In order to rewrite the Gecko Profiler add-on as a WebExtension,
we need an API for the profiler which allows us to control the
nsIProfiler, and symbolicate the stacks that it provides. This
is the implementation of the simpler parts of that API.
TODO:
- Support profiling of remote targets through a new devtools
API.
- Support the dump_syms breakpad code which was asm.js in the
old extension by directly calling into native code.
- Figure out a faster way to send the large volume of data from
getSymbols all the way from our extension down to the content
process and then into the page's context.
