Removed unused macros/functions that are apparently imported from
LibTomCrypt, only LOAD32L and STORE32L are needed. Remove code that
tries to distinguish between little/big endian, since WORDS_BIGENDIAN
was never defined, this would never have worked on big endian anyway.
Remove the special ROR "optimization" for GCC on i386, modern compilers
are able to optimize it to exactly the same thing. The generic
LOAD32L/STORE32L macros are less optimized (as can be seen in the
generated code), but this was not noticable in the mean running time.
Tested with the packet capture from bug 3232, the result is the same:
tshark -ocorosync_totemnet.private_keys:example.com -r corosync-totemsrp--key:example.com--2nodes.pcap -Vx
