This patch reduces the stack usage by declaring 'const' stack variables

as 'static const' so they end up in the .rodata section instead of being
copied from there to the stack for every invocation of the corresponding
function. As a plus we end up in having a smaller binary as the "copy
from .rodata to stack" code isn't emitted by the compiler any more
(roughly -100 bytes).
