Tweak the wix configs to actually build a 64bit installer.
unfortunately this breaks the 32bit msi without edits to the Setup.2015
WiX configs for the 32bit temp pathes. We are looking for a solution for
this.
The new C compiler breaks a lot of things. snprintf and timespec now exist, and redefining causes an error.
Many more things are warnings, so warnings-as-errors will fail - remove it from some projects for now.
V8: don't pass VS version to build batch file.
mod_sofia: Config has too-long if/elseif chain. Break this up to avoid "parser stack overflow; program too complex".
Add mod_conference.h to project and dir to includes.
