[ITA] libsigc2.0

[Philippe Baril Lecavalier]

2.10.3 (2020) -> 2.12.1 (2023)

Encountered two issues, documentation related.

1. Anything where doxygen calls dot (graphviz), it just hangs, forever, 
no message. Looked at rebuilding graphviz and doxygen, tried a few 
things, no simple fix. It seems to be a known issue with other packages, 
applying this quick fix: Just toggle off any HAVE_DOT from Doxygen file.

2. It proposes to build a pdf optionally. If we make a doc package, why 
not (I see they didn't bother with the pdf on Gentoo, not even an 
option). I might have the reason... annoying docbook dependencies and 
dblatex went on an infinite loop (missing a font dependency), also no 
message. Annoying... Therefore proposed this upstream, so that it fails 
cleanly in the future:
