pvr: Fix pvr_dma_transfer overriding callback data of ongoing transfer
The pvr_dma_transfer() would override the callback data, stored in
global variables, before even checking that no transfer was ongoing.
Address that by moving the place where the variables are set after the
DMA available check.
And while we're at it, disable interrupts to avoid races between
parallel calls of pvr_dma_transfer().

commit 1cbb414fb78a0bbee8db333e1fb1afe496d99a01
Author: Paul Cercueil <pa...@cr...>

pvr: Fix dma_next_list() racing with itself
The very first call to dma_next_list() does not run in an interrupt
context, nor does it run with the IRQs disabled.
As soon as pvr_dma_load_ta() is called, it is therefore possible to have
dma_next_list() re-entered from within the DMA complete interrupt
handler. This is fine, as long as we make sure that the function does
not do anything after this point that could race with the interrupt
handler.
One possible race was with the DMA complete interrupt firing before the
"pvr_state.lists_dmaed" was updated, in which case the interrupt handler
wouldn't get the updated value, or when the interrupt was firing in the
middle of updating the "pvr_state.lists_dmaed".

commit 2277c213500bad618d88a5676289cbaca7c8158f

pvr: Simplify dma_next_list()
Move the initialization of "b" before the loop.
Remove commented DBG() macros.
Replace the loop break by a "return" since nothing else will be executed
after that. This means that the "did" variable can be dropped.

commit 285beb0c3e43ffebde707577ec73ba8424456209

Added support for more queries to sysconf(). (#924)
sysconf() is an incredibly useful POSIX utility which gets used by a
LOT more software than I think we realize. I just noticed that our
upcoming SDL2 port is using it to properly return a bunch of HW queries
like available RAM.
I did notice, however, that we didn't support querying for cache
configuration and a few other things, so I added them.

Fix type clash in vmu example.
A strange side-effect from #870 . Now math.h is being
included via kos.h which caused the static y1 in vmu.c
to clash with the defined `double y1(double)` function
from math.h.
Corrected this by both restricting the headers being included
and renaming the variable.
Not quite sure how this doesn't cause problems elsewhere...

Revert alignas change to fix toolchain
commit 6505375f04621494fbec1fa2e5db4b685a9802f8

Added thread attribs to cont_btn_callback worker.
1) When using the cont_btn_callback() mechanism, a new thread is
created, which is left unnamed. This looks kind of janky and
confusing when seen in the thread listing when dumping thread info or
after an exception.
- Added a default label to the worker thread to identify it
2) By far, the most commonly implemented callback with this mechanism
tends to be some absolutely trivial logic like a simple call to
exit(0). Because of this, games which are low on RAM are typically
paying an exuberantly high amount of memory overhead just to call one
function with a default stack size of 32KB for the worker.
- Added a default stack size of 8KB, which can be overridden at
compile-time, consistently with how other default thread sizes can
be overwritten.

Fixed build issue in irq.c.
irq_get_handler() was changed from returning a single function pointer
to the old handler to return a function pointer/userdata pair with the
new API, but this return statement hadn't been updated.
- Updated to return a pair of NULL pointers for the callback struct.

mmu: Add mmu_page_map_static()
This function reserves one TLB entry to create a static mapping from a
virtual memory address to a physical memory address. Static mappings are
never flushed out of the TLB, and are sometimes useful when the whole MMU
function is not necesary. Static memory mappings can also use different page
sizes.

Make irq_cb_t a public type and return it in handler accessors.
This now allows for chaining of handlers by retrieving the full
handler/userdata set. That way when you install your own you can
choose to call the previous one within it.

Clear Timer Interrupts in the default handler.
Split from #618 . The existing behavior meant that
aside from within an installed general handler,
the TMU underflow bit would always be cleared prior
to calling its assigned handler.
It didn't really make sense as the actual handler
would then not be able to use this info. Instead,
like for TMU0, handlers are installed to all 3
which just perform this timer clear. Each of the
replacement handlers used internally already also
clear as well.
This might impact 3rd party handlers if they
presumed that the timer will have always been
cleared first.
Also some whitespace cleanup.

environ.sh: Enable fast-math by default
We recommend -ffast-math everywhere, and everyone seems to be using it.
Those who don't, probably don't need the full IEEE compliance and just
forgot to add the flag.
Note that the previous comment suggested that FSQRT was not used without
fast-math, but this was wrong. GCC will still emit that instruction in a
"fast path" when it knows it can use it, or a call to the C sqrtf()
otherwise.

environ.sh: Enable -mfsrra -mfsca unconditionally
The FSRRA and FSCA instructions will not be used by GCC unless
-ffast-math is enabled. Therefore we can move them to the
environ_dreamcast.sh script, and leave the -ffast-math option in the
main environ.sh script.

Drop vec3f ASM
Use the vec3f_t type defined by the header, and replace all inline ASM
with C code.
Apart from the "fipr" instruction, which we already have macros for,
there is absolutely no reason to have these algorithms in ASM. Not only
it is unnecessary, it is also harmful as the C compiler cannot
re-organize those instructions as it sees fit.

+RELEASE NOTES for 2.2.0
+-----------------------
+A significant change has been made regarding the default floating-point ABI used
+by KallistiOS. In previous KOS releases, and even in commercial games released
+during the Dreamcast's lifetime, the `m4-single-only` floating-point ABI was
+used. With the `m4-single-only` ABI, the SH4 CPU is always in single-precision
+mode and all uses of 64-bit `double` values are truncated to 32-bit `float`
+values by the compiler, allowing the compiler to use twice the number of
+floating-point registers at the expense of precision. Going forward, KOS now
+uses the `m4-single` floating-point ABI by default. With the `m4-single` ABI,
+the SH4 CPU is in single-precision mode upon function entry, but the compiler
+can change the mode and use true 64-bit `double` values within functions. For
+most projects, there are no implications from this change other than gaining
+the ability to use 64-bit `double` values. There are, however, two possibilities
+for negative effects:
+
+- In older projects using `double` values (which were actually being truncated
+ to 32-bit `float` values upon compilation anyway), the code should be changed
+ to explicitly use `float` values instead. If not changed, fewer floating-point
+ registers may be available to the compiler, in exchange for a needless bonus
+ doubling of floating-point precision.
+
+- The order of floating-point register names is changed. When using
+ `m4-single-only`, register names are ordered fr4, fr5, fr6, fr7, etc., but in
+ `m4-single`, register names are ordered fr5, fr4, fr7, fr6, etc. In order to
+ account for this difference and still have inline assembly functions using
+ floating-point registers work properly regardless of the ABI used, the
+ KOS_FPARG(n) macro has been provided in `arch/args.h`.
+
+Despite the change to `m4-single` by default, KOS is still committed to full
+support for `m4-single-only` in addition to offering new support for
+`m4-single`. This is selectable using the `KOS_SH4_PRECISION` environment
+variable within environ.sh. It is highly recommended to compile KOS, all
+kos-ports, and all libraries with the same uniform setting as your projects.
+Other ABIs, such as `m4` or `m4-nofpu`, are not supported at this time.

+A simple legally distinct block stacking puzzle game using raylib and kallistios that runs on the sega dreamcast.
+
+Anyone is free to do whatever they want with the code in this project.
+
+## Purpose of this Repository
+This is a block stacking puzzle game created using raylib following [this tutorial](https://www.youtube.com/watch?v=wVYKG_ch4yM) by youtuber "[Programming With Nick](https://www.youtube.com/@programmingwithnick)". I wanted to create a game for the sega dreamcast and get it running on actual hardware, but don't actually have any real experience with dreamcast homebrew development or C/C++ development, so this repository is going to show my whole learning process.
+
+I have decided to continue past the tutorial in order to further develop my skills and make a nicer Raytris experience. You can see this [here](https://github.com/Niisoks/Tetris-RayLib4DC). If you are here _just_ to see what the tutorial looks like on kallistios, [please check the branch titled "TutorialCompletion"](https://github.com/Niisoks/Tetris-RayLib4DC/tree/TutorialCompletion).
