12c84046f3 [cvar] Make cvars properly typed
This is an extremely extensive patch as it hits every cvar, and every
usage of the cvars. Cvars no longer store the value they control,
instead, they use a cexpr value object to reference the value and
specify the value's type (currently, a null type is used for strings).
Non-string cvars are passed through cexpr, allowing expressions in the
cvars' settings. Also, cvars have returned to an enhanced version of the
original (id quake) registration scheme.

As a minor benefit, relevant code having direct access to the
cvar-controlled variables is probably a slight optimization as it
removed a pointer dereference, and the variables can be located for data
locality.

The static cvar descriptors are made private as an additional safety
layer, though there's nothing stopping external modification via
Cvar_FindVar (which is needed for adding listeners).

While not used yet (partly due to working out the design), cvars can
have a validation function.

Registering a cvar allows a primary listener (and its data) to be
specified: it will always be called first when the cvar is modified. The
combination of proper listeners and direct access to the controlled
variable greatly simplifies the more complex cvar interactions as much
less null checking is required, and there's no need for one cvar's
callback to call another's.

nq-x11 is known to work at least well enough for the demos. More testing
will come.

2f9df0f05b Work around some clang parsing issues
clang has no problem with labels crossing declarations, but it can't
cope with a declaration (or end of block) just after a label.

faa98d8198 [gamecode] Use a struct for offset/count pairs
This cleans up dprograms_t, making it easier to read and see what chunks
are in it (I was surprised to see only 6, the explicit pairs made it
seem to have more).

e9e54d08c0 [gamecode] Rename func_t to pr_func_t
Even more consistency.

2df64384c1 [gamecode] Clean up string_t and pointer_t
They are both gone, and pr_pointer_t is now pr_ptr_t (pointer may be a
little clearer than ptr, but ptr is consistent with things like intptr,
and keeps the type name short).

b3909dbe4c [gamecode] Add a test for call and return
It currently fails for two reasons:
 - call's mode selection is incorrect (never updated from when there was
   only the one call instruction and the mode was encoded in operand c)
 - return should automatically restore the stack pointer to the value it
   had on entry to the function, thus allowing local values stored on
   the stack to be safely returned.

c8362c28fe [gamecode] Add tests for string ops
Does not include string concatenation because I don't feel like messing
with zone init, but all the other operators are tested (currently
failing due to bool convention)

d9d37fda47 [gamecode] Implement ruamoko opcode lookup
And get the debugger working with the new instruction set.

9d74fcc181 [gamecode] Add tests for the basic math ops
* / % %% + -

As a bonus, includes partial tests for a few extra operators. Several
things are broken at this stage, but uncommitted code is already
working.

b8d04874c3 [gamecode] Add some math tests
Hit a show stopper when it came to swizzle (not implemented yet). I
guess I know what I need to do next :P.

c86f1f671b [gamecode] Add tests for load instructions
This needed the test struct declaration to be moved out to a head file
so it can be shared with other tests.

bf604b99b3 [gamecode] Add automated tests for store ops
They even found a bug in the addressing mode functions :) (I'd forgotten
that I wanted signed offsets from the pointer and thus forgot to cast
st->b to short in order to get the sign extension)
