Remove libsrt dependency and integrate compilation into build process

[aaron-jencks]

Uses golang c bindings to integrate the srt library directly into the srtgo library so that libsrt is no longer required.

I see a lot of C++, is there somewhere in particular I should look to see where you integrate it into build process?

you have to look in the .go files, you can see the #cgo lines are modified/added and the import paths are modified

most of the C++ and header files are just copied directly from the srt repo

My machine is missing srt.h so I cannot build. Should there be something in the readme about where/how to get set up for development/building?

[aaron-jencks]

you shouldn't need anything in order to build this, except libssl and libcrypto

I'm having trouble seeing the advantage of this. The last commit states a libssl-dev and libcrypto-dev dependency. Why not add an srt dependency and eliminate the need for all of this? We did this initially in circleci and on the syncbox and catcher.

One of the motivations for switching from UDT to SRT was UDT was no longer maintained and building it was a PITA. How will updates to srtgo be managed? Won't this just become another PITA too?

[gkeiser]

This does seem like it sets us up for an extremely difficult upgrade path.

I discussed with Sam and he still sees the worth of doing this, as opposed to having everybody install/build libsrt
