This patch adds the class ExceptionHandlerProtocol to contain all the
relevant types, but should not make any functional changes.

//! \param[in] process_annotations A map of annotations to insert as
//! process-level annotations into each crash report that is written. Do
//! not confuse this with module-level annotations, which are under the
//! control of the crashing process, and are used to implement Chromes
//! “crash keys.” Process-level annotations are those that are beyond the
//! control of the crashing process, which must reliably be set even if

//! To interoperate with Breakpad servers, the recommended practice is to
//! specify values for the `"prod"` and `"ver"` keys as process
//! annotations.
//! \param[in] user_stream_data_sources Data sources to be used to extend
//! crash reports. For each crash report that is written, the data sources
//! are called in turn. These data sources may contribute additional
//! minidump streams. `nullptr` if not required.
