Nick Craig-Wood 5d6d79e7d4 pacer: fix deadlock with --max-connections 
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.
