Extracted games contain a boot.bin file that contains the disc header.
These boot.bin files are considered valid volumes by Dolphin, since
Dolphin only checks the disc header to determine if something is a valid
GC/Wii disc. Running them doesn't make any sense, though.
boot.bin files used to not be scanned by Dolphin due to their file
extension, but .bin was added to the list of file extensions to scan for
in 494e2c0. To stop them from showing up in the game list, let's update
the ShouldHideFromGameList mechanism.
In PPCTables.cpp, the code is currently unused so I was unable to test it.
In CustomPipeline.cpp, a pointer to member function cannot be used due to 16.4.5.2.1 of the C++ Standard regarding "addressable functions". https://eel.is/c++draft/namespace.std#6
In Fs.cpp and DirectoryBlob.cpp, these examples used projections in a previous iteration of this commit, but no longer do. Still, they remain in this commit because the PR they would actually belong to is already merged.
In LabelMap.cpp, the code is currently unused so I was unable to test it.
In WiiUtils.cpp, the magic value `1u` was replaced by the constant value `DiscIO::PARTITION_UPDATE`.
A deep-copy method CopyReader has been added to BlobReader (virtual) and all of its subclasses (override). This should create a second BlobReader to open the same set of data but with an independent read pointer so that it doesn't interfere with any reads done on the original Reader.
As part of this, IOFile has added code to create a deep copy IOFile pointer onto the same file, with code based on the platform in question to find the file ID from the file pointer and open a new one. There has also been a small piece added to FileInfo to enable a deep copy, but its only subclass at this time already had a copy constructor so this was relatively minor.
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.
