Building SSSD on GCC 4.7 produces a new warning:
"../src/util/murmurhash3.c:47:17: error: always_inline function might
not be inlinable [-Werror=attributes]"
This patch removes always_inline and replaces it with simply
'inline' (which GCC may remove if it deems it appropriate).
Simo, can you confirm that there's no problem with this? I think it
should be safe.
