Subject: Add NORMAL_BOOST macro
X-Git-Tag: v1.8.0~354^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6c5f88a280214d07b188a2e97ed736535f813195;p=libvpx

Add NORMAL_BOOST macro

Normal frame boost factor is set to be 100 as the baseline for
ARF boost. Replace the hard coded number with a macro.
