Currently there is one flag:
- NO_STEAL_FOCUS
This is used in the toast daemon so toasts don't steal focus.
Other flags will be added in the future to control whether a window is
displayed when created, whether it should animate a particular way, etc.
This is a pretty big commit, so let's run through it in parts:
- All of the userspace changes are to switch away from syscall_wait
Mostly, this is to waitpid; some things were tweaked to do things
"properly" instead of waiting for particular processes. Init has
been fixed to do a proper spin wait.
- syscall_wait is gone - as are its uses. newlib bindings have been
using just waitpid for a while now.
- waitpid now performs like a Unix waitpid
- process reaping is no longer a "do this on next change thing":
it happens when a process is waited on, like it should
(That means we can have real zombies: terminated processes that
have not yet been waited on)
- Reparenting of children to init has been implemented, so you
can fork-daemonize!
Overall, this is pretty big... So I hope it doesn't break everything.
