/* 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.)
