Add two new parameters, ipaConfig and result, to the
IPAInterface::configure() function to allow pipeline handlers to pass
custom data to their IPA, and receive data back. Wire this through the
code base. The C API interface will be addressed separately, likely
through automation of the C <-> C++ translation.

With the internal headers now in include/libcamera/internal/, we may
have identically named headers in include/libcamera/. Their header
guards would clash. Rename the header guards of internal headers to
prevent any issue.

The IPA headers are installed into $prefix/include/libcamera/ipa/, but
are located in the source tree in include/ipa/. This requires files
within libcamera to include them with
#include <ipa/foo.h>
while a third party IPA would need to use
#include <libcamera/ipa/foo.h>
Not only is this inconsistent, it can create issues later if IPA headers
need to include each other, as the first form of include directive
wouldn't be valid once the headers are installed.
Fix the problem by moving the IPA headers to include/libcamera/ipa/.

The libcamera internal headers are located in src/libcamera/include/.
The directory is added to the compiler headers search path with a meson
include_directories() directive, and internal headers are included with
(e.g. for the internal semaphore.h header)
#include "semaphore.h"
All was well, until libcxx decided to implement the C++20
synchronization library. The __threading_support header gained a
#include <semaphore.h>
to include the pthread's semaphore support. As include_directories()
adds src/libcamera/include/ to the compiler search path with -I, the
internal semaphore.h is included instead of the pthread version.
Needless to say, the compiler isn't happy.
Three options have been considered to fix this issue:
- Use -iquote instead of -I. The -iquote option instructs gcc to only
consider the header search path for headers included with the ""
version. Meson unfortunately doesn't support this option.
- Rename the internal semaphore.h header. This was deemed to be the
beginning of a long whack-a-mole game, where namespace clashes with
system libraries would appear over time (possibly dependent on
particular system configurations) and would need to be constantly
fixed.
- Move the internal headers to another directory to create a unique
namespace through path components. This causes lots of churn in all
the existing source files through the all project.
The first option would be best, but isn't available to us due to missing
support in meson. Even if -iquote support was added, we would need to
fix the problem before a new version of meson containing the required
support would be released.
The third option is thus the only practical solution available. Bite the
bullet, and do it, moving headers to include/libcamera/internal/.
