Logger

The logger WLog is capable of supporting various backends (stdout, files, sockets, ...)
Can be filtered:
- Global log level
- Different logging levels per TAG
Static and dynamic use
- Static for use where the message is not performance critical (A global tree is searched to finding the corresponding logger)
- Dynamic to speed things up (A reference to the logging configuration is held in memory)

Backtracing

With the primitives in winpr/include/winpr/debug.h a stack trace can be obtained (or logged to WLog)
Verbosity of these backtraces depends on compilation settings
Debug symbols are required for human readable traces
