9143668887 libcamera: ipc_unixsocket: Use UniqueFD for a file descriptor
IPCUnixSocket::create() creates two file descriptors. One of
them is stored in IPCUnixSocket and the other is returned to a
caller. This clarifies the ownership using UniqueFD.

59002a9e9d test: Replace "/proc/self/exe" with path to test binary
When tests are run under valgrind, /proc/self/exe points to valgrind,
not to the test binary. This results in failures for tests that need to
fork processes. Fix it by replacing "/proc/self/exe" with the path to
the test binary.

b24d9c4413 test: Store path to the test executable in Test class
Store the path to the test executable, found in argv[0], in the Test
instance. This can be useful for tests that need to fork processes.

3335d5a504 libcamera: Drop emitter object pointer from signal arguments
Many signals used in internal and public APIs carry the emitter pointer
as a signal argument. This was done to allow slots connected to multiple
signal instances to differentiate between emitters. While starting from
a good intention of facilitating the implementation of slots, it turned
out to be a bad API design as the signal isn't meant to know what it
will be connected to, and thus shouldn't carry parameters that are
solely meant to support a use case specific to the connected slot.

These pointers turn out to be unused in all slots but one. In the only
case where it is needed, it can be obtained by wrapping the slot in a
lambda function when connecting the signal. Do so, and drop the emitter
pointer from all signals.

3f662ae3c0 libcamera: Don't use emitter object pointer argument to slot
In many cases, the emitter object passed as a pointer from signals to
slots is also available as a class member. Use the class member when
this occurs, to prepare for removal of the emitter object pointer from
signals.

In test/event.cpp, this additionally requires moving the EventNotifier
to a class member.

27aff949fb libcamera/base: Move extended base functionality
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.
