xattr.h and xattr.c access the xattr system calls via an abstraction
layer in lib/sysxattrs.h and lib/sysxattrs.c . Instead of modifying
xattr.h and xattr.c, you should modify the abstraction layer; that will
be much easier and cleaner.
Also remember that, since Mac OS before 10.4 doesn't support arbitrarily
named xattrs, only a few {get,set}xattr calls have {get,set}attrlist
equivalents, namely those that access "com.apple.ResourceFork",
"com.apple.FinderInfo", or "com.apple.crtime96" (the rsync-specific name
for the creation time).

Without offense to its author, that patched rsync 2.5.5 looks pretty
messy, especially because all of the attributes had to be implemented
ad-hoc. Let's start from scratch and reuse the nice xattr
infrastructure present in rsync 3.0.0pre8 by making the necessary
extensions to the abstraction layer.
