rc: implement operations/discard to read and discard a file

If the pacer was used recursively and --max-connections was in use
then it could deadlock if all the connections were in use at the time
of recursive call (likely).

This affected the azureblob backend because when it receives an
InvalidBlockOrBlob error it attempts to clear the condition before
retrying. This in turn involves recursively calling the pacer.

This fixes the problem by skipping the --max-connections check if the
pacer is called recursively.

The recursive detection is done by stack inspection which isn't ideal,
but the alternative would be to add ctx to all >1,000 pacer calls. The
benchmark reveals stack inspection takes about 55nS per stack level so
it is relatively cheap.

-This can lead to race conditions when performing concurrent transfers. It is up to the user to anticipate these.
-* If two files from the source are transformed into the same name at the destination, the final state may be non-deterministic.
-* Running rclone check after a sync using such transformations may erroneously report missing or differing files due to overwritten results.
