Fix #197: Missing braces in for loop

[Zenexer]

Fixes #197.

[fduncanh]

Those braces are optional, it's a one line "for" statement. Your proposed change is cosmetic.

[Zenexer]

@fduncanh They aren't optional if that entire line is meant to be looped. Currently, it's effectively this:

for ( i = 0; i < s->payloadSize; i++ ) {
    printf("%ld.%d: ", (long int)(b->p - b->start), b->bits_left);
}

s->data[i] = bs_read_u8(b); printf("s->data[i]: %d \n", s->data[i]); 

Implicit braces are per-statement, not per-line.

[fduncanh]

sorry, you are right of course.
Luckily, from the function name it seems to be in code only used
at some time for debugging h264-bitstream code.

It's never referenced unless HAVE_SEI is defined, which appears not to be the case. (so it appears to
be dead code)

In my use (not RPi) of RPiPlay, that h264-bitstream code is never compiled,

[fduncanh]

you should report it upstream here: (there appears still to be someone occasionally looking at issues there)

Yeah, please report it to upstream! We're not using that part of the code, but other consumers of h264bitstream may.
