URL module

[Jose E. Marchesi]

Hi Giuseppe.

What do you think about making an 'url' gnulib module containing the
(adapted) code from src/url.[ch] in wget?  Such a module would ease the
management of urls in both libraries and programs.  It is not funny to
link with libcurl just because you need to escape a url string, for
example.

The code in url.[ch] seems to be quite independent from the rest of the
codebase.
