Global replacement of __[su]{8,16,32,64} with [su]{8,16,32,64} and layout.h define it.

Port attribute lookup functions with attribute list support from ntfs tng driver. Port/reimplement extent mft record handling code as well. Rename out all dollar signs from type names and constants. Adapt all callers to new API. Note mkntfs is currently broken due to some needed work.

With lots of luck this is going to be 1.2.3.

It has been a long time since last commit. At moment have done a lot of work
on mkntfs but also at the moment ntfsfix and ntfsdump_logfile and libntfs are
broken. Basically only mkntfs works and that is not complete either.

Added cvs Id header.

2001/01/24 02:13:24-00:00 !antona
Add a bunch of headers (attrib.h is work in progress).
