4f8a06ddd3 [build] Fix a pile of gcc 10 issues
gcc got stricter about array accesses, complicating progs macros, and
much better at detecting buffer overflows.

48f737ecb6 [gamecode] Tweak types in dfunction_t
Mostly minor corrections to make more sense when reading them.

a0d85e33c2 [gamecode] Rework implementation of memset*
The memset instructions now match the move* instructions other than the
first operand (always int). Probably breaks much, but fixed in next few
commits.

aa02069dd1 Add a breakpoint flag to opcodes
The progs execution code will call a breakpoint handler just before
executing an instruction with the flag set. This means there's no need
for the breakpoint handler to mess with execution state or even the
instruction in order to continue past the breakpoint.

The flag being set in a progs file is invalid.

35c9d6ee38 Make pr_obcode.c mostly thread safe
Its public data is all read-only, and once set up, its private data is
too (just don't call init in multiple threads).

66dd3ef070 Make a bunch of count things positive-only
This fixes a pile of FIXMEs, because some things should never be
negative.

And delete a couple of useless files.

dda045bf96 Do lazy computation of def sizes from type encodings
The size is calculated when needed and cached.

4b7ecdf74a Make PR_Init take an instance to initialize
This allows internal sub-systems to do per-instance initializations
without other engine systems having to know about them.

81083698a8 Move to using an in-memory form of ddef_t
This allows the VM to work with extended ddefs transparently. It seems
to have uncovered a typedef alias relocation bug, though.

4df926e531 Write extended ddef information to progs far data
I was originally going to put it in the debug syms file, but I realized
that the data persistence code would need access to both def type and
certainly correct def offsets for defs in far data.

7a399c956b Encode function parameter alignment
The encoding is 3:5 giving 3 bits for alignment (log2) and 5 bits for
size, with alignment in the 3 most significant bits. This keeps the
format backwards compatible as until doubles were added, all types were
aligned to 1 word which gets encoded as 0, and the size is unaffected.

4269c8cb07 Rename the mod instruction to rem
Because % really implements remainder rather than true modulo, and I
plan on adding %% to implement true modulo.

df7c08a010 Add support for doubles to Ruamoko
Only as scalars, I still need to think about what to do for vectors and
quaternions due to param size issues. Also, doubles are not yet
guaranteed to be correctly aligned.

The stack is for data, not return addresses.

3fb9fb9373 Attempt to autoconfiscate gcc_struct.
It seems some tool-chains get rather picky about such things.

e8721122b1 Use __attribute__((gcc_struct)) on dstatement_t.
Trust Microsoft to have really weird structure layout rules. Ah, well, this
fixes the weird progs errors Sock was getting.

6eb6b6c0ba Change pointer_t to unsigned and clean up the mess.
It doesn't make sense to have negative pointers. The size of the commit is
from enabling gcc's -Wtype-limits warning and cleaning up that mess too.

55cc0f9206 Bring back the unsigned type (PROGS version bump)
This is only low-level support (the unsigned keyword still does not work),
but sufficient to make switch statements using jump tables work.

This is a nasty commit, sorry, but 99% of the commit is interdependent.

762aefc9b1 implement Raven's calling convention (rcall: first 2 params in opb and
opc). should give a general speedup to most progs.

b35561504c do proper selector registration. unfortunatly, I discovered I'd created pr_method_t incorrectly and so had to bump the progs version again
This is an imperfect revision of history.

c3f41e3e69 new opcode: state.f. same as state, but takes a 3rd float operand to
specify the step for calculating nextthink. accessed using
[frame, think, step] (state is [frame, think])

385a90e8fb correct pr_symtab_t to include the pointer to the array of selectors used
in the module. Unfortunatly, this requires a version bump on both qfo and
progs files due to the changes structure layout.

0806fc33dd debugging improvements. opcodes now sport an optional format specifier for
printing their args (default is "%Ga, %Gb, %gc") and PR_ValueString will
try to print what a pointer points to
