fc907e232f [audio] Rework alsa to use a pull model
This brings the alsa driver in line with the jack render (progress
towards #16), but breaks most of the other drivers (for now: one step at
a time). The idea is that once the pull model is working for at least
one other target, the jack renderer can become just another target like
it should have been in the first place (but I needed to get the pull
model working first, then forgot about it).

Correct state checking is not done yet, but testsound does produce what
seems to be fairly good sound when it starts up correctly (part of the
state checking (or lack thereof), I imagine).

db322ce88b [audio] Clean up snd_render.h namespace polution
There's no need for the function typedefs and the warts on the member

421421e038 [audio] Correct alsa period size calculation
and rename the variable since it's not the size of the frame (may be
from the very early days of ALSA development, and I suspect the
terminology changed a bit).

The calculation was including the bits per sample, which makes no sense
as the period size determines the number of samples in a submission
chunk (and thus latency). For now, set it to around 5.5ms (will probably
need a cvar).

097d44e270 [util] Handle double shutdown
If Sys_Shutdown gets called twice, particularly if a shutdown callback
hangs and the program is killed with INT or QUIT, shutdown_list would be
in an invalid state. Thus, get the required data (function pointer and
data pointer) from the list element, then unlink the element before
calling the function. This ensures that a reinvocation of Sys_Shutdown
continues from the next callback or ends cleanly. Fixes a segfault when
killing testsound while using the oss output (it hangs on shutdown).

2278f5e494 [gamecode] Make def type when indexing size
Fixes #12

However, this is a bit of a band-aid in that the code for global defs
seems redundant (there is very similar code a little above that is
always executed) and the code for field defs should probably be executed
unconditionally: I suspect the problem fixed by
d5454faeb7 still shows with game coded
compiled with recent versions of the compiler, I just haven't tested
any.

d23c9582f1 [qwaq] Implement execute-to-cursor
Support for finding the first address associated with a source line was
added to the engine, returning 0 if not found.

A temporary breakpoint is set and the progs allowed to run free.
However, better handling of temporary breakpoitns is needed as currently
a "permanent" breakpoint will be cleared without clearing the temporary
breakpoing if the permanent breakpoing is hit while execut-to-cursor is
running.

778c07e91f [util] Get vectors working for non-SSE archs
GCC does a fairly nice job of producing code for vector types when the
hardware doesn't support SIMD, but it seems to break certain math
optimization rules due to excess precision (?). Still, it works well
enough for the core engine, but may not be well suited to the tools.
However, so far, only qfvis uses vector types (and it's not tested yet),
and tools should probably be used on suitable machines anyway (not
forces, of course).

a461c09586 [util] Make cmem consistent on 32 and 64 bit systems
I don't know that the cache line size is 64 bytes on 32 bit systems, but
it should be ok to assume that 64-byte alignment behaves well on systems
with smaller cache lines so long as they are powers of two. This does
mean there is some waste on 32-bit systems, but it should be fairly
minimal (32 bytes per memblock, which manages page sized regions).

52168da93e [vulkan] Don't lose other sky cube faces
Because LoadImage uses Hunk_TempAlloc, the face images need to be copied

c29e9828b6 [vulkan] Clean up misuse of va for vulkan handles
The built up "path" name of the handle resource was not always surviving
the intervening call to cexpr_eval_string (in particular, when other
handles were created in the process of creating a handle). Rather than
simply increase the number of va buffers (where would it end?), just
regenerate the path when adding the new handle. It's probably quick
enough, and the code is not usually not on a critical path.

I was reading about multi-pass rendering on mobile devices

Sellers had, too, since used his Vulkan Programming Guide as a
reference). Doesn't seem to make any difference on desktop, but as
there's no loss there, but potential gains on mobile, I'd say it's a
win.

39103cc8a3 [sw] Fix some 32-bit assembly issues
I'm not sure that the mismatch between refdef_t and the assembly defines

6fea5f5e1a [build] Add -Wformat-non-literal option
While this caused some trouble for pr_strings and configurable strftime
(evil hacks abound), it's the result of discovering an ancient (from
maybe as early as 2004, definitely before 2012) bug in qwaq's printing
that somehow got past months of trial-by-fire testing (origin understood
thanks to the warning finding it).

This is for the conversion /to/ paletted textures. The conversion is

measured the difference yet, but Mr Fixit does seem to load much faster for

The server edict arrays are now stored outside of progs memory, only the

There were actually several problems: translucency wasn't using or

Light styles and shadows aren't implemented yet.

The map's entities are used to create the lights, and the PVS used to

That could do with some more improvements (eg, checking if a leaf is
outside a spotlight's cone), but the concept seems to work.

fbc1bd9f6e [renderer] Clean up entity_t to a certain extent
This is the first step towards component-based entities.

There's still some transform-related stuff in the struct that needs to
be moved, but it's all entirely client related (rather than renderer)
and will probably go into a "client" component. Also, the current
components are directly included structs rather than references as I
didn't want to deal with the object management at this stage.

As part of the process (because transforms use simd) this also starts
the process of moving QF to using simd for vectors and matrices. There's
now a mess of simd and sisd code mixed together, but it works
surprisingly well together.

PL_ParseLabeledArray works the same way as PL_ParseArray, but instead
takes a dictionary object. The keys of the items are ignored, and the
order is not preserved (at this stage), but this is a cleaner solution
to getting an array of objects when the definitions of those objects
need to be accessible by name as well.

f023675f8c [vulkan] Clean up draw's memory handling a little
Use cmem for pic and cachpic name allocations. If nothing else, it at
least keeps memory a little less fragmented.

c536a363ec [vulkan] Remove namehack.h
Never really wanted in the first place (back when I did the plugin
renderers), but I didn't feel like doing the required work to avoid it
at the time. At least with Vulkan being a fresh start in an environment
that's already plugin-friendly, there was no real work involved. I'll
get to the other renderers eventually (especially now that I know gdb
does the right thing when there are multiple functions with the same
name).

1275067655 [vulkan] Rename vulkan_framebuffer_t
It turns out I had conflated frame buffers with frames and wound up
making a minor mess when separating the number of frames the renderer
could have in flight from the number of swap-chain images. This is the
first step towards correcting that mistake.

e929dca300 [util] Auto-cast plist string items
The casting uses a recursive call to the expression parser, so the
expressions are type-checked automatically.

8179c44042 [vulkan] Rework pipeline parsing for better reuse
It's not entirely there yet, but the basics are working. Work is still
needed for avoiding duplication of objects (different threads will have
different contexts and thus different tables, so necessary per-thread
duplication should not become a problem) and general access to arbitrary
fields (mostly just parsing the strings)

d2536e584f [util] Add plist support to cexpr
This allows plist objects to be accessed directly from cexpr expressions
using struct.field syntax for dictionary objects and array[index] syntax
for array objects.

5d1d85f72e [util] Resurrect Hunk_Print and fix some errors
It turned out that Hunk_HighAlloc was not creating a hunk header
(ancient bug by me), and I cleaned up a bunch of name-size issues, along
the way.

0bfb60775e [util] Ensure hunk allocs are cache alligned
This doesn't seem to make much difference in the vulkan renderer, but it
certainly doesn't hurt.

bc7858bb87 [model] Move parent pointer out of leaf/node struct
The node struct was 72 bytes thus two cache line. Moving the pointer
into the brush model data block allows nodes to fit in a single cache
line (not that they're aligned yet, but that's next). It doesn't seem to
have made any difference to performance (at least in the vulkan
renderer), but it hasn't hurt, either, as the only place that needed the
parent pointer was R_MarkLeaves.
