Improve documentation of register constraints.

While looking at PR target/64532- I realized we haven't documented all
the register constraints. I'm not documenting the other immediate
constraints as it is not clear to me how much of that is actually
useful yet and I don't have the time this afternoon to clean this up.

Built documentation and looked at it.

Applied.

net: Restore earlier Solaris-specific version of setKeepAlivePeriod.

The version from the master repository seems to be appropriate
for OpenSolaris but not for Solaris itself.  Solaris 11.2
proper does not define TCP_KEEPIDLE or TCP_KEEPINTVL.
