Right now most of the dart SDK's python is compatible with python2
or python3. This change fixes a few of the build scripts to make
that completely true (at least when building the standard build on
Linux). There are only four types of changes:
- Bare `print` statements now use the `print ()` function
- `commands.getoutput` becomes `subprocess.check_output` with `shell=True`
- `xrange` becomes `range`
- `print >> sys.stderr` becomes `sys.stderr.write`
Starts work on addressing (but does not completely fix):

This change applys to both the `dev` and `master` branches.

This CL computes the correct input and output in the copy_tree GN template by
modifying tools/copy_tree.py to perform a dry-run that lists the files to be copied.
Also, shutil.copytree uses shutil.copy2 to copy files and their metadata, but copying
the metadata appears to confuse ninja dependency tracking.
To do the dry run and to use shutil.copy instead of shutil.copy2, copy_tree.py now
uses its own CopyTree function instead of shutil.copytree.
