+ Fix getifaddrs realloc pointer error</p>
+ <p>
+ When a buffer was exhausted and subsequently reallocated,
+ we could get an unsafe pointer pointing to faulty memory.</p>
+ <p>
+ For this to occur we would need to have a large number of
+ interfaces and a reallocation of memory to a lower
+ addresses.</p>
+ <p>
+ The symptom would be garbage returned from
+ erlang:port_control(Port, 25, [])
+ (prim_inet:getifaddrs(Port) resulting in a badarg) or a
+ segmentation fault.</p>

+ Don't close all file descriptors twice in child_setup</p>
+ <p>
+ The commit c2b4eab25c907f453a394d382c04cd04e6c06b49
+ introduced an error in which child_setup erroneously
+ tried to close all file descriptors twice.</p>
+ <p>
+ Use closefrom() if available when closing all file
+ descriptors.</p>
+ <p>
+ The function closefrom() was only used in the vfork()
+ case before but is now also used in the fork() case if
+ available.</p>

+ <item>
+ <p>
+ During a crashdump all file descriptors are closed to
+ ensure the closing of the epmd port and to reserve a file
+ descriptor for the crashdump file.</p>
+ <p>
+ If a driver (third party library) cannot handle closing
+ of sockets this could result in a segmentation fault in
+ which case a crashdump would not be produced. This is now
+ fixed by only closing inets sockets via an emergency
+ close callback to the driver and thus closing the epmd
+ socket.</p>
