I've attached my version of an osdep_get_name() function to get the active
function name on Solaris.
I'm only using it on OpenSolaris snv_124 x86 so far; hopefully it will
work on Solaris 10 as well, given that all of the interfaces it uses are
standard.
tcgetpgrp() returns ENOTTY if it's called on a tty other than the caller's
controlling tty, but issuing the TIOCGPGRP ioctl directly works.
TIOCGPGRP works only on the slave end of a pty pair, but since
tmux provides only the master to osdep_get_name(), and the tty argument is
an empty string (?), I'm calling ptsname() to get the slave and open it.
This should be improved somehow, but I'm not sure how right now. Either
tmux could keep a file descriptor to the slave around, or perhaps there's
some STREAMS trick that would make it work on the master end; I don't know.
