Summary:                    [patch] 64 bit system channel name uniqueness
Description: 
For sip channels, the channel name is set in sip_new by calling
ast_channel_alloc with format string "SIP/%s-%08x", where the the string is
a host address and the number is a pointer to the channel's private data.

The names of the active sip channels are guaranteed to be unique, only if
asterisk data pointers are 32 bits, that is, when asterisk is compiled on a
32 bit system.

If, on the other hand, asterisk is compiled on a 64 bit system, pointers
are 64 bits and a 32 bit data pointer is ambiguous because heap is
allocated both above and below 4 gigabytes.
