adc30bb531 Move Std.hpp into CRT directory 
It's also been renamed to stddef.h since all it contained was the
definition of NULL, which lives in that header in a standard C library.

c020c2e247 jsrf.h scalar deleting destructors return void * 
They previously returned a pointer to the class type, but this isn't
accurate to the signature indicated by MSVC's name mangling.

It appears to be all C code (especially the non-C++ parts of the C

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.

022582003d objdiff symbol matching refinements 
With name mangling, objdiff.json no longer needs massive lists of which
names to match to what.  Some function signatures were also minorly
refined.

0e84f9ab1f Refine for virtual method check in mangling script 
We used the flimsy heuristic of a reference from non-executable memory
to try to guess at whether a reference was a vtable, but now we just
check whether it's been named as a vtable.

f193fef3ce Enable string pooling 
JSRF evidently has string pooling enabled (i.e. program-wide
deduplication of strings), so we'll want it in our compiler settings as
well.

The only stuff left in delink/ was also for using with Ghidra, so we may
as well also put it in ghidra/.

30f8a5879e Include namespace in symbol table 
This introduces its own issues, but without namespaces, symbol names end
up repeated and delinking fails.  The delinked symbols also end up
without namespaces, introducing yet more problems.  This is an
improvement for now, but we'll need proper namespace importing into
Ghidra at some point.

absolute paths:
