When the host OS is Mac OS X, direct addressing in BII doesn't guarantee
that the allocated memory for frame buffer base address in the host
(FrameBaseHost) satisfies the following conditions:
- FrameBaseHost > RamBaseHost
- (FrameBaseHost - RamBaseHost) + Frame_Size < 4GiB
where RamBaseHost refers to the emulated RAM base address in the host.
This may cause the random hang problem where the allocated frame address
failed to meet the conditions above.
Because the direct addressing mapping is a simple math:
RamAddrMac = RamAddrHost - RamBaseHost.

- In 8 bit color game, the hack crashed the app.
- After backing out the hack, I can play 256 color game with displaycolordepth 8.
- By default, the displaycolordepth is 0.

By default, without providing `with-sdl2` in configure it uses SDL1.
Users need to explicitly request SDL2.

The old code used the `[[` shell keyword, which is only available in bash.
The interpreter in line 1 is `/bin/sh` though.
This confused my shell portability check in pkgsrc, since that check neither guesses the target platform from the filename, nor assumes that `/bin/sh` is actually bash, even though this may be true on macOS.
The change makes the code shorter with the well-known `${var:-default}` pattern.
Since `$1` is now only accessed when it is defined, this allows the program to have a `set -eu` at the top.
This in turn would make all the `&&` redundant since it applies automatic error checking.
The `{ ... } 1>&2` could also be replaced with a single `exec 1>&2` at the top.
- add wrappers with default calling convention for powerpc_cpu member functions used through nv_mem_fun ptr()
** explicit wrappers for member functions that were used explicitly
** dynamic wrapper generator in nv_mem_fun1_t for member functions used dynamically via the instruction table
- add missing direct addressing (non-zero constant offset to Mac memory) support in lvx and stvx implementations
- fix mismatched parameter lists between powerpc_jit member functions and the calls they get through the jit_info table to fix problems at -O2
