status: when extracting arguments from `opts`, use the same default values

Sometimes other code, such as commit when using `commands.commit.post-status`,
calls `commands.status()` without going through the normal dispatch mechanism
that would typically fill in the args to be something besides None. As a
"defense in depth" mechanism for a bug where Mercurial would crash if both
`commands.commit.post-status` and `experimental.directaccess` were enabled,
let's sanitize these values to be identical to the values they would have when
the user invoked this method from the commandline.

cHg
===

A fast client for Mercurial command server running on Unix.

Install:

 $ make
 $ make install

Usage:

 $ chg help                 # show help of Mercurial
 $ alias hg=chg             # replace hg command
 $ chg --kill-chg-daemon    # terminate background server

Environment variables:

Although cHg tries to update environment variables, some of them cannot be
changed after spawning the server. The following variables are specially
handled:

 * configuration files are reloaded automatically by default.
 * CHGHG or HG specifies the path to the hg executable spawned as the
   background command server.

The following variables are available for testing:

 * CHGDEBUG enables debug messages.
 * CHGSOCKNAME specifies the socket path of the background cmdserver.
 * CHGTIMEOUT specifies how many seconds chg will wait before giving up
   connecting to a cmdserver. If it is 0, chg will wait forever. Default: 60

Build environment variables:

 * HGPATH: the path to the hg executable to call when CHGHG and HG are not set,
   instead of "hg"
 * HGPATHREL=1: when CHGHG and HG are not set, the hg executable will be ./hg
   relative to the chg executable. Only works on linux, falls back to "hg"
   otherwise.
