* Add debug info to test whether CM_BUF_WAITING or CM_SCACHE_WAITING
are ever set more than once at a time
* Fix the management of lists of cm_cell_t structures when using
DNS to lookup cell information. The previous code would fail to
reuse the same cellID for a cell if DNS was used more than once
for a given cell name. When the ttl expired, a single cm_cell_t
could be inserted into the cm_allCellsp list more than once
producing a loop. In addition, the vlServerp list belonging to
the cell was not freed resulting in improper refCounting of the
servers.
* Add DNS support to cm_IoctlNewCell() which previous only examined
the CellServDB file
* Add cm_FreeServer() function and call it from cm_FreeServerList()
to properly garbage collect cm_server_t objects
* Add numVCs variable to smb.c to track the number of smb_vc_t
objects created and use it to initialize the vcID field which
previously was set to 0 in all objects resulting in FindByID
collisions.
