- sync linuxulator:
* de-COMPAT_43-ify:
+ socket related ioctl's
This differs from -current, as the kernel ABI is different
(kern_bind() and kern_connect() free the struct sockaddr on -stable
themself, so two calls to free() are not included in this MFC).
* bug-/compatibility-fixes
* ioctl TIOCGPTN
* 1 style(9)-fix
