Enable an io-uring build
There exists a bug where calls that we previously thought were
non-blocking, actually do block when used with hwmon or filesystem fds.
This causes high latencies on the dbus interfaces when lots of sensors
are used in a single daemon, as is the case in PSUSensor.
This patchset moves the PSUSensor code over to using io-uring, through
boost asio, using the random_access_file class. This helps with
performance in a number of ways, the largest of which being that sensor
reads are no longer blocking.
Tested:
Booted the sensor system on Tyan S7106; dbus-monitor shows sensors
scanning normally.
