Subject: Stackless HTML rendering

Now that every node has a parent pointer, it's possible to implement
the HTML rendering functions without render stacks and any dynamic
memory allocations.

This commit also adds some minor optimizations that eliminate some
strbuf_put* calls for the common case and avoid printf for headers.
