debuginstall extension support

  $ hg debuginstall --config extensions.fsmonitor= --config fsmonitor.watchman_exe=false | grep atchman

  fsmonitor checking for watchman binary... (false)

   watchman binary missing or broken: warning: Watchman unavailable: watchman exited with code 1

Verify the json works too:

  $ hg debuginstall --config extensions.fsmonitor= --config fsmonitor.watchman_exe=false -Tjson | grep atchman

    "fsmonitor-watchman": "false",

    "fsmonitor-watchman-error": "warning: Watchman unavailable: watchman exited with code 1",

Verify that Mercurial is installable with pip. Note that this MUST be

the last test in this file, because we do some nasty things to the

shell environment in order to make the virtualenv work reliably.

On Python 3, we use the venv module, which is part of the standard library.

But some Linux distros strip out this module's functionality involving pip,

so we have to look for the ensurepip module, which these distros strip out

completely.

On Python 2, we use the 3rd party virtualenv module, if available.

  $ cd $TESTTMP

  $ unset PYTHONPATH

#if py3 ensurepip

  $ "$PYTHON" -m venv installenv >> pip.log

Note: we use this weird path to run pip and hg to avoid platform differences,

since it's bin on most platforms but Scripts on Windows.

  $ ./installenv/*/pip install --no-index $TESTDIR/.. >> pip.log

    Failed building wheel for mercurial (?)

Note: --no-site-packages is deprecated, but some places have an

ancient virtualenv from their linux distro or similar and it's not yet

the default for them.
