Subject: 9p: Move a couple xattr functions to 9p-util
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=ec70b956fddf628ee2e42521c54362e80115a3c4;p=qmiga%2Fqemu.git

9p: Move a couple xattr functions to 9p-util

These functions will need custom implementations on Darwin. Since the
implementation is very similar among all of them, and 9p-util already
has the _nofollow version of fgetxattrat, let's move them all there.
