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.

Previously all the functions took two arguments: src, dst. This is the
reverse of the usual Go style and worth changing sooner rather than
later.

Unfortunately, this is a change that the type system doesn't help
with. However, it's not a subtle change: any unittest worth the name
should catch this.

CAST5 is the default OpenPGP cipher.

(This won't make Rob any happier about the size of crypto/, of course.)

It already has dst, src in that order but it doesn't have any users yet so I figure it's better than changing it later.

There's no need to hold the client mutex when calling encode, since encode itself
uses a mutex to make the writes atomic.  However, we need to keep
the messages ordered, so add a mutex for that purpose alone.

First step towards a more light-weight implementation of token.Position:
- only use token.Position for reporting token and error position
- use offsets only for scanner control
- no interface changes yet
