dir_path is used by PanicAlertFormatT, which prior to PR 10209 used a
lambda. Before c++20, referring to structured bindings in lambda captures
was forbidden. The problem is now doubly fixed, so put the structured
binding back in.
This command does not upload the MAIN buffers to CPU memory. This was
functionally fixed in f11a40f858 without
updating the comments and variable names.
Prior to 7854bd7109, this was used by the debugger for the OpenGL and D3D9 plugins to control logging (via PRIM_LOG and INFO_LOG/DEBUG_LOG in VideoCommon code; PRIM_LOG was changed in 77215fd27c), and also framedumping (removed in 64927a2f81 and 2d8515c0cf), shader dumping (removed in 2d8515c0cf and this commit), and texture dumping (removed in 54aeec7a8f). Apart from shader dumping, all of these features have modern alternatives, and shader source code can be seen in RenderDoc if "Enable API Validation Layers" is checked (which also enables source attachment), so there's no point in keeping this around.
Previously, we had WBFS and CISO which both returned an upper bound
of the size, and other formats which returned an accurate size. But
now we also have NFS, which returns a lower bound of the size. To
allow VolumeVerifier to make better informed decisions for NFS, let's
use an enum instead of a bool for the type of data size a blob has.
For a few years now, I've been thinking it would be nice to make Dolphin
support reading Wii games in the format they come in when you download
them from the Wii U eShop. The Wii U eShop has some good deals on Wii
games (Metroid Prime Trilogy especially is rather expensive if you try
to buy it physically!), and it's the only place right now where you can
buy Wii games digitally.
Of course, Nintendo being Nintendo, next year they're going to shut down
this only place where you can buy Wii games digitally. I kind of wish I
had implemented this feature earlier so that people would've had ample
time to buy the games they want, but... better late than never, right?
I used MIT-licensed code from the NOD library as a reference when
implementing this. None of the code has been directly copied, but
you may notice that the names of the struct members are very similar.

Needed for the next commit. NFS disc images are hashed but not encrypted.
While we're at it, also get rid of SupportsIntegrityCheck.
It does the same thing as old IsEncryptedAndHashed and new HasWiiHashes.
This normalization was added in 02ac5e95c8, and changed to use floats in 4bf031c064. The conversion to floats means that sometimes there is insufficient precision for the normalization process, which results in values of NaN or infinity. Performing the whole process with doubles prevents that, but games also sometimes set the values to NaN or infinity directly (possibly accidentally due to the values not being initialized due to them not being used in the current configuration?).
The version of Mesa currently in use on FifoCI (20.3.5) has issues with NaN. Although this bug has been fixed (b3f3287eac in 21.2.0), FifoCI is stuck with the older version.
This change may or may not be incorrect, but it should result in the same behavior as already present in Dolphin, while working around the Mesa bug.
CARDUCode, GBAUCode, and INITUCode previously didn't have an implementation of it. In practice it's unlikely that this caused an issue, since these uCodes are only active for a few frames at most, but now that GBAUCode doesn't have global state, we can implement it there. I also implemented it for CARDUCode, although our CARDUCode implementation does not have all states handled yet - this is simply future-proofing so that when the card uCode is properly implemented, the save state version does not need to be bumped. INITUCode does not have any state to save, though.
The accuracy improvements are:
* The request mail must be 0xabba0000 exactly; both the low and high parts are checked
* The address is masked with 0x0fffffff
* Before, the global state meant that after the GBA uCode had been used once, it would accept 0xcdd1 commands immediately. Now, it only accepts them after execution has finished.
These lookup tables total 4 megabytes, and contain data that's entirely redundant to the actual cache state (as part of an optimization, though I'm not sure whether the optimization actually is useful). This change instead recomputes these lookup tables when loading the state (which involves filling the lookup table with a marker (0xff), and then setting the 128 * 8 valid entries (1 kilobyte)).
