.py should be in alphabetical order.
>>> import re
>>> commands = []
>>> with open('mercurial/debugcommands.py', 'rb') as fh:
... for line in fh:
... m = re.match("^@command\('([a-z]+)", line)
... if m:
... commands.append(m.group(1))
>>> scommands = list(sorted(commands))
>>> for i, command in enumerate(scommands):
... if command != commands[i]:
... print('commands in debugcommands.py not sorted; first differing '
... 'command is %s; expected %s' % (commands[i], command))
... break
Prevent adding new files in the root directory accidentally.
