This patch adds the initial flow framework under Windows OS. It supports
a subset of filters (ETH, IPV4, UDP) and a QUEUE action. It is based on
DevX mechanism to send commands to the NIC through the kernel. It does
not support steering rules (i.e. writing directly to the NIC memory).
The Windows framework uses the existing DV framework where file
mlx5_flow_dv.c remains intact.
Steps involved in flow creation:
1. Create a domain (RX, TX, FDB). Since domains are created by steering
rules and not with DevX, Windows does not require a domain object (this
means switch dev mode which requires an FDB domain is not supported).
2. Create a table object. Windows only supports table 0. The call to
mlx5_flow_os_create_flow_tbl() silently returns successfully.
3. Create a matcher object. A matcher struct is created by calling
mlx5_flow_os_create_flow_matcher(). The matcher validation and
translation are part of the DV implementation. The matcher bits that
were created by DV in standard PRM format are copied into the matcher
struct.
4. Create an action object. The call to
mlx5_flow_os_create_flow_action_dest_devx_tir() creates an action struct
with the TIR type and id. This struct will be a parameter later in a
call to flow creation. All other action calls (e.g. packet reformat,
header modification, jump to flow table, etc) return with a non
supported error.
5. Create the flow. The call to mlx5_flow_os_create_flow() receives the
matcher struct, action struct, and copy them into Windows specific
fs_rule struct, then it calls glue API devx_fs_rule_add().
Details on additional APIs:
* mlx5_flow_os_get_type() is called during flow type selection. In
Windows it constantly returns MLX5_FLOW_TYPE_DV.
* mlx5_flow_os_item_supported() is called before starting DV items
validation or translation. It filters out the OS non supported items in
advance.
* mlx5_flow_os_action_supported() is called before starting DV actions
validation or translation. It filters out the OS non supported actions
in advance.
* mlx5_flow_adjust_priority() is an OS stub for flow priority
adjustment. Windows only supports flow priority 0.

Support VF BDF scanning by checking both the BDF and raw BDF provided by
DevX. In Linux a PCI address is formatted as: domain, bus, device,
function (DBDF). This is right for both a PF and a VF. In Windows a PF
also has a DBDF format, but the domain is always 0, while a VF has a
special "domain" called "Virtual PCI Bus, Serial" (for example: "Virtual
PCI Bus Slot 2 Serial 2") or segment. The full VF format under Windows
is called raw DBF. Windows special domain must be considered and DevX
must be called to support it.

This commit implements mlx5_dev_spawn() API which allocates an eth
device (struct rte_eth_dev) for each PCI device. When working with
representors virtual functions (as in Linux), one PCI device may spawn
several eth devices: the master device for the main physical function
(PF) and several representors for the virtual functions (VFs). However,
currently Windows does not work in switch dev mode, therefore, no VFs
are created and no representors are spawned. In this case one eth device
is created per one PCI main port. In addition to device creation - the
device configuration must be correctly set. The device arguments
(devargs - set by the user) are parsed but they may be overridden by
Windows limitations or hardware configurations. Some associated network
parameters are stored in eth device (e.g. ifindex, MAC address, MTU) and
some callback (e.g. burst functions) are set.

This commit implements mlx5_os_pci_probe API under Windows. It does all
required initializations then it gets the PCI device list using glue API
get_device_list(). Next, all non MLX5 matched devices are filtered out.
The supported NIC types are: CONNECTX4VF, CONNECTX4LXVF, CONNECTX5VF,
CONNECTX5EXVF, CONNECTX5BFVF, CONNECTX6VF, MELLANOX_CONNECTX6DXVF. Each
device in the list is assigned with default configuration parameters,
most of them are 0. The default dv_flow_en parameter value is 1 (which
means Windows match and action flows are based on DV code). Next for
each PCI device call mlx5_dev_spawn() to create an eth device (struct
rte_ethdev). The implementation of device spawn is in the follow up
commit. Finally, the device list is free.
