Refactor codebase to group the lib in one folder

[antoniovazquezblanco]

This one seems to bring no advantages along with the work but I promise it is for a good reason...

Isolation of the library code is the first step towards a nice and clean structure for packaging. We are a couple of commits away from awesome results!

I am afraid these changes (or maybe the previous ones) are breaking suscan now:

Just looked into the pkg-config flags. It is definitely the .pc file. The output of pkg-config with --cflags is:

(metalloid) % pkg-config sigutils --cflags       
-D_SU_SINGLE_PRECISION -DHAVE_VOLK -I/usr/local/include

Sigutils' include dir should be /usr/local/include/sigutils and not just /usr/local/include.

Rebased with the latest develop branch. It now includes the PC fix. Untested (will do in a moment).

It now works!
