According to PEP263 (http://www.python.org/peps/pep-0263.html

) the source code
encoding, like the magic comment '-*- coding: utf-8 -*-', must be on the two
first lines. If not, default encoding is ascii and SyntaxError will be raised
if there is a non-ASCII character.

We use current locale to convert argv to unicode and handle it as uncode after.

If we have to format (aka interpolatation) we need to be sure this have to be
done in unicode and not in ascii. This avoid unicode error with ascii string
encoded in utf-8.

Example of failure between a string and an object

b = Exception(u"é")
Exception("error: %s" % b)
 => Exception("error: %s" % str(b)
 => UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 0: ordinal not in range(128)

This function walk across a directory, for every template which match the
extension, remplace by the rendered file with the same mode/uid/gid as the
template file.
Use jinja2 as template engine.

Before this, timeout only apply to repository caching.

Now timeout is used by all transfert functions.
A new parameter repo_timeout is available to set a custom timeout on repository

In case of bad download, error given by is feeder is better than output
of compressor which claims data are missing

We now use system tar and gzip to compress/decompress payloads

Goals are:
- Speed-up extraction and creation of payloads.
- Allow to use non-python supported compressor like (pbzip2 and xz)
- Remove python2.7.1 tarfile.py module
- Remove python 2.7.1 gzip.py to avoid filename to be in gzip headers
- Remove gzipstream.py module used to stream gzip file
