[Tools 1/2] winetest: Standardize handling of winetest.cgi's arguments and add prototypes.

[Francois Gouget]

The prototypes let Perl detect when the wrong number of parameters is passed to these functions.
---

Note that test_reportfile() did not actually use the parameter it was 
given. move_file() does though it could just as well use the global 
$name variable given its current usage. But just in case we find other 
uses for it later on I kept the parameter.
