class Server

Initialize tracing and prepare for writing trace records for events in

the specified `categories` into `buffer` using `fifo` for signaling.

Tracing hasn't started yet, a `Start()` call is still required.

At most one trace can be active at a time. Subsequent `Initialize()`

requests received prior to a `Terminate()` call must be ignored.

Begin tracing.

If tracing has already started the provider must ignore the request.

There is no result. The provider must send a `TRACE_PROVIDER_STARTED`

packet on `fifo` to indicate success/failure of starting.

Stop tracing.

If tracing has already stopped the provider must ignore the request.

Once the provider has finished writing any final events to the trace

buffer, it must send a `TRACE_PROVIDER_STOPPED` packet on `fifo`.

Note that multiple `Start,Stop` requests can be received between

`Initialize,Terminate`.

Terminate tracing.

Tracing is stopped first if not already stopped.

After tracing has fully terminated the provider must close both

`buffer` and `fifo` to indicate to the trace manager that tracing is

finished.

Gets the trace categories that might be produced by this provider.

|bind_handler| returns a handler that binds incoming connections to this

server implementation.

The returned handler borrows the server instance.

The server must outlive the provided |dispatcher|. Only after

the dispatcher is shutdown will it be safe to destroy the servers.

The server should not be moved.
