When Wget retrieves a file through FTP, it first downloads a .listing
file and parses it for information about the files and other metadata.
Some servers may serve invalid .listing files. This patch checks for one
such known inconsistency wherein multiple lines in a listing file have
the same name. Such a filesystem is clearly not possible and hence we
eliminate duplicate entries here.

Wget was susceptible to a symlink attack which could create arbitrary
files, directories or symbolic links and set their permissions when
retrieving a directory recursively through FTP. This commit changes the
default settings in Wget such that Wget no longer creates local symbolic
links, but rather traverses them and retrieves the pointed-to file in
such a retrieval.
The old behaviour can be attained by passing the --retr-symlinks=no
option to the Wget invokation command.
Add (lots) of documentation for various parts of the test suite in the
form of Python docstrings. Also, clean up some of the redundant code and
fix indentation issues.
The server_conf hook and the server_sett() methods were no longer
required. The server configuration is currently being done by
server_conf() method in the server.
Some command line switches are passed to Wget unconditionally. These
switches should exist in a single place instead of being redundantly
defined in each test file. We add the following two switches by default
here:
1. --debug: This causes wget to be most verbose and output a lot of
debugging information. Hence, if a test fails, the test log should
provide valuable information.
2. --no-config: Users may have their own wgetrc files on the system.
However, for the tests, we want Wget to run with vanilla settings.
Hence, disbale loading any config files.
