732ea3a5fd Fix a bunch of issues for clang
One *actual* error (wrong enum type), and some memory alignment issues.
The rest just clang being lame.

78a0075be1 [gamecode] Plug a nasty buffer overflow
This one is ancient: the code was essentially unmodified since release
(just some formatting). Malformed vectors could sneak through due to map
bugs (eg, "angles -90" instead of "angle -90" as in ad_tears) and the
vector parsing code would continue past the end of the string and
writing into unowned memory, potentially messing up the libc allocation
records. Replacing with the obvious sscanf works nicely.

Sometimes, Quake code is brilliant. Other times, it's a real face-palm.

978d0306c0 [hash] Rename the publicly visible hashlink_t to hashctx_t
I think my biggest problem with the hashlink freelist parameter was how
much implementation it exposed in just the name.

a31ff3153c [gamecode] Fail gracefully on invalid entity strings
Returning null (and printing some error messages) is far friendlier than
aborting.

6d62e91ce7 [gamecode] Clean up progs data access
pr_type_t now contains only the one "value" field, and all the access
macros now use their PACKED variant for base access, making access to
larger types more consistent with the smaller types.

db8cf68ef3 [gamecode] Pass registered data pointer to builtins
This is the bulk of the work for recording the resource pointer with
with builtin data. I don't know how much of a difference it makes for
most things, but it's probably pretty big for qwaq-curses due to the
very high number of calls to the curses builtins.

Closes #26

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).

cd30408675 [gamecode] Rename ev_quat to ev_quaternion
I much prefer the full name, though the short version is easier to type.

cfe7c44df0 [gamecode] Rename ev_integer to ev_int
And other related fields so integer is now int (and uinteger is uint). I
really don't know why I went with integer in the first place, but this
will make using macros easier for dealing with types.

be474d9937 [gamecode] Remove the wart from def and function names
I never liked the leading s_ (though I guess it means one is supposed to
interpret the int as a string pointer, but meh).

66fda1fddb Rewrite edict access.
The server edict arrays are now stored outside of progs memory, only the
entity data itself (ie data accessible to progs via ent.fld) is stored in
progs memory. Many of the changes were due to code accessing edicts and
entity fields directly rather than through the provided macros.

a3c1b2e992 [util] Rename qfplist.[ch]
The name is a hold-over from before the current quakeforge tree and the
QF include directory.

ab04a1915e [build] Fix a pile of gcc 10 issues
gcc got stricter about array accesses, complicating progs macros, and
much better at detecting buffer overflows.

d60291a73e Clean up a lot of va usage
va is not thread-safe (it's not save even without threads), and I want
to be able to run progs in threads.

4c1b6ce76c Make pr_parse thread safe
Or at least, conversion to property list is thread safe.

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.

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.

4c6478c77f Strip trailing spaces from field names.
A certain mod (glare at rogue) has a space at the end of a field name in
the bsp entity data causing a crash. Thanks to ccr for the report.

7c1d9d2b84 Make the angle and light hacks optional.
I'd forgotten that ED_ConvertToPlist mangled light into light_lev and
single component angle values into a vector. This fixes much of the
breakage in qflight (but not the light levels)

675db274a6 Use Sys_Error instead of PR_Error in ED_ConvertToPlist.
ED_ConvertToPlist is now independent of the progs engine as its only use
for the progs_t * param was for PR_Error.

7d2e938d37 Correct some error messages.
ED_ParseEntity has been ED_ConvertToPlist for a long time now.

e27d7cbd2d Handle alloca "correctly".
Use AC_FUNC_ALLOCA and the #ifdef mess suggested by the autoconf docs
(hidden in qfalloca.h).

6b97967a68 Use g instead of e for the fp values.
Need to up the precision by one due to the difference between g and e, but
much prettier. Might need to rename that function :P I wish I'd thought to
check if g would work, but thanks to divVerent for the suggestion.

b096a0242e Write fp values to saved games with enough precision.
That is, enough precision to uniquely identify the fp values. No drifts!

3e2a40684c Use dstring in PR_UglyValueString().
I should have done this a long time ago:P. This removes the really silly
255 char limit from strings in saved games (and thus fixes books in ITS).

6e0907a6b1 Delay the "too many entities" check.
Rather than checking the raw edict count in the entities file against the
progs' max_edicts, check the allocated entity's number. This allows loading
of sophisticated maps (eg, digs04) that prune many of their entities.

ac1bf2a158 Don't save unnamed fields.
There will normally be only one unnamed field (if any), and it's always the
null field. This will put an eventual end to the "'' is not a field"
messages.

It's pretty useless in git.

b5019c8e33 Nuke the engine dicrectory from gamecode.
Not the contents, of course :) Anyway, finally, that totally useless
directory is gone.
