@File htbserver.c
@Title Host Trace Buffer server implementation.
@Copyright Copyright (c) Imagination Technologies Ltd. All Rights Reserved
@Description Host Trace Buffer provides a mechanism to log Host events to a
buffer in a similar way to the Firmware Trace mechanism.
Host Trace Buffer logs data using a Transport Layer buffer.
The Transport Layer and pvrtld tool provides the mechanism to
retrieve the trace data.
