Previously, StartHandler() launched the handler process, then connected
over a pipe to register for crash handling. Instead, the initial client
can create and inherit handles to the handler and pass those handle
values and other data (addresses, etc.) on the command line.
This should improve startup time as there's no need to synchronize with
the process at startup, and allows avoiding a call to CreateProcess()
directly in StartHandler(), which is important for registration for
crash reporting from DllMain().
Incidentally adds new utility functions for string/number conversion and
string splitting.
Note: API change; UseHandler() is removed for all platforms.

This is a temporary measure to try to account for lower than expected
upload volume from Chrome in the wild. So this doesn't fix bug 23, but
is related. The ability to delimit the upload rate is useful when
testing locally too.

Allowing the client to create its own pipe name string caused a race
between client and server. Instead, in this mode, the server now creates
the pipe name along with a pipe, and returns it to its client via a
--handshake-handle. This guarantees that by the time the client gets the
pipe name, the server has already created it.
Ephemeral mode is now implied by --handshake-handle. The --persistent
option is gone. --persistent mode is enabled when using --pipe-name.

By invoking crashpad_handler with --mach-service instead of
--handshake-fd, the handler will run as a well-behaved launchd job. The
launchd job may be as a launch agent or launch daemon, or be submitted
to launchd by on_demand_service_tool.

This is a weird option that causes crashpad_handler to discard the crash
handler it inherited and replace it with the system default. Its use is
not recommended.
