Tomohiro Kusumi 8111eb4abc Fix calloc(3) arguments order
calloc(3) takes `nelem` (or `nmemb` in glibc) first, and then size of
elements.  No difference expected for having these in reverse order,
however should follow the standard.

Exclude HAVE_UIO_ZEROCOPY and HAVE_DNLC from analysis since
these macro's will never be defined until this functionality
is implemented.

Non-whitespace changes are as follows:

* 8 times ; to { } in for/while loop
* fix missing ; in cmd/zed/agents/zfs_diagnosis.c
* comment (confim -> confirm)
* change endline , to ; in cmd/zpool/zpool_main.c

Brian Behlendorf 4dad7d91e2 Remove unconditional sharetab update
Removes the unconditional sharetab update when running any zfs
command. This means the sharetab might become out of date if
users are manually adding/removing shares with exportfs.  But
we shouldn't punish all callers to zfs in order to handle that
unlikely case. In the unlikely event we observe issues because
of this it can always be added back to just the share/unshare
call paths where we need an up to date sharetab.

Michael Kjorling d1d7e2689d cstyle: Resolve C style issues
The vast majority of these changes are in Linux specific code.
They are the result of not having an automated style checker to
validate the code when it was originally written.  Others were
caused when the common code was slightly adjusted for Linux.

This patch contains no functional changes.  It only refreshes
the code to conform to style guide.

Everyone submitting patches for inclusion upstream should now
run 'make checkstyle' and resolve any warning prior to opening
a pull request.  The automated builders have been updated to
fail a build if when 'make checkstyle' detects an issue.

Gunnar Beutner 46e18b3f0f Implemented sharing datasets via NFS using libshare.
The sharenfs and sharesmb properties depend on the libshare library
to export datasets via NFS and SMB. This commit implements the base
libshare functionality as well as support for managing NFS shares.
