We don't want to dirty any data when we're in the final txgs of the pool
export logic. This change introduces checks to make sure that no data is
dirtied after a certain point. It also addresses the culprit of this
specific bug – the space map cannot be upgraded when we're in final
stages of pool export. If we encounter a space map that wants to be
upgraded in this phase, then we simply ignore the request as it will get
retried the next time we set the fragmentation metric on that metaslab.

recv_incremental_replication() takes care of things like removing
datasets that have been removed on the sending side, detecting renamed
datasets, ensuring that all datasets in the affected hierarchy have the
same properties as their counterparts on the sending side.
All of the above are not necessary if we are receiving a stream for a
single dataset that has been generated with zfs send -p, that is, a
stream that includes properties. zfs_receive_one() already takes care
of applying the properties to the received datasets.

When a member of a RAIDZ has been replaced with a device smaller than
the original, then the top level vdev can report its expand size as
16.0E.
The reduced child asize causes the RAIDZ to have a vdev_asize lower than
its vdev_max_asize which then results in an underflow during the
calculation of the parents expand size.
Fix this by updating the vdev_asize if it shrinks, which is already
protected by a check against vdev_min_asize so should always be safe.
Also for RAIDZ vdevs, ensure that the sum of their child vdev_min_asize
is always greater than the parents vdev_min_size.

In glibc 2.5, makedev(), major(), and minor() are defined in
sys/sysmacros.h. They are also defined in types.h for backward
compatability, but using these definitions triggers a compile warning.
This breaks the ZFS build, as it builds with -Werror.
autoconf email threads indicate these macros may be defined in
sys/mkdev.h in some cases.
This commit adds configure checks to detect where makedev() is defined:
sys/sysmacros.h
sys/mkdev.h
It assumes major() and minor() are defined in the same place.
The libspl types.h then includes
sys/sysmacros.h (preferred) or
sys/mkdev.h (2nd choice)
if one of those defines makedev().
This is done before including the system types.h.
An alternative would be to remove uses of major, minor, and makedev,
instead comparing the st_dev returned from stat64. These configure
checks would then be unnecessary.
This change revealed that __NORETURN was being defined unnecessarily in
libspl/include/sys/sysmacros.h. That definition is removed.
The files in which __NORETURN are used all include types.h, and so all
will get the definition provided by feature_tests.h

spa_sync() iterates over all the dirty dnodes and processes each of them
by calling dnode_sync(). If there are many dirty dnodes (e.g. because we
created or removed a lot of files), the single thread of spa_sync()
calling dnode_sync() can become a bottleneck. Additionally, if many
dnodes are dirtied concurrently in open context (e.g. due to concurrent
file creation), the os_lock will experience lock contention via
dnode_setdirty().
The solution is to track dirty dnodes on a multilist_t, and for
spa_sync() to use separate threads to process each of the sublists in
the multilist.

In torvalds/linux@a528d35, there are changes to the getattr family of functions,
struct kstat, and the interface of inode_operations .getattr.
The inode_operations .getattr and simple_getattr() interface changed to:
int (*getattr) (const struct path *, struct dentry *, struct kstat *,
u32 request_mask, unsigned int query_flags)
The request_mask argument indicates which field(s) the caller intends to use.
Fields the caller has not specified via request_mask may be set in the returned
struct anyway, but their values may be approximate.
The query_flags argument indicates whether the filesystem must update
the attributes from the backing store.
Currently both fields are ignored. It is possible that getattr-related
functions within zfs could be optimized based on the request_mask.
struct kstat includes new fields:
u32 result_mask; /* What fields the user got */
u64 attributes; /* See STATX_ATTR_* flags */
struct timespec btime; /* File creation time */
Fields attribute and btime are cleared; the result_mask reflects this. These
appear to be optional based on simple_getattr() and vfs_getattr() within the
kernel, which take the same approach.

- A zfs_mnt_t structure was added for the sole purpose of
providing a structure to pass the osname and raw mount
pointer to zfs_domount() without having to copy them.
- Mount option parsing was moved down from the zpl_* wrapper
functions in to the zfs_* functions. This allowed for the
code to be simplied and it's where similar functionality
appears on other platforms.

Several functions were renamed when ZFS was originally ported to
Linux. Revert the code to the original names to minimize the
delta with upstream OpenZFS.
zfs_sb_teardown -> zfsvfs_teardown
zfs_sb_create -> zfsvfs_create
zfs_sb_setup -> zfsvfs_setup
zfs_sb_free -> zfsvfs_free
get_zfs_sb -> getzfsvfs
zfs_sb_hold -> zfsvfs_hold
zfs_sb_rele -> zfsvfs_rele
zfs_sb_prune_aliases -> zfs_prune_aliases (Linux-only)
zfs_sb_prune -> zfs_prune (Linux only)
Align the zfs_vnops.h and zfs_vfsops.h with upstream as much
as possible. Several prototypes were removed and those that
remain were reordered.
Move the EXPORT_SYMBOL lines to the end of the source files
for consistency with the other source files.
