Incorporated all feedback received:

- Explicitly allow people to dereference sb->buf and sb->len, and include
comments about the potential problems with doing so. Document that alloc
is probably better left unreferenced. Remove sb_len() and sb_string().
- Ensure that we grow by at least 1.5x, even if we're using slob.
- Start by allocating 128 bytes
- Pass a gfp_t to sb_printk
- Drop the bogus change to snd_ac97_proc_regs_write
- Add stringbuf.o to obj-y instead of lib-y, otherwise a fully modular kernel
might not pull in sb_printf

a retrograde step."
