We used the "browser_initated_post_data" name before because it could only be
initiated from the browser process.  Maybe we should just change it to
post_data.

(I'd also like to look over the CL that introduced it again, since I seem to
remember it being dangerous if renderers could ever set it.  I'll have to see if
we've resolved those concerns.)
