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.

645fb9cc21 Implemented sharing datasets via SMB using libshare
Add the initial support for the 'smbshare' option using the
existing libshare infrastructure.  Because this implementation
relies on usershares samba version 3.0.23 is required.

d2e032ca9c Add 'fsid' mount option to allowed options.
Resolves nfs-utils-1.0.x compatibility issue which requires
that the fsid be set in the export options.

  exportfs: Warning: /tank/dir requires fsid= for NFS export

590338f63e Added comments for libshare's NFS functions.
Some of the functions' purpose wasn't immediately obvious without
additional explanations. This commit adds these missing comments.

ddd0fd9ef6 Use libzfs_run_process() in libshare.
This should simplify the code a bit by re-using existing code
to fork and exec a process.

5333eb0b3b Call exportfs -v once for NFS shares.
At the moment we call exportfs -v every time we check whether an
NFS share is active. This happens every time you run a zfs or
zpool command, making them extremely slow when you have a lot of
exports. The time taken is approx O(n2) of the number of shares.

This commit stores the output from exportfs -v in a temporary file
and use this to speed up subsequent accesses.

This mechanism is still too slow - if you have tens of thousands
of NFS shares it will still be painful running ANY zfs/zpool
command.

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.
