Add a formatter to ensure consistent naming of 'd' and 'o' variables
related to the d-pointer design pattern, as implemented by the
Extensible class. The formatter also ensures that the pointer is always
const. const-correctness issues related to the data pointed to will be
caught by the compiler, and thus don't need to be checked here.

Implement tracing infrastructure in libcamera. It takes .tp files, as
required by lttng, and generates a tracepoint header and C file, as lttng
requires. meson is updated accordingly to get it to compile with the
rest of libcamera. Update the documentation accordingly.

For each Control that supports enumerated values generate an array
of ControlValue which contains the full list of valid values.
At the expense of a slight increase in memory occupation this change
allows the construction of the ControlInfo associated with a Control
from the values list, defaulting the minimum and maximum values
reported by the ControlInfo.

Extend the control and property framework to support exposing draft
controls and properties in a scoped namespace.
The controls/properties themselves will retain the same ordering in the
relevant enum/id maps - but the access to any draft control will require
explicitly referencing through its' draft:: namespace prefix.

While libcamera prefers usage of the C standard library headers (xxx.h)
over the C++ version (cxxx), we make an exception for cmath as the

Having the build time in the version string is useful when building from

Indentation is handled by outputting spaces right after outputting a
newline character. That works in most cases, but would result in the
input '{}' being printed as
{
}
instead of
{
}
Fix it by outputting the indentation before outputting the next
character after a newline. The indentation value will be updated by
then.

In an attempt to clarify the license terms of all files in the libcamera
project, the build system files deserve particular attention. While they
describe how the binaries are created, they are not themselves
transformed into any part of binary distributions of the software, and
thus don't influence the copyright on the binary packages. They are
however subject to copyright, and thus influence the distribution terms
of the source packages.
Most of the meson.build files would not meet the threshold of
originality criteria required for copyright protection. Some of the more
complex meson.build files may be eligible for copyright protection. To
avoid any ambiguity and uncertainty, state our intent to not assert
copyrights on the build system files by putting them in the public
domain with the CC0-1.0 license.
