Instead of having to maintain manually the map file for LD with the list of
symbols that we want to keep in the WRaster library (the purpose is to hide
internal symbols), this patch implements a script that parses the public
API header and extracts automatically the list of names that are supposed
to be visible to the user.
The goal is to reduce possible human errors, like for example the function
RCombineAlpha that was forgotten from the list, yet still keep the map file
feature which is considered a good practice (it reduces the risk for name
clash and the risk of mis-use of internal stuff from the library).

Currently, there is no WUtil.pc file so that WINGs developers can use
pkg-config to compile programs using the WINGs utility library. This patch
fixes this, and such a file is created by make, just like WINGs.pc and
wrlib.pc.
In addition, the WUtil.pc file has been added to .gitignore and included in
the debian libwings-dev package.
The previous rule was to ignore the whole directory, while still having
some files tracked inside.
Now we only explicitly ignore the files that have been placed there by the
autotools, so we can have a better view of it in Git when adding stuff.

It helps to understand why a file is present in this file, which
in turn can help to understand where a file comes from and it makes
updates to the file easier
