Add a new library to determine mime types
In order to determine file types by content rather than
extension, add a new library to autotest, magic.py, that
is based on the work of Jason Petrone. The advantage of
magic.py is that it doesn't depend on any external utility
or library. It exposes the public interface guess_type(),
that will match the data against a database of magic numbers.
Also, use the library to determine file contents on a
base_utils.py function.
Changes from v1:
* Fixed some incorrect API usage documentation
* Used optparse in the parser
* Used the library in the other places of autotest that do need
assessment of file contents.

+"""
+Library used to determine a file MIME type by its magic number, it doesn't have
+any external dependencies. Based on work of Jason Petrone (jp_py@jsnp.net),
+adapted to autotest.
+
+Command Line Usage: Running as 'python magic.py file_path' will print a
+ mime string (or just a description) of the file present on file_path.
+
+API Usage:
+ magic.guess_type(file_path) - Returns a description of what the file on
+ path 'file' contains. This function name was chosen due to a similar
+ function on python standard library 'mimetypes'.
