replace zero-length arrays with flexible ones

Browse Source 
This patch replaces instances of zero-sized arrays i.e. those at the end
of structures with "[0]" with the more standard syntax of "[]".
Replacement was done using coccinelle script, with some revert and
cleanup of whitespace afterwards.
