* Fixed building using system utf8proc
* Fixed building using system portaudio
* Allow using system-wide asio headers (1.11.0 or higher required).
* Allow using system-wide glm headers
* Allow using system-wide rapidjson headers
* create derived 6502 type for XaviX because it has at least one custom 4-byte opcode that doesn't fit any other type.
treating that opcode as NOP for now.
have a feeling it might be something to do with the other integrated hardware, might be 'execute co-processor code chain at this address' or something similar
It isn't a standard JSL (Jump Subroutine Long) like the SNES cpu opcode in the same place as this, it seems to point at some code-like structures tho)
could also be a secondary operation mode with different encoding like ARM's Thumb mode tho I guess.
We currently only have a single XaviX based dump (taitons1) but there are more on the way. I'm going to see if the code flow makes any sense at all with these missing, or if any of it gives a clue as to what they should actually do.
* xavix - let's call these callf and retf then
after further investigation these are some kind of extra 'long jump' subroutine / task handlers, the 0x80 also being a custom opcode was throwing me off trying to identify them before.
looks like they might have been hacking 65816 features into the regular 6502 core?

please people, remember to keep source UTF-8 and if you're committing on behalf of others, clean up indents to meet MAME conventions
anyone can run srcclean over a submission and see what will get hit
An implementation of the National Semiconductor DP8510 BITBLT Processing Unit. This is used on the InterPro GT family graphics boards, and this implementation seems to be correct enough to enable me to progress there, hence the PR. While I'd love to have another system to test against, I'm not aware of any other systems that ever used this device other than some NatSemi reference designs, which are not (yet) in MAME.
