smbd: add create_conn_struct_cwd()

Browse Source 
Compared to create_conn_struct_tos_cwd() this takes a TALLOC_CTX and
tevent_context as additional arguments and the resulting connection_struct is
stable across the lifetime of mem_ctx and ev.

/********************************************************
Fake up a connection struct for the VFS layer.
This takes an TALLOC_CTX and tevent_context from the
caller and the resulting connection_struct is stable
across the lifetime of mem_ctx and ev.
Note: this performs a vfs connect and changes cwd.
See also the comment for create_conn_struct_tos() above!
