Some of the functions' purpose wasn't immediately obvious without
additional explanations. This commit adds these missing comments.

This should simplify the code a bit by re-using existing code
to fork and exec a process.

Issue #190
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.

Closes#341
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.
