another directory rename: failstar -> fail

Browse Source 
"failstar" sounds like a name for a cruise liner from the 80s.  As "*" isn't a
desirable part of directory names, just name the whole thing "fail/", the core
parts being stored in "fail/core/".

Additionally fixing two build system dependency issues:
 - missing jobserver -> protomessages dependency
 - broken bochs -> fail dependency (add_custom_target DEPENDS only allows plain
   file dependencies ... cmake for the win)

PERFORMANCE
===========
Optimize functions in util-nexus.c: mon_memzero, mon_memcpy, mon_memset
They could be done a lot more efficiently.
Perhaps make mon_memzero function specifically for pages.
Pseudo devices and special guest-OS specific device drivers for
disk/network/video/etc and an associated architecture. This would
let us pass data more quickly and prevent a lot of emulation overhead.
The real device emulation could plug into the same architecture as
the pseudo devices.
Fix extra CR3 reload in nexus.S
Alignment of routines in mon-fault.c
