 /* 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.)
