I need to add symbolication support for the mochitest Gecko Profiler command line
option. These profiles also need to be symbolicated. Unfortunately, there is not
a common place where I could use these files. Talos and Raptor each had their
own copy of the snappy symbolication server.
This commit consolidates these packages into a re-usable mozbase package that can
be used in mochitests, and eventually in other places like xpcshell tests.
I stubbed out a test file, but it doesn't do anything quite yet. This commit makes
it so that the tests still work in Raptor and Talos, but doesn't add any features.
It also doesn't try too hard to make the files look like a mozbase package.
