836b5eaa41 Incorporate known names from Smilebit code 
The Yakuza 1 and 2 rereleases on the Wii U export function symbols,
preserving their names, and some debug data was also available in a PS2
release, providing some struct definitions.  These have been used to
rename analogous classes, functions, and member variables to the same
names used by Smilebit, plus a more general imitation of their naming
and typing conventions (i.e. Win32 style).

709bbf9a54 Default to __cdecl for name mangling 
It's definitely ideal for everything to be declared explicitly, but it
would require either manual intervention or a new dedicated script to do
this for typedefs (that aren't methods), so we'll do this as the least
worst option.

a2b777d666 Disable function thunking when importing 
Thunked functions can confuse the delinker extension into thinking that
multiple symbols have the same name and lead to delinking failures (with
no diagnostic, conveniently).

That is, xapi0.obj, which has been renamed from crt0.obj because it
appears to be part of the Xbox libraries rather than the C runtime.

9b6c91a12e Prevent repeated name mangling 
A symbol could be encountered more than once in headless mode if it
appeared in the body of a function.  The mangler script now tracks which
symbols have been seen to avoid this.

bbe9d63294 Update documentation for new scripts 
This includes the enhanced export/import scripts and the class fixup
script (with the name mangler being used implicitly).  With this, the
switchover from simple label-based sharing of Ghidra project information
to rich type and class information is complete.

84c165a0af Complete basic build process 
We now have generation of an import library for linking against the Xbox
kernel, linking together an .exe, and converting it to an .xbe via cxbe.
Some further development of tooling aside (including filling in some
features in cxbe to better match the original JSRF executable), all that
remains now is to write decompiled code.

ccd2cd37a5 Defend against spurious references during mangling 
Ghidra sometimes identifies random numbers as pointers, which trips up
our mangler script when it encounters them as they generally have no
type information.  We now use heuristics to ignore such references.
