This patch introduces changes to support current OS X (10.10 Yosemite).
The previous OS X code base is about 4 years old and both OS X and
XFS changed, so there had to be done some work to make it compilable.
- xfs_repair currently has only a dummy timer implementation
- fsr and io, as tools working with a mounted XFS, are
really not expected to work - lots of dummy functions
- Various other edits - some API translations, some missing
defines.
The code compiles using Apple's clang, although it throws some
warnings. Some of them are complaints about deprecated calls, some
are false-positives and there are also some incompatible type
assignments/comparisons. Fixing these looks like an ugly work,
but fortunately, incompatible assignments are only in the tools
not expected to work anyway (fsr and io).
