MIN and MAx are macros that a developer will universally expect
throughout the source. Yet, they were being defined in multiple places
across the source. Instead, define them in a single location in the
common wget.h header file and use them consistently everywhere.
This commit makes lots of whitespace only changes. It has been ensured that this

This is a relatively large commit that implements two major features:
1. Implement --show-progress switch to force the display of the progress bar in
any verbosity level
2. Edit the implementation of the progress bar so that the filename is displayed
in the same line.
When accessing a URL using IDN which directly redirects to another page,
wget would xfree_null(iri->orig_url); in src/retr.c:retrieve_url()
first, then later xfree_null(iri->orig_url); in src/iri.c:iri_free()
again.
This can be tested with wget -O /dev/null http://μφ.net
