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.

-Because \fBSMB\fR shares requires a resource name, a unique resource name is constructed from the dataset name. The constructed name is a copy of the dataset name except that the characters in the dataset name, which would be illegal in the resource name, are replaced with underscore (\fB_\fR) characters. A pseudo property "name" is also supported that allows you to replace the data set name with a specified name. The specified name is then used to replace the prefix dataset in the case of inheritance. For example, if the dataset \fBdata/home/john\fR is set to \fBname=john\fR, then \fBdata/home/john\fR has a resource name of \fBjohn\fR. If a child dataset of \fBdata/home/john/backups\fR, it has a resource name of \fBjohn_backups\fR.
