Bug#855879: Please add blapi.h to libnss3-dev

[Timo Aaltonen]

Package: libnss3-dev
Severity: normal

Hi, I need to package nss-pem for certmonger to actually be able to
renew certificates, but it fails to build because blapi.h is missing
from libnss3-dev. Ubuntu has carried it for some time for some reason,
please add it in Debian too.
