This patch fixes the segfaults I introduced in the previous conneciton caching patch. It cleans up the connection cache a *lot* - in particular it adds significant robustness to the operation. If a the DC goes down, we no longer fail the next operation - the code checks if the connection died during one of its own operations on the socket, and restarts the conneciton as required. There is still a memory leak in here somewhere - but this code also cleans up a number of these. Also added is the abilty to sepecify the domain of the 'get around restrict anonymous' user that winbind uses. Andrew Bartlett (This used to be commit 92cbefdf2783bf9dbbb2179c1b2f7cdb802d84a9)
