docs/interop: Convert qmp-spec.txt to rST

Convert the qmp-spec.txt document to restructuredText.
Notable points about the conversion:
 * numbers at the start of section headings are removed, to match
   the style of the rest of the manual
 * cross-references to other sections or documents are hyperlinked
 * various formatting tweaks (notably the examples, which need the
   -> and <- prefixed so the QMP code-block lexer will accept them)
 * English prose fixed in a few places
