68b4255a96 runtime: ,s/[a-zA-Z0-9_]+/runtime·&/g, almost 
Prefix all external symbols in runtime by runtime·,
to avoid conflicts with possible symbols of the same
name in linked-in C libraries.  The obvious conflicts
are printf, malloc, and free, but hide everything to
avoid future pain.

The symbols left alone are:

	** known to cgo **
	_cgo_free
	_cgo_malloc
	libcgo_thread_start
	initcgo
	ncgocall

	** known to linker **
	_rt0_$GOARCH
	_rt0_$GOARCH_$GOOS
	text
	etext
	data
	end
	pclntab
	epclntab
	symtab
	esymtab

	** known to C compiler **
	_divv
	_modv
	_div64by32
	etc (arch specific)

Tested on darwin/386, darwin/amd64, linux/386, linux/amd64.

Built (but not tested) for freebsd/386, freebsd/amd64, linux/arm, windows/386.

d9c989fa25 various: avoid %ld etc 
The Plan 9 tools assume that long is 32 bits.
We converted all instances of long to int32 when
importing the code but missed the print formats.
Because int32 is always int on the compilers we use,
it is never correct to use %lux, %ld, etc.  Convert to %ux, %d, etc.

(It matters because on 64-bit gcc, long is 64 bits,
so we were printing 32-bit quantities with 64-bit formats.)
