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.

addresses block.

92aa94d776 [ruamoko] Fix incorrect clearing of dtables
The problem was caused by passing the index into the dtables array to
dtable_get which expects a handle. A handle is the ones-compliment
negative of the index which means that handle 0 is invalid (but 0 was
being passed... oops). Fixes the segfault when qw-client-x11 connects to
a server.

params.

6d5ffa9f8e [build] Move to non-recursive make
There's still some cleanup to do, but everything seems to be working
nicely: `make -j` works, `make distcheck` passes. There is probably
plenty of bitrot in the package directories (RPM, debian), though.

The vc project files have been removed since those versions are way out
of date and quakeforge is pretty much dependent on gcc now anyway.

Most of the old Makefile.am files  are now Makemodule.am.  This should
allow for new Makefile.am files that allow local building (to be added
on an as-needed bases).  The current remaining Makefile.am files are for
standalone sub-projects.a

The installable bins are currently built in the top-level build
directory. This may change if the clutter gets to be too much.

While this does make a noticeable difference in build times, the main
reason for the switch was to take care of the growing dependency issues:
now it's possible to build tools for code generation (eg, using qfcc and
ruamoko programs for code-gen).

df89e37afc [console] Call PR_RunPostLoadFuncs
This fixes the segfault when loading the menu progs. I had forgotten
that the menu code doesn't use PR_LoadProgs (I don't remember why.
Obsolete reason?).

7ae047654b [util] Rework SEB affine/convex testing
When I ported SEB to python, I discovered that I apparently didn't
really understand the paper's description of the end condition and the
usage of the affine and convex sets for center testing. This cleans up
the test and makes SEB more correct for the cases that have less than 4
supporting points (especially when there are less than 4 points total).

54f2e417dc [ruamoko] Fix daft str_str abi
Returning a string was a bad idea as it makes str_str difficult to use
with str_mid. (actually, iirc, it was the only reason I moved all
strings into progs memory... hmm).

c09f57c39e [gamecode] Delay .ctor calls if debugging
This allows a debugger to do any symbol lookups and other preparations
between loading progs and the first code execution. .ctors are called as
per normal if debug_handler is not set.

535a2363bb [ruamoko] Create a va_copy for progs
In testing variable fw/precision in PR_Sprintf, I got a nasty reminder
of the limitations of the current progs ABI: passing @args to another QC
function does not work because the args list gets trampled but the
called function's locals. Thus, the need for a va_copy. It's not quite
the same as C's as it returns the destination args instead of copying
like memcpy, but it does copy the list from the source args to a
temporary buffer that is freed when the calling function returns.

a7956c7311 [gamecode] Move format state into a state struct
This is the first step in reworking PR_Sprintf to use a state machine.
The goal is to make it more robust against errors and easier to extend
(eg, * width and precision).

b4874f7d9b [gamecode] Make PR_FreeString a little more forgiving
It treats only strings that are actually invalid as invalid. That is,
now it is safe to "free" a static string: it's just a no-op.

2d5df34234 [gamecode] Add VM enter/exit events
And rename prd_exit to prd_terminate (the idea is the host will
terminate the VM). This makes it possible for the debugger to pause the
VM before any code, even a builtin function, is executed. Breaks the
debugger source window, but only because it's not updating on file
change (I think).

Bill Currie
1bd8e2ee85 [gamecode] Add a param pointer to debug_handler
I decided I want events for VM enter/exit but enter needs to somehow
pass the function which will be executed (even if a builtin). A generic
void * param seemed the best idea, which meant the error string could be
passed via the param instead of a "global" string in the progs struct.

4cef9792f4 [util] Make hash-tables semi-thread-safe
They take a pointer to a free-list used for hashlinks so the hashlink
pools can be per-thread. However, hash tables that are not updated are
always thread-safe, so this affects only updates. progs_t has been set
up such that it is easy for multiple progs within one thread can share
hashlinks.

713150b41a [gamecode] Add debug hooks to the VM engine
While there was a breakpoint hook, it was for only breakpoints and more
was needed. Now there's a generic hook that is called for tracing,
breakpoints, watch points, runtime errors and VM errors, with the
"event" type passed as the first parameter and a data pointer in the
second.
