[Libguestfs] [PATCH nbdkit 3/6] common/include/minmax.h: Remove MIN3/MAX3 macros.

[Richard W.M. Jones]

These were added to support the checkwrite filter, but the original
change didn't work on platforms that lack __auto_type, resulting in an
additional hack.  However as part of changing checkwrite to use
nbdkit_extents_full these macros (and hack) are no longer needed, so
remove them.

Updates: commit acaa3db5b39759d9e7e65f4e5ef10a5383e50b29
Updates: commit 2d0954dd6431cfd8d82e873a5b99285b0fddbeb8
