dfa5893d4f preparation for exec.
* syscall:
	add syscall.RawSyscall, which doesn't use sys.entersyscall/sys.exitsyscall
	add syscall.dup2
	add syscall.BytePtrPtr
	add syscall.Rusage, RusagePtr
	add syscall.F_GETFD, F_SETFD, FD_CLOEXEC

cb67a8324b - fine-tuning of white space
- by default consider extra newlines in src for better formatting
- additional flags for control (-newlines, -maxnewlines, -optsemicolons)
- don't print ()'s around single anonymous result types

Status: Comparing the output of pretty with the input for larger files
shows mostly whitespace/formatting differences, which is what is desired.

TODO:
- Handling of overlong lines
- some esoteric cases which look funny

37bdd3c3f5 - enabled comment printing by default
- changed tab width to 8 chars by default to make test run properly
- excluded 4 files that are not idempotently printed
- fixed a couple of incorrect file position recordings in parser
- fine-tuned layout engine
- white-space formatting reasonable, but not perfect
- no handling of overlong lines
R=r

To use with smaller tabs:           pretty -tabwidth=4 file.go
To use with blanks instead of tabs: pretty -usetabs=0 file.go

d79f687ed8 - collect addition source position information in parser
for end of declarations, blocks, parameter lists, etc.
- use extra src positions to more accurately print comments
- fine-tuned low-level printing routine for comments
- added better debugging support

Status:
- comments now appear at the right place (inbetween the right tokens)
- newline control needs improvement (not very hard)
- comment printing disabled for now because pretty is not idempotent
with it; to enable: -comments

efc86a74e4 change meaning of $GOMAXPROCS to number of cpus to use,
not number of threads.  can still starve all the other threads,
but only by looping, not by waiting in a system call.

fix darwin syscall.Syscall6 bug.

fix chanclient bug.

delete $GOMAXPROCS from network tests.

add stripped down printf, sys.printhex to runtime.
