The 'zpool resilver' command requires that the resilver_defer
feature is active on the pool. Unfortunately, the check for
this was left out of the original patch. This commit simply
corrects this so that the command properly returns an error
in this case.

Currently, it is possible for the 'zpool scrub' command to
progress slightly beyond 100% due to concurrent changes
happening on the live pool. This behavior is expected, but
the userspace code for 'zpool status' would subtract the
expected amount of data from the amount of data already
scrubbed, resulting in a negative integer being casted to a
large positive one. This number was then used to calculate
the estimated completion time, resulting in wildly wrong
results. This code changes the behavior so that 'zpool status'
does not attempt to report an estimate during this period.

The size argument of snprintf(3) in glibc and snprintf() in Linux
kernel includes trailing \0, as snprintf(3) man page explains it as
"write at most size bytes (including the trailing null byte ('\0'))",
i.e. snprintf() can just take buffer size.
e.g. For snprintf() in module/zfs/zfs_ctldir.c, a buffer size is
MAXPATHLEN, and a caller is passing MAXPATHLEN to snprintf(), so size
should just be `path_len` to do what the caller is trying to do.

This patch fixes 2 issues with the DMU free throttle implemented
in dmu_free_long_range(). The first issue is that get_next_chunk()
was calculating the number of L1 blocks the free would dirty
incorrectly. In some cases involving extremely large files, this
code would greatly overestimate the number of effected L1 blocks,
causing excessive calls to txg_wait_open(). This patch corrects
the calculation.
The second issue is that the free throttle uses the total number
of free'd blocks in all (open, quiescing, and syncing) txgs to
determine whether to throttle. This causes large frees (such as
those created by the first issue) to cause 4 txg syncs before
any further frees were allowed to proceed. This patch ensures
that the accounting is done entirely in a per-txg fashion, so
that frees from a given txg don't affect those that immediately
follow it.

Detect in autoconf whether `-lintl` and possibly `-liconv` are necessary
for translation functions like `gettext()`.
The actual autoconf code is just:
```
AM_ICONV
AM_GNU_GETTEXT([external])
LIBS="$LIBS $LTLIBINTL $LTLIBICONV"
```
References:
https://www.gnu.org/software/gettext/manual/html_node/AM_005fGNU_005fGETTEXT.htmlhttps://www.gnu.org/software/gettext/manual/html_node/AM_005fICONV.html
The reason to check for `libiconv` and add it separately is that this is
sometimes necessary if users are linking statically.
The `config/*.m4` files were added by running `gettextize` and removing
everything else.
The empty file `config/config.rpath` is necessary to avoid an error with
some versions of autotools, see:
http://ramblingfoo.blogspot.com/2007/07/required-file-configrpath-not-found.html
The `config.rpath` copied by `gettextize` does not currently work, there
is some kind of missing interaction with `libtool` and it tries to apply
`libtool` flags to the compiler.

zfs.8 correctly said that GRUB did not support them, but
zpool-features.5 said that "Booting off pools...is supported." Now,
zpool-features.5 discusses GRUB specifically and indicates its lack of
support for these features. Also, I have clarified the wording in both
places to indicate that the pool feature cannot be used. It's not a
filesystem dataset thing, but pool-wide.
I described this as "cannot be used". I think technically the feature
can be enabled, just not active. However, the effect is essentially the
same: you cannot enable those checksum algorithms on any dataset in the
pool, so you might as well not enable the feature (which is just
pointing a loaded gun at your foot). In the past, an argument could be
made that having all the features enabled was useful for simplicity, as
long as you didn't activate the GRUB-incompatible features, but that's
getting less and less realistic over time. A user can still do that,
but we should not encourage that.

The ZPL_VERSION could be bumped, but that would likely be handled in a
similar way, by adding filesystem feature flags. In any event, we do
not need this comment, and we certainly don't need a reference to the
