Since libcamera commit f513fd70ba1a ("subprojects: Drop leftovers of
pybind11"), merged before libcamera v0.1.0, libcamera has no longer
relied on an external subproject branch of pybind to build the python
bindings.
Provide a new package option to allow enabling the python bindings on
libcamera when python3 is available in the buildroot configuration.
Enabling the python bindings will select and bring in pybind as a
dependency.

With upstram commit [1] (since version v0.1.0) the pipeline option 'raspberrypi'
was renamed to 'rpi/vc4'.
Change the buildroot option name from BR2_PACKAGE_LIBCAMERA_PIPELINE_RASPBERRYPI
to BR2_PACKAGE_LIBCAMERA_PIPELINE_RPI_VC4 (and add Config.in.legacy entry
accordingly) and move handling in Config.in/libcamer.mk to follow alphabetic
ordering.

The cam application requires libevent. Since there's no Kconfig option
for it, cam building ability is checked by meson build system by default.
If libevent is present in the sysroot, cam is built.
The issue is that there's no explicit dependency on libevent in
libcamera package. This means that it is possible for libevent AND
libcamera to be built, but have libcamera be built before libevent.
Meaning that even if all requirements seem to be fulfilled, cam still
won't be enabled in some cases.
This fixes the possible race by expliciting the dependency to libevent
if the libevent package is enabled. Otherwise, explicitly disable cam
building as it's already known that it isn't going to build.

Open-Source IPA shlibs need to be signed in order to be runnable within
the same process, otherwise they are deemed Closed-Source and run in
another process and communicate over IPC.
The shlib installed on the target should be the same as the one signed
by libcamera during package creation otherwise the signature won't match
the shlib.
Buildroot sanitizes RPATH in a post build process. meson gets rid of
rpath while installing so we don't need to do it manually.
Buildroot may strip symbols, so we need to do the same before signing.
Signing the IPA shlibs is done by the meson install target, so we need
to strip the IPA shlibs, so after the build but before the install,
which a post-build hooks fits the best.

Cameras are complex devices that need heavy hardware image processing
operations. Control of the processing is based on advanced algorithms
that must run on a programmable processor. This has traditionally been
implemented in a dedicated MCU in the camera, but in embedded devices
algorithms have been moved to the main CPU to save cost. Blurring the
boundary between camera devices and Linux often left the user with no
other option than a vendor-specific closed-source solution.
To address this problem the Linux media community has very recently
started collaboration with the industry to develop a camera stack that
will be open-source-friendly while still protecting vendor core IP.
libcamera was born out of that collaboration and will offer modern
camera support to Linux-based systems, including traditional Linux
distributions, ChromeOS and Android.
The project has not made an official release as of yet, so we're
using the latest sha1 from master
We utilise C++ 11 but we mandate GCC5+ due to a bug [0] in earlier
versions which result in compile failures on our code base.
