Headers which must not be exposed as part of the public libcamera API
should include base/private.h.
Any interface which includes the private.h header will only be able to
build if the libcamera_private dependency is used (or the
libcamera_base_private dependency directly).
Build targets which are intended to use the private API's will use the
libcamera_private to handle the automatic definition of the inclusion
guard.

Move the functionality for the following components to the new
base support library:
- BoundMethod
- EventDispatcher
- EventDispatcherPoll
- Log
- Message
- Object
- Signal
- Semaphore
- Thread
- Timer
While it would be preferable to see these split to move one component
per commit, these components are all interdependent upon each other,
which leaves us with one big change performing the move for all of them.

The libcamera-base.so will feature internal support functionality
that is utilised by libcamera, and can be shared in other places.
This new library provides a layer beneath libcamera which provides
common abstractions to internal objects.
A pkg-config file is generated and named libcamera-base.pc which allows
components such as external IPA modules to link directly to this library
if they need. Normal applications will reference this library through
the Requires: statement provided by the libcamera.pc package
configuration, and linkage will be handled automatically through the
pkg-config mechanisms.
No code is moved to this library yet, this patch only introduces the
framework, construction and linkage.

The LogCategory instances are constructed on first use as static
variables in accessor functions, following the Meyers singleton pattern.
As a result, their destruction order is not guaranteed. This can cause
issues as the global Logger object, constructed in a similar fashion, is
accessed from the LogCategory destructor and may be destroyed first.
To fix this, keep the same singleton pattern, but allocate the
LogCategory instances dynamically. As they get registered with the
global Logger instance, we can destroy them in the Logger destructor.
This only avoids destruction order issues between LogCategory and
Logger, and doesn't address yet the fact that LOG() calls from
destructors of global objects may access an already destroyed Logger.

The V4L2 specification defines the sensor test pattern modes
through a menu control, where a numerical index is associated to
a string that describes the test pattern. The index-to-pattern
mapping is driver specific and requires a corresponding representation
in the library.
Add to the static list of CameraSensorProperties a map of indexes to
libcamera::controls::TestPatternModes values to be able to map the
indexes returned by the driver to the corresponding test pattern mode.

A new utils::Duration class is defined to represent a std::chrono::duration type
with double precision nanosecond timebase. Using a double minimises the loss of
precision when converting timebases. This helper class may be used by IPAs to
represent variables such as frame durations and exposure times.
An operator << overload is defined to help with displaying utils::Duration value
in stream objects. Currently, this will display the duration value in
microseconds.

CameraSensorInfo structure is designed to pass in camera sensor related
information from pipeline-handler to IPA. Since the pipeline-handler
and IPA are connected via mojom IPC IPA interface, the interface
itself provides a more suitable placement of CameraSensorInfo,
instead of camera_sensor.h (which is a libcamera internal header
ultimately, at this point).
As CameraSensorInfo is already defined in core.mojom, it is just
a matter of removing [skipHeader] tag to allow code-generation
of CameraSensorInfo.
Finally, update header paths to include CameraSensorInfo definition
from IPA interfaces instead of "libcamera/internal/camera_sensor.h".

Range-based for loops are handy and widely preferred in C++, but are
limited in their ability to replace for loops that require access to a
loop counter. The enumerate() function solves this problem by wrapping
the iterable in an adapter that, when used as a range-expression, will
provide iterators whose value_type is a pair of index and value
reference.
The iterable must support std::begin() and std::end(). This includes all
containers provided by the standard C++ library, as well as C-style
arrays.
A typical usage pattern would use structured binding to store the index
and value in two separate variables:
std::vector<int> values = ...;
for (auto [index, value] : utils::enumerate(values)) {
...
}

The minimum and maximum vblanking can change when a new format is
applied to the sensor subdevice, so be sure to retrieve up-to-date
values.
The V4L2Device acquires the new updateControlInfo() method to perform
this function, and which the CameraSensor calls automatically if its
setFormat method is used to update the sensor.
However, not all pipeline handlers invoke the setFormat method
directly, so the new method must be made publicly available for
pipeline handlers to call if they need to.

The root cause isn't clear, but this change fixes the issue. It may be a
bug in gcc.

The BoundMethodMember instance created in Signal::connect() for
receivers inheriting from the Object class incorrectly sets the return
type to void instead of R. This doesn't cause any functional issue as
the return type is ignored anyway for signals, but should be fixed
nonetheless.

std::reverse_iterator<iterator> is constructed from an instance of
iterator, and automatically subtracts 1 when dereferencing. rbegin() and
rend() should thus be constructed from end() and begin() respectively.

Replace the __FILE__ and __LINE__ values passed to the _log() function
with default parameters, taking their values from the __builtin_FILE()
and __builtin_LINE() functions. This moves handling of the file and line
from the preprocessor to the compiler, which is generally preferred as
it increases type safety.

The _log() functions, as well as the LogMessage constructor, exist in
two versions, one that takes a log category, and one that doesn't. The
latter uses the default log category. This can be simplified by passing
a LogCategory pointer to _log(), which can then be null for the default
category, and moving the retrieval of the default log category from the
LogMessage constructor to the _log() function.

The ProxyState is only used by the IPAProxy, so it should remain inside
that scope. This helps clarify the usage, and improves the
documentation by bringing the (future) ProxyState documentation into the
class.
