etc/dlist: add simple userspace doubly-linked list abstraction
Add a very simple implementation for managing a doubly-linked list.
This implementation uses only a 'list entry' structure for both the
list and items on the list, versus separate structures like complib.

[NetworkDirect] Enable Network Direct IB provider builds.
if HPC SDK installed (ND_INC defined) then build for x86 & x64 - no IA64 ND support until ND over Winverbs.
if !HPC SDK installed, skip ND provider build for all architectures.
[ND] reverting back to fake ND sources file so build out-of-svn works again.
Once MS supplied sources file actually builds something useful, will reinstate their sources file.
[HW] Pass IRP_MN_QUERY_INTERFACE IRP down the stack.
This patch changes the HCA driver to pass any IRP_MN_QUERY_INTERFACE IRP down the stack if the interface is supported, after setting the IRP status to STATUS_SUCCESS. The bottom-most driver will complete the IRP without changing the status.

This patch fixes issues with connection establishment for NetworkDirect. The root cause of the issue is 'too many cooks' - CIDs exposed to user-mode should not be destroyed in the kernel code without explicit request from the user. Otherwise, the CID can get recycled in the kernel for the same process and improperly freed when the stale CID is released by the application (multiple connection objects in the app have the same CID.)
Unfortunately, the fix is not simple. The QP references the CEP, so QP destruction frees the CEP, even if there's a reference to that CEP left in the application. Removing the CEP reference form the QP solves this problem, but deadlocks the app if it destroys the QP before the CEP, since the QP is used to queue connection-related IRPs, and the CEP uses the QP as its context and so holds a reference on it.
This patch does the following:
- Remove CEP reference for ND related QP.
- Remove ND connection related IRP queue from QP.
- Remove ND IRP handling from CEP manager.
- Add a function to CEP manager to reference the context associated with a CEP if the context is non-NULL.
- Move ND connection related IRP management into al_ndi_cm.c, in nd_csq_t structure.
As part of testing, I needed to add NotifyDisconnect functionality, so this is also included in the patch.
Note that the patch depends on Sean's previous patch to change kal_cep_destroy to allow silently dropping a REQ. I did not remove Sean's previous changes from this patch, so they are duplicated here. This allows the patch to be applied and build.

[MLX4_BUS] Bad order of operations in mlx4_ib teardown process. [mlnx: 4208]
The bug is that the driver performs "CLOSE_PORT" command prior to closing all resources (such as QPs).
In some cases it causes loss of completions.
According to PRM:
18.2 ConnectX Driver Teardown and Re-initialization
The HCA can be shut down (and re-initialized/restarted later on) by software. This operation is performed while the system shuts down gracefully or when PCI bus re-enumeration and memory re-allocation is required. In this case, software should perform the following steps:
•Stop HCA operations (tear-down all QPs and flush WQEs if required).
•Take down the network links by executing the CLOSE_PORT command.

[CORE,HW] remove PDO from the upper HCA interface. [mlnx: 4197]
This patch removes p_hca_dev field of the upper CA interface (ci_interface_t), which contains PDO of HCA device.
IBBUS, now sitting over HCA, gets this PDO in add_device function and stores it (in this patch) in new p_hca_dev field in IBAL CA object.
All the usages of ci_interface_t.p_hca_dev field is replaced by usage of p_hca_dev in IBAL CA object.
p_hca_obj field, added in 2019 patch in RDMA_INTERFACE_VERBS, removed and placed instead of p_hca_dev in ci_interface_t.
Removing of PDO filed from the interface required changing of ib_register_ca prototype (for technical reasons).
It is - an interface function, so the interface version number was increased (IB_CI_INTERFACE_VERSION=5).

IBBUS start up was two-phased by design, because HCA, sitting in another stack, could have come later them IBAL.
Now it can't happen. So i added a wait on event at the end of the first phase, which is posted at the end of the second phase - PnP notification on arrival of HCA.

[QLGC VNIC] VNIC configuration tool.
Part of the solution for having a vendor defined device created by ibiou. This tool sends device IOCTLs to IBIOU for listing the reachable IOCs and for creation of child PDOs.

[IBAL] Only create CEPs for REQs that matched to a listen.
Currently, the CM creates a CEP for an incoming REQ before matching to either a listen or a Peer-to-Peer connection request. As Peer-to-Peer is not supported, this means that CEPs are created before matching the incoming REQ to a listen. In the case where there is no listen, this will result in CEPs being created, and then queued for destruction to the timewait timer callback. Because the CEPs have a timewait time of zero, the timer callback runs as fast as REQs are received, severely affecting system responsiveness.
This patch moves the CEP creation after matching against listens, avoiding creation altogether if there is no listening endpoint.

[CORE] Expose vendor defined device in ibiou.
IBIOU driver doesn't create child PDO's on discovering a EVIC IOC.
It's behavior for SRP target IOCs is not altered and child devices for SRP targets will get created on their discovery.
IBIOU keeps a global list of reachable IOCs in iou_globals. IBIOU add/delete entries in this list on IOC ADD and IOC REMOVE PnP events.
User mode utility "qlgcvnic_config" is used to list all the reachable IOCs to the user and then to create the VNIC PDOs.
"qlgcvnic_config" uses device IOCTLs to communicate with the IBIOU driver.
IBIOU creates the devices only if sees that EVIC IOC is reachable from the particular CA.
"qlgcvnic_config" utility writes this device information into the registry also, so that IBIOU can pick up these device creation information on
next reboot.
In initialization phase, IBIOU reads the child device information from the registry and makes a list of VNIC child devices to be created.
On each IOC add events, it traverses the child device list (prepared during initialization) and create the child PDO for matching child device entries.

etc/comp_channel: add completion channel abstraction for scalability
Add a new abstraction, the completion channel, capable of de-multiplexing
overlapped completion events among multiple queues.
The completion abstraction consists of 3 main components:
COMP_MANAGER
Maps to an IOCP. The completion manager tracks all completions on any
of its associated channels. This allows a user to 'poll' the completion
manager to receive notification when a completion event occurs on any
of the channels, similar to polling a set of fd's.
COMP_CHANNEL
Maps to a queue of completed requests. A user can 'poll' a single channel
for completions if they are only interest in processing events on that
channel. Internally, polling on a channel will poll the manager for
completions, but only process those associated with the specified channel.
COMP_EVENT
Maps to an overlapped structure. Operations needing a completion event
reference this structure. When the event occurs, it is queued to the
correct channel.
The implementation assumes that only one or a very small number of threads
will ever be trying to process events at any one time. (Based on existing
applications, this is true.) The abstraction itself is threadless.
