Having an array of library names and iterating over it looks nicer than having several variables and calling `dlopen()` multiple times manually.
It should also make it easier to use custom library names instead by using the preprocessor, which I plan to do in the near future.
When using icat with tmux we get the following:
```
$ kitty icat ~/Pictures/fc.jpg
Terminal does not support reporting screen sizes via the TIOCGWINSZ ioctl
```
I found a suggestion[1] this is due to limitations between kitty and tmux, so I'm raising this PR to either confirm this is the case and make it clear in the documentation, or to have it rejected so an issue can be raised to address the feature.

GraphicsManager.image_count is declared as a size_t, so the Python type
needs to be the same width. On 64-bit big-endian architectures, this
mismatch was showing up as test failures:

With large objects, use of -fpic will fail to link on certain
architectures due to size limitations of the global offset table (GOT).
For example, the link stage for glfw-wayland.so fails on sparc64, as
below. Using -fPIC avoids these size limitations.

The new types GraphicsCommand can generate a command with only a payload
and no control keys, as the last command during chunked transfer.
Fix the parser to handle this. Fixes#2568
The termcap aliases are not standard, but they are used by Vim, it
seems. As far as I can tell, there are no standard termcap attribute for
strikethrough.
