eldritch horrors

libcurl may call callbacks during unpause. if libcurl calls these
callbacks often enough they may find that they've exhausted their
allotted buffer space, at which point they will call dataCallback
as provided in enqueueFileTransfer. download() provides callbacks
that have their own state locks and may call unpause on transfers
with *their* state locks they share with curlFileTransfer. it was
possible to cause a deadlock between these two if the curl worker
thread tried to provide some data to a callback with the transfer
state lock held and the user transfer simultaneously unpaused its
associated curl transfer, with its own state lock held. obviously
not a great situation, but avoidable by not holding any lock when
we unpause transfers and execute their callbacks, as is otherwise
the case when a transfer runs normally and is never paused at all
