* Port previous ethernet scheme * Add ipd * Fix initfs rebuilds, use QEMU user networking addresses in ipd * Add tcp/udp, netutils, dns, and network config * Add fsync to network driver * Add dns, router, subnet by default * Fix e1000 driver. Make ethernet and IP non-blocking to avoid deadlocks * Add orbital server, WIP * Add futex * Add orbutils and orbital * Update libstd, orbutils, and orbital Move ANSI key encoding to vesad * Add orbital assets * Update orbital * Update to add login manager * Add blocking primitives, block for most things except waitpid, update orbital * Wait in waitpid and IRQ, improvements for other waits * Fevent in root scheme * WIP: Switch to using fevent * Reorganize * Event based e1000d driver * Superuser-only access to some network schemes, display, and disk * Superuser root and irq schemes * Fix orbital
