- Fixes#15145
A replacement listed in a new [indexed] section of textures.ini holds
palette indices instead of colors: a palette PNG (the file's palette index)
or an 8-bit grayscale PNG (the gray value), at any resolution. When the
texture is built, the indices go through the game's current CLUT, including
the CLUT index shift, mask and start position, and the result is uploaded as
an ordinary RGBA texture. A game that swaps or customizes a palette keeps
working with a high-resolution replacement.
[indexed] keys use the [hashes] format and are matched with the same
wildcards, so a key with a zero CLUT hash covers every palette of the
texture. The contents hash only covers the indices, so one image is shared
by all palettes (the loaded data is shared, each palette still has its own
texture cache entry).
Saving does not dump indexed textures yet.

Reject non-positive or oversized dimensions independently in the PNG
header peeker, matching the existing 8192 pixel decode limit. Use
checked size_t arithmetic before allocating replacement RGBA data so
crafted dimensions cannot overflow the allocation size.
pngLoadPtr allocated the decoded buffer directly from attacker-controlled
PNG IHDR dimensions with no upper bound, so browsing a crafted game icon
or savedata could trigger a multi-gigabyte allocation.
- Add maxWidth/maxHeight parameters to pngLoadPtr (default 8192x8192)
and reject images larger than the limits.
- Thread the limits through LoadTextureLevelsFromFileData,
CreateTextureFromFileData, and CreateTextureFromFile.
- Limit game icons to 256x128 in GameInfoCache and IconCache.
* Rename LogType to Log
* Explicitly use the Log:: enum when logging. Allows for autocomplete when editing.
* Mac/ARM64 buildfix
* Do the same with the hle result log macros
* Rename the log names to mixed case while at it.
* iOS buildfix
* Qt buildfix attempt, ARM32 buildfix
* Move and rename file_util/fd_util to Common/File/FileUtil and DirListing
Let's also move net while we're at it.
Move the ZIM/PNG loaders over to Common.
Move the UI framework into Common
iOS buildfix
* Buildfix
* Buildfixes
* Apple buildfix
* This typo again..
* UWP buildfix
* Fix build of PPSSPPQt, such as it is (it's not in good condition...)
* Guess what? Another buildfix.
