curl: do not do aio_poll when waiting for a free CURLState
Instead, put the CURLAIOCB on a wait list and yield; curl_clean_state will
wake the corresponding coroutine.
Because of CURL's callback-based structure, we cannot easily convert
everything to CoMutex/CoQueue; keeping the QemuMutex is simpler. However,
CoQueue is a simple wrapper around a linked list, so we can easily
use QSIMPLEQ and open-code a CoQueue, protected by the BDRVCURLState
QemuMutex instead of a CoMutex.
