srt-1.3.4-bp151.3.3.1

- Update to version 1.3.4:
  Backported commit 47e5890 and 64875fa to fix CVE-2019-15784 (boo#1148844)
  and avoid a potential array overflow.
  * Added CVE-2019-15784.patch
  * Dropped srt-no-rpath.patch: Fixed upstream.
  * New binary: srt-tunnel
  NOTE: srt-multiplexer binary is now a testing application and
    thus is dropped from our package.
    Upstream found out that does not work as expected issue#422,
    issue#718 and issue#727.

- Fix install prefix in cmake so the pkgconfig file has correct
  information on where to find srt's libraries and include files.

- Add pkgconfig(zlib) BuildRequires: until openssl 1.1.1, zlib was
  pulled in into our buildroot, avoiding srt having to care for it
  explicitly. Since this is changed now, we have to worry for our
  dependency on our own. The dep comes from:
  CMakeLists.txt:set (SSL_REQUIRED_MODULES "openssl libcrypto zlib")

- Trim marketing from description.

- Update to version 1.3.1:
  + Various bugfixes.

- Update summaries.

- Add baselibs.conf: build 32bit support libs.

- Update Summary and Descriptions fields.
