Use C99 named initializers to fill in events passed to XSendEvent
Forces compiler to zero-fill unset fields in the struct (fixing bug 81236)
and allows optimizer to order field initialization to best fit cache layout

Before & after output of gcc -S on AMD64 shows insertion of "rep stosq"
instructions to rapidly zero-fill structs.
