When a gpio is exported by writing in /sys/class/gpio/export, the
corresponding gpio control files appear immediately in sysfs but
with default access permission for root user only. The daemon udev
requires some time to get notified of the new files before it can
change the permissions to allow access to unprivileged users.
Due to this race condition, sysfsgpio can fail with EACCES error
if OpenOCD is executed by any unprivileged user.
Give 0.5 seconds to udev to identify the new files and change the
permission.
Tested with udev rules:
SUBSYSTEM=="gpio*", PROGRAM="/bin/sh -c 'find -L /sys/class/gpio/ -maxdepth 2 -exec chown root:uucp {} \; -exec chmod g=u {} \; || true'"

Commit c2e18bfaea changed the size of the JTAG-to-SWD sequence
from 15 bytes to 17 bytes. This broke SWD switch sequence transfer
for buspirate, since buspirate packets can only hold a payload of up
to 16 bytes and we tried to fit the whole sequence in a single packet.
Splitting up the sequence transfer in appropriately sized packets
makes buspirate SWD work again (successfully tested with buspirate
firmwares v6.1 and v7.0).

time between USB transfers such as is seen on some virtual machines.
This change is only supported when compiled with libusb1 as libusb1

Multi-transaction queueing introduced in this change paves the way for
