library cleanup

[Poul-Henning Kamp]

I did som cleanup in the varnishapi library this morning, and I want
the VMOD writers to pay a bit of attention.

VUT, VTIM, VSB, VAS and VCS are now partially exposed by libvarnishapi.

I have not exposed everything in them (yet), only the bits needed to
compile the tools in the tree (varnishlog/ncsa/...)

Should we expose all of these function sets ?

Should we also expose VPF, VSS, VSA, VTCP ?

I may also rename the SHA256 to VSHA256 in order to stick strictly
to the V* namespace...

Input, comments...
