[VFS] Device now exposes name, attributes, component name max length.
[VFS] Fix STFS device to return 0x200 sector size. XCTD compression
userland code appears to always expect a sector size of 0x200.
[Kernel] Move X_FILE_*_INFORMATION structs to new files.
[Kernel] Move NtQueryInformationFile, NtSetInformationFile,
NtQueryVolumeInformationFile to new file.
[Kernel] Cleanup implementation of NtQueryInformationFile,
NetSetInformationFile, NtQueryVolumeInformationFile.
[Kernel] Properly validate arguments to NtQueryInformationFile,
NetSetInformationFile, NtQueryVolumeInformationFile.
[Kernel] Properly implement query of XFileFsVolumeInformation.
[Kernel] Properly implement query of XFileFsSizeInformation.
[Kernel] Properly implement query of XFileFsAttributeInformation.
This should make it easier to find files and (in the future) split things
up into separate libraries.
It also changes around emulator initialization to make it a little more
difficult to do things out of order and a little more sensible as to when
real init work happens.
Also adding a skeleton audio system/driver and reworking CPU register
access to be more extensible.
