libzfs is the only user of libshare, and only internally, so there's no particular reason to build it separately, nor to export its symbols. So, pull it into libzfs proper, remove its "public" header, and hide its symbols. The bare minimum "public" API is just to count and enumerate the supported share types. These are moved to libzfs.h with the other share API.

# Shown below is a simplified dependency graph of the OpenZFS provided
|
|
# libraries. Administrative commands (`zfs`, `zpool`, etc) interface with
|
|
# the kernel modules using the `libzfs.so` and `libzfs_core.so` libraries.
|
|
# These libraries provide a stable ABI across OpenZFS point releases.
|
|
#
|
|
# The `libzpool.so` library is a user space build of the DMU and SPA layers
|
|
# used to implement debugging tools (zdb) and code validation tools (ztest).
|
|
# These library interfaces are subject to change at any time.
