Add ListFonts, SetFontPath, and GetFontPath protocol builders to proto/x11.py and a regression test that reproduces the doListFontsAndAliases stack buffer overflow. The test creates a temporary font directory with a fonts.alias file containing an alias whose target name is 400 bytes -- exceeding the old XLFDMAXFONTNAMELEN of 256 but under libXfont2's MAXFONTNAMELEN of 1024. It prepends this directory to the font path via SetFontPath, then sends ListFonts matching the alias name. Without the fix, the server would copy the oversized resolved name into a 256-byte stack buffer, causing a stack buffer overflow.
