linux_usbfs: Deal with receiving POLLERR before all transfers have completed
The linux kernel will set its internal device state to USB_STATE_NOTATTACHED
as soon as it detects the disconnect, and then start a worker thread to
deal with the actual disconnection, kill outstanding urbs, etc.
The usbfs poll implementation will return POLL_ERR as soon as
ps->dev->state == USB_STATE_NOTATTACHED. The kernel will not wakeup
the poll until it is done with processing the disconnection. But if
we happen to call poll() between the state change and the disconnection
being fully processed, we may not be able to reap all outstanding transfers,
even on kernels with the USBFS_CAP_REAP_AFTER_DISCONNECT capability.
This commit deals with this by trying to reap as many transfers as possible
on disconnect on USBFS_CAP_REAP_AFTER_DISCONNECT capable kernels and then
calling usbi_handle_disconnect(handle) to deal with any remaining ones.
On USBFS_CAP_REAP_AFTER_DISCONNECT capable kernels this will be a no-op

core: Refactor code related to transfer flags and timeout handling
Commit
a886bb02 sped up the library a bit by removing the serialization
of transfer submission with respect to the flying_transfers list, but
it introduced two separate issues.
1) A deadlock scenario is possible given the following sequence:
- Thread A submits transfer with very short timeout (say 1ms)
-> takes transfer->lock
-> adds transfer to flying_transfers list and arms timerfd
-> actually calls backend to submit transfer, but it fails
<context switch>
- Thread B is doing event handling and sees the timerfd trigger
-> takes ctx->flying_transfers_lock
-> finds the transfer above on the list
-> calls libusb_cancel_transfer() for this transfer
--> takes transfer->lock
<context switch>
- Thread A sees the transfer failed to submit
-> removes transfer from flying_transfers list
--> takes ctx->flying_transfers_lock (still holding transfer->lock)
** DEADLOCK **
2) The transfer state flags (e.g. submitting, in-flight) were protected
by transfer->flags_lock, but the timeout-related flags were OR'ed in
during timeout handling operations outside of the lock. This leads to
the possibility that transfer state might get overwritten.
This change corrects these issues and simplifies the transfer submission
code a bit by separating the state and timeout flags into their own flag
variables. The state flags are protected by the transfer lock. The timeout
flags are protected by the flying_transfers_lock.
The transfer submission code sheds some weight because it no longer needs
to worry about the timing of events that modify the transfer state flags.
These flags are always viewed and modified under the protection of the
transfer lock. Since libusb_submit_transfer() holds the transfer lock for
the entire duration of the operation, the other code paths that would
possibly touch the transfer (e.g. usbi_handle_disconnect() and
usbi_handle_transfer_completion()) have to wait for transfer submission
to fully complete. This eliminates any possible race conditions.

There is a race between handle_timeout() the completion functions.
When one thread is in handle_timeout() and another thread wakes
up from a poll(), there exists a window where the transfer has been
cancelled, but its USBI_TRANSFER_TIMED_OUT flag is not set yet.
Therefore, usbi_handle_transfer_completion() is sometimes called
with LIBUSB_TRANSFER_CANCELLED instead of the expected
LIBUSB_TRANSFER_TIMED_OUT.
This change adds transfer and flag locks to the handle_timeout()
function.

Add support for persistent device memory.
Add a function to allocate memory belonging to a specific device,
so that the operating system can DMA straight into it for zerocopy,
and also avoid some clearing. Also, this allows up-front memory
allocation in the kernel at program startup; memory allocation is
otherwise done per-transfer, which can fail in a system where memory has become
fragmented over time).
This mirrors new functionality going into Linux' USB stack (recently
reviewed and acked upstream); only Linux is supported as a backend
currently.

naming, reposition function declarations, and address a missing request
during the patch review process.

Windows: Fix false assertion failure message during enumeration
Commit
1d54ee1b6687c532eca75925f56eb12e2a34ce42 addressed a device
reference leak but introduced a false warning message that occurs
for devices detected in early enumeration passes (e.g. hubs). The
assertion is meant to warn of a mismatch between parent devices but
fails to account for the fact that some devices that are allocated
early do not have a parent device assigned until the later
enumeration passes.
