.CooCoo 69c268014e craft-print: serialize calls to the Windows PrintTicket provider (#171) ...

The first time a process opens a PrintTicket provider for a queue whose
provider is PrintConfig.dll, winspool.drv creates a process-wide cache
without a lock. When two threads make those first calls together,
winspool can keep a pointer to a cache it has already freed, and a later
PTOpenProvider call crashes the process with an access violation in
ntdll. Listing printers from several threads at once reaches it through
two_sided.

Hold one process-wide lock around every call that reaches the provider:
PrintCapabilities::fetch in two_sided and driver_ticket, the
PrintTicketBuilder in driver_ticket, fetch_xml_for_ticket in
imageable_margin, and the start of print_with_progress, where winprint
converts the ticket to a DEVMODE. The job releases the lock at its first
progress report, before it sends progress to the submitting thread. A
lock poisoned by a panic is still taken.
