Changeset 71492 in vbox for trunk/src/VBox/Runtime/include

Message:

Runtime: Introduce RTTraceLog* API for creating and parsing binary trace log files. The format and API is designed with the

following goals in mind:

1. Allow streaming the data via network or write it to a file.
2. Embed the structure of the traced data into the log allowing arbitrary structured data to be embedded without requiring adaptions on the parsing side.
3. Allow grouping of traced data belonging together to easily follow chains of events later on.
4. Trace events can have a parent assigned to check where an event originally originated from.
5. Low overhead on the creation side.

The current state implements the absolute basics on the creation and parsing side and is work in progress. This will
be used later on in the device emulation fuzzer to capture device and examine device states and changes.
