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

282132958f Relocate local def type encodings in debug load 
For technical reasons (programmer laziness), qfcc does not fix up local
def type encodings when writing the debug symbols file (type encoding
location not readily accessible).

4bc36836a1 Correct the type of an aux function's return type 
It was made to be the address of the type encoding long ago.

89e83d7d73 Move the debug info out of progs_t 
The debug subsystem now uses the resources system to ensure it cleans
up, and its data is now semi-private. Unfortunately, PR_LoadDebug had to
remain public for qfprogs because using PR_RunLoadFuncs would cause
builtin resolution to complain.

ca6fe0730b Fix qfcc test harness tracing 
Just a consequence of progs execution state being initialized properly.

6739f5df4d Fix an out-by-one error 
Noticed while sorting out pr_argc

a55b9544ac Improve handling of pr_argc 
It is now set to 0 when progs are loaded and every time
PR_ExecuteProgram() returns. This takes care of the default case, but
when setting parameters, pr_argc needs to be set correctly in case a
vararg function is called.

61d7f4f9c4 Dump locals stack when dumping main stack 
Any shutdown functions in progs will need locals too.

6a4ef598ab Allow progs num_edicts and reserved_edicts to be null 
Really, while there are edict related instructions, edict support should
probably not be in the VM itself.

6e56c9a4aa Ensure edict_parse is reset on progs load 
A server switching from a game that sets edict_parse to one that does
not could go badly when it comes time to loading a level.

9bb68f2d8c Allow nested use of PR_SaveParams() 
PR_SaveParams() is required for implementing the +initialize diversion
used by Objective-QuakeC because builtins do not have local def spaces
(of course, a normal stack calling convention would help). However, it
is entirely possible for a call to +initialize to trigger another call
to +initialize, thus the need for stacking parameter stashes. As a
bonus, this implementation cleans up some fields in progs_t.

256dee98a1 Make progs string resources management private 
Strangely enough, using the progs resources system. This is a step
towards having progs that can be reset properly, or even dynamically
created VMs.

3720956d88 Speed up two of the three deletion cases 
The initial code was pretty much a port of the code in the editor I
wrote 25 years ago. Either I didn't think of the optimization back then,
or I tried to implement it, failed, and figured it wasn't worth it
(despite using it on a 386dx33). However, I noticed it now and it was
easy enough to get working, and it's always good to not do something
that's not needed.

27ae5ccfce Fix ICE after incomplete type error 
Attempting to define a variable with an incomplete type is an error, and
results in a default size 1 of allocated, but I forgot to set default
alignment when implementing alignment.

81293d98dd Fix qfo line info dumping 
The addition of xdef data has made qfo_to_progs unusable in qfprogs,
resulting in various invalid memory accesses. It always was an ugly hack
anyway, so this is the first step to proper qfo support in qfprogs.
