2022-06-04py: Merge read_event() and get_ready_requests()Tomi Valkeinen
We always call CameraManager.read_event() and CameraManager.get_ready_requests(), so to simplify the use merge the read_event() into the get_ready_requests(). This has the side effect that get_ready_requests() will now block if there is no event ready. If we ever need to call get_ready_requests() in a polling manner we will need a new function which behaves differently. However, afaics the only sensible way to manage the event loop is to use select/poll on the eventfd and then call get_ready_requests() once, which is the use case what the current merged function supports.

2022-05-27py: Use ln --relative to create symlinksTomi Valkeinen
We create symlinks from the Python bindings build dir to the source dir so that 1) the build dir can be used to use the bindings, and 2) to allow modifications of the source .py files to be used right away without rebuilding. The symlinks were recently fixed and changed to use absolute paths. However, absolute paths ruin one main use case I have: using the bindings from the build dir via nfs from an ARM device. So move back to relative paths, but accomplish this with the --relative parameter for ln, instead of guessing the right relative path as was done before the above-mentioned fix.
