+ * Names are looked up first if present, then IDs are compared if present. In

+ *    ok  --  --  | proxy deleted, but other half with same name still here (before)
+ *    ok  --  ok  | proxy's ID changed (proxy moved in the config file)
+ *    ok  ok  --  | proxy deleted, but other half with same name still here (after)
+ *    ok  ok  ok  | perfect match
+ *
+ * Upon return if <diff> is not NULL, it is zeroed then filled with up to 3 bits :
+ *   - PR_FBM_MISMATCH_ID        : proxy was found but ID differs
+ *                                 (and ID was not zero)

+ *                                 (and name was not NULL)
