Ran "2to3 -w -n -f print ./" and manually added imports.
Ran "^\s*print " and "\s+print " to find batch/shell scripts, comments and the like with embedded code, and updated them manually.
Also manually added imports to files, which used print as a function, but were missing the import.

The scripts still work with Python 2.
There are no intended behaviour changes.

gclient_utils.py is a kitchen sink and is for that reason expensive
to import. Move the comparatively cheap and simple path routines
to a new gclient_paths module and use that in gn.py, clang_format.py,
dart_format.py.

(To be able to move FindGclientRoot() to gclient_paths.py,
make it use io.open() instead of FileRead(). FileRead() tries
to paper over invalid utf-8, but that was added for presubmits,
not for .gclient files, so this is hopefully fine.)

Cuts gn.py overhead in half (on my Windows laptop from 0.6s to 0.25s,
still high; on my Mac laptop from 0.1s to 0.05s), and probably helps
the other two too.

Completely remove PathDifference() since it's unused.

This is neccessary to ensure that generated ninja commands invoke python from
PATH instead of the one from VPython's VirtualEnv. On LUCI builders that replace
system python with VPython using vpython:native-python-wrapper swarming tag, a
new VPython VirtualEnv bubble will be created for each script and contain that
script's individual dependencies.

Handle KeyboardInterrupt gracefully rather the printing a
backtrace. Most users of these tools don't expect a
backtrace when then hit Ctrl-C.

Also, fix a few other inconsistencies found in the python
startup code of these different scripts:
- always call main function 'main' (rather than 'Main')
- always return 0 from main function
- if main takes args never include argv[0]

In https://codereview.chromium.org/341533006/ a change
was made so that gn.py is not looking for the .gn file
to identify the root of the checkout. This breaks
GN functionality for projects that uses gclient but
have a top directory named something else than 'src'.

This change adds support for arbitrarily named primary (the first)
solutions in the .gclient file.
It also adds a check for the generated GN path so a friendly
error message can be printed if the GN executable cannot be found.

The gn binary itself is capable of being run from outside of a
checkout as long as you pass the --root flag.

However, the gn.py wrapper script needs to *also* know where the the
checkout is, in order to figure out how to find the gn binary itself.

This patch changes the wrapper to be aware of the --root arg :).

as part of the Chromium checkout.

This follows the approach used by gn.

Changes include:
 - in-the-PATH clang-format trampoline scripts
 - clang_format.py, which finds clang-format binaries inside of Chrome
 - Hook 'git cl format' to the new binaries and scripts
 - Rearrange some code, for reuse between clang_format.py and gn.py

This automatically searches the path for a source root (or takes one from the
command line), and then executes the current platform's GN binary inside that
source tree.

This will allow the user to have a "gn" command on their path, and allow our
scripts to run GN without having to bake-in the logic for finding the correct
platform's GN binary.
