Currently the compositor reads cryptomatte meta-data from the render
result. When loading a multilayer open exr file the meta-data was ignored.
This patch will also load the cryptomatte meta-data from multilayer open
exr files.
This enabled workflows where the rendering and compositing are done in
separate scenes or for future changes where the cryptomatte node will
use the meta-data for name matching and color picking.

This patch adds manifest parsing to Cryptomatte. Normally when loading
cryptomatte layer from an OpenEXR file the manifest contains data to
convert a hash to its original name of the object/material. In the
future we want to use this to support lookup of cryptomatte
hashes and show it to the user.
Currently this logic isn't available to users (for now), but is required
by D3959 where a new cryptomatte workflow is implemented.
This change will try to add meta data when using a multilayered open
exr file output node in the compositor. It adds the current scene meta
data and converts existing cryptomatte keys so it follows the
naming that is configured in the file output node.
This change supports the basic use-case where the compositor is
used to output cryptomatte layers with a different naming scheme to
support external compositors. In this case the Multilayered OpenEXR
files are used and the meta data is read from the render result.
Meta data is found when render layer node is connected with the
file output node without any other nodes in between. Redirects and empty
node groups are allowed.
The patch has been verified to work with external compositors.

This new node increases the radiance of an image by a scalar value.
Previously, the only way to adjust the the exposure of an image was with
math node or using the scene's color management.

Replace `typedef` with `using` in C++ code.
In the case of `typedef struct SomeName { ... } SomeName;` I removed the
`typedef` altogether, as this is unnecessary in C++. Such cases have been
rewritten to `struct SomeName { ... };`

During revision of {D8952} one of the comments was to make a function that converts the render percentage to a factor. This to avoid code duplication. However the duplicated code was already all over the compositor code. So in order to avoid this code duplication for {D8952} I propose to first cleanup the duplicated code and build patch {D8952} based on this clean up.
The method that converts the render percentage to a factor is put in the CompositorContext. Why? The CompositorContext keeps DNA information like the renderdata. DNA, and thus the CompositorContext, keeps the size of the render resolution in percentage (user oriented). The compositor needs the size of the render resolution as a factor. So the CompositorContext seems like the obvious place to have this conversion method.
Why not in de NodeBase? The method could've been added to the nodebase, but I wanted to keep the nodebase as clean as possible and not put simple "conversion" methods into this base class. Also I didn't really like the call flow: you'd always have to get the renderdata size from the context and then convert.
Putting it in the CompositorContext avoids this extra invoke of a call.
Why not in the Converter? See nodebase. And the Converter seems more like a class for "structural" and complex node tree conversions. Not the simple conversions.

Don't refresh the list of sockets, so that when the .blend file is restored the
links remain valid. Also display such nodes in red to indicate an error, same
as when the node type info is missing.
Remove redundantly nested `#if` and `#ifdef` statements.
One nested `#if 0` block was left untouched, as it's in particle code
that's no longer maintained. Furthermore, that block also has some
explanation as to the differences between the enabled & disabled parts.
One nested `#if 0` construct was completely removed, leaving only the
actually used bit of code. There was no explanation as to the usefulness
of the disabled code, and it hasn't been touched in years.
No functional changes.
