Most of the changes in this CL are straightforward. I annotated two changes.

https://codereview.chromium.org/70673004/diff/140001/nss/lib/certhigh/ocsp.c
File nss/lib/certhigh/ocsp.c (right):

https://codereview.chromium.org/70673004/diff/140001/nss/lib/certhigh/ocsp.c#...
nss/lib/certhigh/ocsp.c:3810: CERTSignedData signedData;

The changes in this file come from the upstream changeset
https://hg.mozilla.org/projects/nss/rev/57582eec5eeb

https://codereview.chromium.org/70673004/diff/140001/nss/lib/util/utilmod.c
File nss/lib/util/utilmod.c (right):

https://codereview.chromium.org/70673004/diff/140001/nss/lib/util/utilmod.c#n...
nss/lib/util/utilmod.c:361: PORT_ZFree(moduleList, useCount*sizeof(char **));

This is upstream changeset https://hg.mozilla.org/projects/nss/rev/b782ffd7f0fa

The sizeof in this line should be sizeof(char *) instead of sizeof(char **).
Since the two pointer types have the same size, I didn't bother fixing it
locally.
