2007-08-21	ARGMAX -> MAXARGS	rsc

2007-08-21	remove namelen parameter	rsc

2007-08-21	remove dead code	rsc

2007-08-21	Various cleanup:	rsc
	- 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].

2007-08-14	ide_write unused => gone	rsc

2007-08-14	Gcc expects to be able to pick up the return	rsc
	address off the stack, so put one there for it. (Bug was hidden by bad segment limits.)
2007-08-14	Because limit gives the address of the last addressable	rsc
	byte in the segment, the limit argument to SEG16 and SEG needs to have 1 subtracted from it.
2007-08-14	ditto	rsc

2007-08-14	Cannot use "g" as an arg constraint because	rsc
	some memory references aren't actually valid and gcc is a bit too smart in parsing (%0) and a bit too dumb in knowing which memory refs are not valid. Using "r" seems to constrain gcc to use a register as in (%eax) and not substitute a memory reference like (-36(%ebp)). No one really understands these things.
