[RTL]: Document and flesh out Boot Status Data (BSD) API/Structures
[NDK]: Document latest RTL_BSD_DATA as of RS3 based on ext.dll WinDBG
extension "!blackboxbsd" which outputs the entire structure field by
field :).
[NDK]: Update RTL_BSD_ITEM_TYPE thanks to ole32 symbols
[RTL]: Move system volume APIs to sysvol.c
[RTL]: Fill out BsdItemTable based on actual field offsets/sizes and not
hardcoded magic numbers which we won't ask where they came from.
[RTL]: Make RtlCreateBootStatusDataFile use an appropriate structure for
initializing the buffer instead of "UCHAR Buffer[12] = {0xC,0,0,0,
1,0,0,0, 1, 0x1e, 1, 0};" which appears like magic knowledge.
[RTL]: Rename "WriteMode" to "Read" in RtlGetSetBootStatusData
since
it's much less confusing.
[RTL]: Some formatting fixes, SAL updates.
