Patch changing the way of accessing interrupt handle also changed order
of the rte_pci_map_device() call and rte_pci_device:driver assignment.
It was causing issues with Write Combine mapping on the Linux platform
if it was used with the igb_uio module.
Linux implementation of pci_uio_map_resource_by_index(), which is called
by rte_pci_map_device(), needs access to the device's driver. Otherwise
it won't be able to check the driver's flags and won't respect them.

Currently there are some public headers that include 'sys/queue.h', which
is not POSIX, but usually provided by the Linux/BSD system library.
(Not in POSIX.1, POSIX.1-2001, or POSIX.1-2008. Present on the BSDs.)
The file is missing on Windows. During the Windows build, DPDK uses a
bundled copy, so building a DPDK library works fine. But when OVS or other
applications use DPDK as a library, because some DPDK public headers
include 'sys/queue.h', on Windows, it triggers an error due to no such
file.
One solution is to install the 'lib/eal/windows/include/sys/queue.h' into
Windows environment, such as [1]. However, this means DPDK exports the
functionalities of 'sys/queue.h' into the environment, which might cause
symbols, macros, headers clashing with other applications.
The patch fixes it by removing the "#include <sys/queue.h>" from
DPDK public headers, so programs including DPDK headers don't depend
on the system to provide 'sys/queue.h'. When these public headers use
macros such as TAILQ_xxx, we replace it by the ones with RTE_ prefix.
For Windows, we copy the definitions from <sys/queue.h> to rte_os.h
in Windows EAL. Note that these RTE_ macros are compatible with
<sys/queue.h>, both at the level of API (to use with <sys/queue.h>
macros in C files) and ABI (to avoid breaking it).
Additionally, the TAILQ_FOREACH_SAFE is not part of <sys/queue.h>,
the patch replaces it with RTE_TAILQ_FOREACH_SAFE.

For device probe and iterator, devargs name was key information,
parsed by rte_devargs_parse. In legacy parser, devargs name was
extracted after bus name:
bus:name,kv_arguments,,,
Example:
pci:83:00.0,arguments,...
vdev:pcap0,...
To be compatible with legacy parser, this patch introduces new
bus driver API devargs_parse to parse devargs and update devargs name.
If devargs_parse not implemented by bus driver, the new syntax parser
rte_devargs_layers_parse default will resolve devargs name from bus's
"name" argument.
Different bus driver might choose different keys from arguments with
unified format. The PCI bus implementation fills the devargs name with
the "addr" argument, example:
-a bus=pci,addr=83:00.0/class=eth/driver=mlx5,...
name: 0000:03:00.0
-a bus=vdev,name=pcap0/class=eth/driver=pcap,...

Currently virtio PMD assumes legacy device uses PIO bar.
There are three ways to get PIO (port-mapped I/O) address for virtio

1) under igb_uio
- get PIO address from uio/uio# sysfs attribute, for instance:
/sys/bus/pci/devices/0000:00:09.0/uio/uio0/portio/port0/start
2) under uio_pci_generic
- for X86, get PIO address from /proc/ioport
- for other ARCH, get PIO address from standard PCI sysfs attribute,
for instance: /sys/bus/pci/devices/0000:00:09.0/resource
Actually, "port0/start" in igb_uio and "resource" point to exactly the
