This introduces a new argument "--amend" and a new special type of
commit "Amendment". It will check the style of changes that are in
the index combined with the changes of the last commit. So this is
the changes that would be applied by "git commit --amend" hence the
name of the argument.
This is needed to implement pre-commit hook.

This introduces a new command line "--staged" and a new special type of
commit "StagedChanges". It will check the style of changes that are in
the index, so the changes that would be committed by "git commit".
"--staged" was chosen to match with "git diff --staged" command line.
Other valid name could have been "--index" or "--cached". This was
my personal preference, aliases can be added later. Note that we must
not confuse this with working tree changes, as these changes are not
picked by "git commit".
This feature is needed to implement pre-commit hook.

When inserting an element with emplace(), the element is constructed
in-place with the parameters to the emplace() method being forwarded to
the constructor of the element. For std::map containers, the element is
an std::pair<const Key, T>. The constructors of std::pair<T1, T2> fall
into three categories:
(1) Default, copy and move constructors (and related versions)
(2) Constructors that take lvalue or rvalue references to T1 and T2
(3) A forwarding constructor that forwards parameters to the
constructors of T1 and T2
The first category isn't useful in most cases for std::map::emplace(),
as the caller usually doesn't have an existing std::pair<const Key, T>
for the element to be inserted.
The constructor from the third category is useful to avoid constructing
intermediate Key or T instances when the caller doesn't have them
available. This constructor takes two std::tuple arguments that contain
the arguments for the Key and T constructors, respectively. Due to
template deduction rules, usage of such a constructor couldn't be
deduced by the compiler automatically in all cases, so the constructor
takes a first argument of type std::piecewise_construct_t that lets the
caller force the usage ot the forwarding constructor (also known for
this reason as the piecewise constructor). The caller uses a construct
such as
map.emplace(std::piecewise_construct,
std::forward_as_tuple(args_for_Key, ...),
std::forward_as_tuple(args_for_T, ...));
This syntax is a bit heavy, but is required to construct Key and T
in-place from arguments to their non-default constructor (it is also the
only std::pair non-default constructor that can be used for non-copyable
non-movable types).
When the caller of std::map::emplace() already has references to a Key
and a T, they can be passed to the std::pair piecewise constructor, and
this will create std::tuple instance to wrap the Key and T references
arguments to ultimately pass them to the Key and T copy constructors.
map.emplace(std::piecewise_construct,
std::forward_as_tuple(Key_value),
std::forward_as_tuple(T_value));
While this mechanism works, it's unnecessary complex. A constructor of
std::pair that takes references to Key and T can be used without any
performance penalty, as it will also call the copy constructor of Key
and T. In this case we can use a simpler constructor of std::pair, and
thus a simpler call of std::map::emplace.
map.emplace(Key_value, T_value);
We have a couple occurrences of this above misuse of piecewise
construction. Simplify them, which simplifies the code and reduces the
generated code size.

C++14 is a minor release that doesn't introduce major new concepts or
paradigms compared to C++11, but brings two useful changes for us:
- std::make_unique allows dropping our custom implementation in utils.
- Functions returning constexpr are not assumed to be const anymore,
which is needed to create a standard-conformant span implementation.
All the g++ and clang++ versions we support and test (g++-5 onwards and
clang++6 onwards) support C++14. However, due to a defect in the
original C++14 specification, solved in N4387 ([1]), compilation would
fail on g++-5 due to the use of std::map::emplace() with a non-copyable
value type. It turns out we can easily fix it by switching to the
explicit piecewise emplace() overload.
There is thus really nothing holding back the switch. Let's do it, and
update the coding style accordingly.

buffers
The FrameBuffer interface is based on the idea that all buffers are
allocated externally to libcamera and are only used by it. This is meant
to create a simpler API centered around usage of buffers, regardless of
where they come from.
Linux however lacks a centralized allocator at the moment, and not all
users of libcamera are expected to use another device that could provide
suitable buffers for the camera. This patch thus adds a helper class to
allocate buffers internally in libcamera, in a way that matches the
needs of the FrameBuffer-based API.

Extend the pipeline handlers to support the FrameBuffer API with three
new methods to handle allocation, importing and freeing of buffers. The
new methods will replace allocateBuffers() and freeBuffers().
The FrameBuffer API will use the methods on a stream level and either
allocate or import buffers for each active stream controlled from the
Camera class and an upcoming FrameBufferAllocator helper. With this new
API the implementation in pipeline handlers can be made simpler as all
streams don't need to be handled in allocateBuffers().

It's common for applications to create and queue a new request in a
previous request completion handler. When the new request gets queued to
the RkISP1 pipeline handler it tries to find a parameters and statistic
buffer to be used with the request. The problem is if the pipeline depth
is already filled there are no internal buffers free to be used by the
new request.
This was solved by allocation one more parameters and statistic buffer
then the pipeline depth, this is waste full. Instead free the resources
of the request that has completed before it is signaled to the
application, this way if the pipeline depth is full it can reuse the
internal resources and the wasteful allocation can be removed.

With the FrameBuffer interface the V4L2 buffer indexes are not visible
outside the V4L2VideoDevice so it's not possible to to test that the
expected indexes are used when using external buffers (allocated
directly from a V4L2 video device) with a Camera. Rewrite the test to
this limitation.
The idea of the test stays the same, test that buffers allocated from a
V4L2 video device (vivid) can be imported and used on a Camera (vimc).
As an added bonus the rewrite makes use of the FrameBuffer interface for
the allocation of buffers at the source (vivid) and imports them to the
Camera which still uses the Buffer interface internally.

Add a new interface in parallel with the existing Buffer implementation
to also support FrameBuffer. The reason it's added in parallel is to aid
in the migration from Buffer to FrameBuffer throughout libcamera. With
this change discrete parts of libcamera can be migrated and tested
independently.
As the new interface is added in parallel there are some oddities in
this change which will be undone in a follow up patch once libcamera
have migrated away from the Buffer interface.
- There is a nasty hack in V4L2VideoDevice::bufferAvailable(). It is
needed to allow both interfaces to exist and function at the same
time. The idea is if buffers are allocated using the FrameBuffer
interface V4L2VideoDevice::cache_ is set and we know to call the
FrameBuffer 'buffer ready' signal, and likewise if it's not to call
the Buffer variant.
- There is some code duplication between the two interfaces as they aim
to solve the same thing in slightly different ways. As all Buffer
related code is soon to be removed no effort to create code sharing
between them have been made.
- Some function and variables which can't be distinguished by their
argument types have been given a frameBuffer prefix instead of a
buffer prefix. They are clearly documented in the code and will be
renamed to the correct buffer prefix when the Buffer interface is
removed.
