[Bug 1647285] Re: SSL trust not system-wide

Looks like Fedora substantially modified the scripts used by ca-
certificates to extract untrusted and blacklisted certs. We should
probably start by investigating how their package is handling this, what
files they are generating, and if they are being properly handled by p11
-kit-trust.

Bug description:
  When I install a corporate CA trust root with update-ca-certificates,
  it doesn't seem to work everywhere. Various things like Firefox,
  Evolution, Chrome, etc. all fail to trust the newly-installed trusted
  CA.

  This ought to work, and does on other distributions. In p11-kit there
  is a module p11-kit-trust.so which can be used as a drop-in
  replacement for NSS's own libnssckbi.so trust root module, but which
  reads from the system's configured trust setup instead of the hard-
  coded version.

  This allows us to install the corporate CAs just once, and then file a
  bug against any package that *doesn't* then trust them.

  See https://fedoraproject.org/wiki/Features/SharedSystemCertificates
  for some of the historical details from when this feature was first
  implemented, but this is all now supported upstream and not at all
  distribution-specific. There shouldn't be any significant work
  required; it's mostly just a case of configuring and building it to
  make use of this functionality. (With 'alternatives' to let you
  substitute p11-kit-trust.so for the original NSS libnssckbi.so, etc.)
