NoBug debugging library 0.2 / 0.3pre1

NoBug debugging library is a simple debugging library (only a single nobug.h header) similar to gnu-nana and Design-by-Contract ideas.
Main features:
- Three different levels for checks (in depth to final no-overhead)
- Scope tags (tell whenever a function or loop is considered to be bug free)
- Pre-, Postcondition and Invariant checks, generic Assertions
- Debugger support (actions are only executed while running under a debugger), currently only valgrind
- Dumping of your datastructures
- Logging your applications activities
- Runtime customizable logging via an enviromnet variable
- Different logging targets (stderr, syslog, debugger...)
- Annotation of your sourcecode about known bugs, things to do and planned things
Whats New in 0.2 Stable Release:
- The source code location handling (file/line/function) was improved and centralized.
- Logging flags in C++ applications can be initialized and parsed with a simple initializer.
- The Resource Registry was stabilized and rewritten and given a new interface.
- Resources can be acquired in three states.
- Multithreading support for the Resource Registry was improved.
- All actions on the Resource Registry can emit logging messages.
- Only a few fixes were made since the 0.2rc1 release.
Whats New in 0.3pre1 Development Release:
- A deadlock detector was added. This is a review release, a work in progress.
