rsc 19333efb9e Some proc cleanup, moving some of copyproc into allocproc.
Also, an experiment: use "thread-local" storage for c and cp
instead of the #define macro for curproc[cpu()].

rsc f32f3638f4 Various cleanup:
- Got rid of dummy proc[0].  Now proc[0] is init.
 - Added initcode.S to exec /init, so that /init is
   just a regular binary.
 - Moved exec out of sysfile to exec.c
 - Moved code dealing with fs guts (like struct inode)
   from sysfile.c to fs.c.  Code dealing with system call
   arguments stays in sysfile.c
 - Refactored directory routines in fs.c; should be simpler.
 - Changed iget to return *unlocked* inode structure.
   This solves the lookup-then-use race in namei
   without introducing deadlocks.
   It also enabled getting rid of the dummy proc[0].

rsc b438eff6bf Have kernel build rule create kernel.sym, which can be
used in Bochs to make breakpoint setting easier:

	load-symbols "kernel.sym"
	vb 0x8:"main0"
	c
	disasm/25 "main0"
	vb 0x8:"main0"+0x5f
	c

etc.
