4.10 compat - BIO flag changes and others
[bio] The req_op enum was changed to req_opf. Update the "Linux 4.8 API"
autotools checks to use an int to determine whether the various REQ_OP
values are defined. This should work properly on kernels >= 4.8.
[bio] bio_set_op_attrs() is now an inline function and can't be detected
with #ifdef. Add a configure check to determine whether bio_set_op_attrs()
is defined. Move the local definition of it from vdev_disk.c to
blkdev_compat.h for consistency with other related compability shims.
[bio] The read/write flags and their modifiers, including WRITE_FLUSH,
WRITE_FUA and WRITE_FLUSH_FUA have been removed from fs.h. Add the new
bio_set_flush() compatibility wrapper to replace VDEV_WRITE_FLUSH_FUA
and set the flags appropriately for each supported kernel version.
[vfs] The generic_readlink() function has been made static. If .readlink
in inode_operations is NULL, generic_readlink() is used.
[zol typo] Completely unrelated to 4.10 compat, fix a typo in the check
for REQ_OP_SECURE_ERASE so that the proper macro is defined:
s/HAVE_REQ_OP_SECURE_DISCARD/HAVE_REQ_OP_SECURE_ERASE/
