Title: Fix inline behavior/warnings under GCC 4.7

When compiling under GCC 4.7 with -Wall, I get
curve25519-donna-c64.c:148:1: warning: always_inline function
might not be inlinable [-Wattributes]
(and so on for every always_inline function.)

A little research suggests that the always_inline attribute isn't
enough on its own: GCC also wants you to use the inline keyword.
Adding the inline keyword makes these warnings go away.
