Cleanup and reorganize includes With this commit a unified structure for includes is introduced. The general rules: * Only include what you need * Include wherever possible in the cpp and forward-declare in the header The includes are sorted in a local to global fashion. This means for the include order: 0. If cpp file: The corresponding h file and an empty line 1. Includes from the project sorted alphabetically 2. System/library includes sorted alphabetically 3. Conditional includes

Image: Replace qsort with std::sort std::sort has stricter complexity requirements than qsort and can be better optimized by the compiler due to templating.

FIFO support for zoneminder zone debugging (#2594) Adds fifo options for diagnostic images for much lower impact diagnostics mode. Diagnostic images are only written when there is a client listening for them (otherwise they are skipped). Also added a json stream for the detection data so you can see in real time the pixels or blobs detected for the motion. This allows for easy real time stream of both delta and reference images (as video streams) along with the detection numbers.

Eliminate non-thread-safe calls to localtime localtime uses an internal static storage to which a pointer is given as return value. Due to this it is not safe to call localtime from multiple threads since the same static storage is used. Use localtime_r instead which allows to pass in a tm struct.

Eliminate non-thread-safe calls to localtime localtime uses an internal static storage to which a pointer is given as return value. Due to this it is not safe to call localtime from multiple threads since the same static storage is used. Use localtime_r instead which allows to pass in a tm struct.
