Shared library ABI for custom data sources

This commit implements an ABI and API for the shared library to support
registering custom data sources and creating tracing packets on them.

Most of the features of the C++ data sources are supported. Exceptions
are:
* Using custom thread local storage (not to be confused with custom
  per-instance thread local state, which is supported). The feature in
  C++ relies on heavily inlined template Traits. It is only used by the
  TrackEvent data source implementation, which in the shared library is
  going to has a separate ABI.
