7fb335a215 [vulkan] Add support for building and loading shaders
Shaders can be built as spv files and installed into
$libdir/quakeforge/shaders or as spvc files and compiled into the
engine. Loading supports $builtin/name to access builtin shaders,
$shader/path to access external standard shaders and quake filesystem
access for all other paths.

80aec45e35 [vulkan] Ensure msaa settings are consistent
I had forgotten that msaa samples was governed by the driver (as a max)
and the renderpass setup code simply took the max. Thus why 1 vs 8
caused the display to render incorrectly.

79f22ffebf [util] Propagate cexpr errors back to the caller
Not much point in error detection when it's ignored.

ac8206555e [vulkan] Get the parsed pipeline working
It turned out the msaa setting defaulting to 1 instead of 8 was the
problem no idea why at this stage (need to read up on just how that
setting works). Once I understand just how it works, I'll rework the
msaa handling.

96df447c45 [vulkan] Hook up the expression parser
The pipeline parser still isn't hooked up yet as something isn't quite
right, but it seems all the parsing works.

4649294a27 [util] Fix inferred binary operator type checking
The problem is that I needed to support dynamic types on operators (for
bit-field enums), had things working, but a bad edit messed things up
and I had to rebuild that bit of code. Missed one bit :P

f3682638d4 [util] Add a mini expression parser
It is capable of parsing single expressions with fairly simple
operations. It current supports ints, enums, cvars and (external) data
structs. It is also thread-safe (in theory, needs proper testing) and
the memory it uses can be mass-freed.

591667c36d [util] Add a context parameter to the plist parsers
Not used by the dict/array parsers themselves, but is passed on to any
value parser callbacks for their own use.

ebcef5c8a4 [util] Deal with gcc optimizing out isnan checks
This occurs because of -ffast-math, but I need to investigate how much
of an impact disabling it has on QF's performance.

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.

af814ff9a8 [util] Add a cache-line aligned memory allocator
This was inspired by
Hoard: A Scalable Memory Allocator
  for Multithreaded Applications

 Emery D. Berger, Kathryn S. McKinley, Robert D. Blumofe, Paul R.
 Wilson,

It's not anywhere near the same implementation, but it did take a few
basic concepts. The idea is twofold:
1) A pool of memory from which blocks can be allocated and then freed
en-mass and is fairly efficient for small (4-16 byte) blocks
2) Tread safety for use with the Vulkan renderer (and any other
multi-threaded tasks).

However, based on the Hoard paper, small allocations are cache-line
aligned. On top of that, larger allocations are page aligned.

I suspect it would help qfvis somewhat if I ever get around to tweaking
qfvis to use cmem.

62f3e1f428 [util] Calculate quaternion to rotate between two vectors
The calculation fails (produces NaN) if the vectors are anti-parallel,
but works for all other combinations. I came up with this implementation
when I discovered Unity's Quaternion.FromToRotation could did not work
with very small angles. This implementation will produce a usable
quaternion below 0.00255 degrees (though it will be slightly larger than
unit). Unity's failed such that I could see KSP's skybox snap while it
rotated around my test vessel.

e991c44232 [util] Make a minor improvement to QuatMultVec
Switch from using addition to multiplication for doubling the value.

Also, fix lib/util/test Makemodule to actually work (too much c&p
coding).

62c20aa4ab [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.

optionally not parsing strings and better utf-8 and wide char handling.

f4c8d341e1 [vulkan] Implement most of the parser
This gets renderpass parsing almost working (not hooked up, though). The
missing bits are support for expressions for flags (namely support for
the | operator) and references (eg $swapchain.format). However, this
shows that the basic concept for the parser is working.

16c6818612 [util] Set parsed array size correctly
The array has to be allocated using byte elements and thus the size of
the array is the number of bytes, but it needs to be the actual number
of elements in the array. Problem caused by not knowing the actual type
(and C not having type variables anyway).

0945f30731 [vulkan] Use a property list to drive code gen
The property list specifies the base structures for which parser code
will be generated (along with any structures and enums upon which those
structures depend). It also defines option specialized parsers for
better control.

7a478b4ce7 [libr] Make PLItem more useful
I can't say that I like what's there even now, but at least PLItem can
be used without a lot of casting. Really, Ruamoko needs dictionary and
string classes so reading a property list can build more natural object
trees rather than this mess from when I knew too little.

225ee0ed3c [qwaq] Use an actual condition variable for control
I think I wasn't sure at the time whether the simple variable was
required for pthread_cond_wait (and friends) to work properly, but it
is: the time between the target posting the debug event and the target
waiting on the condition variable turns out to sometimes be enough for
the debugger to handle the event and signal the target to continue,
resulting in the target waiting on a signal that will never come because
another debug event will not be sent by the target until AFTER it has
exited from the debug handler.

1910941426 [qwaq] Handle key events differently when running
Pressing F8 (or n) while the debug target was running would cause it to
stop at that point. While it's certainly desirable to stop a runaway
target on demand, that should be with a different input. Now, commands
that start the target running are ignored while the target is running.
No commands for when the target is running have been implemented yet,
but the provision is there.

2ca9f80d56 [vulkan] Split up vkgen
It worked as a proof of concept, but as the code itself needs to be a
bit smarter, it would be a lot smarter to break up that code to make it
easier to work on the individual parts.

8bd5f4f201 [util] Add code to parse a dictionary to a struct
PL_ParseDictionary itself does only one level, but it takes care of the
key-field mappings and property list item type checking leaving the
actual parsing to a helper specified by the field. That helper is free
to call PL_ParseDictionary recursively.
