Mk/Uses/samba.mk: Introduce 3 new SAMBA_*_PORT variables

* Introduce 3 new variable, SAMBA_TALLOC_PORT, SAMBA_TDB_PORT and
  SAMBA_TEVENT_PORT. Proper port origin ("databases/ldb29" for
  example) is assigned to them depending on the value of
  SAMBA_DEFAULT. They are intended to be used by ports that works with
  Samba to specify proper version of talloc, tdb and/or tevent as
  dependency.
* Add item in CHANGES.

+  3 new variables are defined if you add 'USES=samba' in Makefile.
+
+  * SAMBA_TALLOC_PORT
+  * SAMBA_TDB_PORT
+  * SAMBA_TEVENT_PORT
+
+  They are intended to be used by ports that works with Samba to
+  specify proper version of talloc, tdb and/or tevent as dependency
+  such as bellow.
+
+      LIB_DEPENDS=	ibtalloc.so:${SAMBA_TALLOC_PORT} \
+			libtdb.so:${SAMBA_TDB_PORT} \
+			libtevent.so:${SAMBA_TEVENT_PORT}
+      USES=		samba:env
+
+  You need not use them if port just depends on talloc, tdb and/or
+  tevent and it has nothing to do with Samba.
