/* decode_instructions -- dump a range of addresses as native instructions
   This implements the protocol required by the HotSpot PrintAssembly option.

   The start_va, end_va is the virtual address the region of memory to
   disasemble and buffer contains the instructions to decode,
   Disassembling instructions in the current address space is done by
   having start_va == buffer.

   The option string, if not empty, is interpreted by the disassembler implementation.

   The printf callback is 'fprintf' or any other workalike.
   It is called as (*printf_callback)(printf_stream, "some format...", some, format, args).

   The event callback receives an event tag (a string) and an argument (a void*).
   It is called as (*event_callback)(event_stream, "tag", arg).

   Events:
     <insn pc='%p'>             begin an instruction, at a given location
     </insn pc='%d'>            end an instruction, at a given location
     <addr value='%p'/>         emit the symbolic value of an address

   A tag format is one of three basic forms: "tag", "/tag", "tag/",
   where tag is a simple identifier, signifying (as in XML) a element start,
   element end, and standalone element.  (To render as XML, add angle brackets.)
