Hello everybody,

Here's the second version of the event notification and timer support
patch series for libcamera.

The series starts with small cleanups and changes (01/11 to 04/11), and
then adds a signal/slot mechanism (05/11) that serves to implement event
nofication in the event notifier and the timer (06/11). Patch 07/11 adds
a default poll()-based implementation of the event dispatcher that is
used by libcamera when the application doesn't provide its own
implementation. Patches 08/11 to 11/11 finally add corresponding test
cases.

I've incorporated (to the best of my knowledge) all the feedback I've
received on v1. Please see individual patches for changelogs.

Laurent Pinchart (11):
  libcamera: log: Add a LogFatal log level
  libcamera: log: Add an ASSERT macro
  libcamera: log: Pad timestamp fields with zeros
  libcamera: camera_manager: Make the class a singleton
  libcamera: Add signal/slot communication mechanism
  libcamera: Add event notification infrastructure
  libcamera: Add a poll-based event dispatcher
  test: Rename list test to list-cameras
  test: Add signal/slot test
  test: Add timer test
  test: Add event notifier test
