Boolean option to enable/disable SIGIO handlers is set by the first
of these found:
- UseSIGIO option is set in xorg.conf ServerFlags
- Default set at build time by ./configure --enable-use-sigio-by-default
- Platform default value: Solaris = no, all others = yes
This matches the current settings on all platforms except Solaris.
This reverts Solaris (for now) to the settings used in Xorg 1.6, before
SIGIO support for Solaris was added, due to some system level bugs that
won't be resolved in time for Xorg 1.7 release, but allows us to enable
when those are resolved (or when we need to test if they're resolved).
