This uses the virtual /proc filesystem to identify when the user runs
`python` without redirecting stdout/stdin. If this is the case, we run
`python -i` instead. Otherwise, or if there are arguments, we run it

Revert of Removed virtualenv from depot_tools (patchset #1 id:1 of https://codereview.chromium.org/1437483002/ )

Reason for revert:
This CL over-aggressively removed the Windows bootstrap code used by /gclient.bat, which in turn downloads/installs the Windows toolchain, including Python. Labs can no longer provision Windows bots because of this.

update_depot_tools.bat did more than initialize the virtualenv. It also downloaded and installed Python, Git, and Subversion on Windows systems.

I'm reverting to restore the toolchain so we can create new Windows bots.

Patch contributed by Leung Wing Chung <lwchkg@gmail.com>.
Committed on his behalf due to Commit Queue's mishandling of
CRLF files.

Here is my procedure for testing for a new install

1. Download and unzip
   https://src.chromium.org/svn/trunk/tools/depot_tools.zip
   Note that the path should include a space character,
   e.g. "with a space"

2. Copy the three modified files to the unzipped folder

3. Convert the unzipped files into Windows CRLF.

4. REMOVE the following lines from update_depot_tools.bat
   (Should I file a separate bug for this?)

:: Initialize/update virtualenv.
cd /d "%DEPOT_TOOLS_DIR%."
python -u bootstrap\bootstrap.py --deps_file bootstrap\deps.pyl --quiet ENV
if errorlevel 1 goto :EOF

5. Run gclient. Installation should be okay until
   "git rebase" is run.
