2020-04-30qcam: Fix logging of sequence numberLaurent Pinchart
The sequence number of captured frames is logged to the console with padding to 6 characters to increase readability. The output is however incorrect, as 123 is printed as 00012300000. This is caused by the auto-space feature of QDebug, which inserts a space after every field. This doesn't play well with stream format manipulation, as it ends up padding the automatically inserted space the same way as the previous argument. This is a bug in Qt, work around it by formatting the sequence number manually.

2020-04-29libcamera: Regenerate IPA module signatures at install timeLaurent Pinchart
When the IPA modules are installed, meson strips the DT_RPATH and DT_RUNPATH from the binaries. This invalidates the signatures. Disable installation of the .sign files and add an installation script to regenerate them directly in the target directory. The .sign files still need to be created at build time to support running IPA modules from the build tree. Two alternative approaches have been considered: - meson could be taught a new target argument to preserve binary compatibility by skipping any operation that modifies files. This has been proposed in the #mesonbuild IRC channel. While this could be interesting in the longer term, we need to fix the issue now. - The module signatures could be computed on selected sections only. While skipping the .dynamic section when signing may not cause security issues, it would make signature generation and verification more complex, and wasn't deemed worth it.
