Remove unneeded null check for entry in for loop
In vpx_codec_control_(), before we enter the for loop, we have already
checked if ctx->iface->ctrl_maps is null and handle that as an error. So
the for loop can assume ctx->iface->ctrl_maps is not null, which implies
'entry' is not null (both initially and after entry++).

test/*.sh: add explicit error checks/returns
there was an assumption that function calls would terminate early with
an error given 'set -e' was being used. this is true, but only when the
function is part of a simple command otherwise it won't inherit the
behavior. many of the call sites use 'func || return 1' syntax meaning
the function would continue to completion return with the status of the
last command executed. this hid errors with e.g., eval statements. inner
calls within the functions are now explicitly tested for failure.

Optimize vp9_get_sub_block_energy.
Because energy scaling is non-decreasing, we can work on the variance

Use ObserveGroupOfPicture() in EncodeFrame test
In the previous version, we assume the number of coding frames is
