[RFC] errno.h: Provide EFSCORRUPTED for everybody

[Valdis Kletnieks <valdis.kletnieks@vt.edu>]

Three questions: (a) ACK/NAK on this patch, (b) should it be all in one
patch, or one to add to errno.h and 6 patches for 6 filesystems?), and
(c) if one patch, who gets to shepherd it through?


There's currently 6 filesystems that have the same #define. Move it
into errno.h so it's defined in just one place.
