This update for live555 fixes the following issues:

- CVE-2019-9215: Malformed headers could have lead to invalid memory
  access in the parseAuthorizationHeader function. (boo#1127341)

- CVE-2019-7314: Mishandled termination of an RTSP stream after RTP/RTCP-over-RTSP has been set up could have lead to a Use-After-Free error causing the RTSP server to crash or possibly have unspecified other impact. (boo#1124159)

- Update to version 2019.06.28, 
- Convert to dynamic libraries (boo#1121995):
  + Use make ilinux-with-shared-libraries: build the dynamic libs
    instead of the static one.
  + Use make install instead of a manual file copy script: this
    also reveals that we missed quite a bit of code to be installed
    before.
  + Split out shared library packages according the SLPP.
- Use FAT LTO objects in order to provide proper static library.
