[libcamera-devel] [PATCH v4 0/3] MediaDevice class and MediaObject classes

[Jacopo Mondi]

Hello
   this is 4th version of MediaDevice and associated MediaObject classes.

v1 available for reference here:
https://lists.libcamera.org/pipermail/libcamera-devel/2018-December/000120.html
v2 available for reference here:
https://lists.libcamera.org/pipermail/libcamera-devel/2018-December/000181.html
v3 available for reference here:
https://lists.libcamera.org/pipermail/libcamera-devel/2018-December/000239.html

I have addressed here comments on Niklas and Laurent on v3. Most notable changes
are:

- Simplified destructors, and have all object destroyed by the MediaDevice
  iterating over the global pool of objects. MediaPad and MediaEntity
  destructors only clear the list containers and do not delete objects they
  are associated with (thanks Laurent)
- Simplified the populate() function clean up (thanks Niklas)
- Polish and use \return everywhere in comments (thanks Niklas)

Tested locally using the printout test on VIMC and integrated webcam media
devices.

Valgrind does not report memory leaks.

I consider this version ready to be pushed, even if only 1/3 has received
a reviewed-by tag by Laurent.

Thanks
