winverbs: fix race in async connect handling

If an application calls Connect or Accept, their IRP is queued to a
work queue for asynchronous processing.  However, if the application
crashes or exits before the work queue can process the IRP, the cleanup
code will call WvEpFree().  This destroys the IbCmId.

When the work queue finally runs, it can access a freed IbCmId.
This is bad.  A similar race exists with the QP and the asynchronous
disconnect processing.  The disconnect processing can access a
the hVerbsQp handle after it has been destroyed.

Additionally, in all three cases, the IRPs assume that the WV provider
is able to process IRPs.  Specifically, they require that the index
tables maintained by the provider are still valid.  References must
be held on the WV provider until the IRPs finish their processing to
ensure this.

Fix invalid accesses to the IbCmId and hVerbsQp handles by locking
around their use after valid state checks.  In the case of the QP, we
add a guarded mutex for synchronization purposes and use that in place
where the PD mutex had been used.

librdmacm: fix race in ucma_init()

There's a potential race with ucma_init() and calls that check whether
the library is ready for use.  For example, in rdma_create_id, this
check is performed:

hr = cma_dev_cnt ? 0 : ucma_init();
if (hr) {
return hr;

Since the check for cma_dev_cnt is outside of any synchronization, if it
is non-zeroy, then the code will assume that initialization is complete.
However, ucma_init() can set cma_dev_cnt to non-zeroy before it has finished
executing.  The full impact of this race is unknown, but it can't be good.
In the worst case, the application may crash.

Fix this by ensuring that all initialization is complete before cma_dev_cnt
is incremented.  Note that ucma_init() provides synchronization to protect
against duplicate threads handling init.  The cma_dev_cnt check is used to
avoid synchronization on multiple calls into the library after initialization.

This patch adds usage of INLINE DATA facility of Mellanox HCAs for improving latency of ND provider.

Here are the ideas of the patch:
    - by default, ND provider will create QP with inline data of 160 bytes;
    (this can enlarge user's QP size)
    - one can change this default by defining environment variable IBNDPROV_MAX_INLINE_SIZE;
    - an ND application, while creating QP, can define the necessary INLINE DATA size; this value takes precedence over the default one.

libibverbs/comp_mgr: fix hang during destruction

The completion manager abstraction can hang during cleanup.  The hang
occurs when the user calls CompManagerCancel before calling CompManagerClose,
and the user is not waiting for events.  In this case, the completion manager
thread will pull the cancel request from the IO completion port and queue it
with the manager.  When CompManagerClose is called, it calls CompManagerCancel
to signal the thread to check the running state.  However, the completion
manager's event structure is still marked busy from the user's CompManagerCancel

The result is that the completion manager thread does not receive the
signal to check the running flag and remains asleep.  Fix this by using a
different completion entry to signal the thread during destruction than that
used to cancel a CompManagerPoll event.

This fixes occasional hangs running dapltest with both the rdma_cm and socket
cm providers.

winverbs: fix cleanup in error handling cases

Running the ndmw test results in a crash in the winverbs driver.  The
crash is caused by improper cleanup in the winverbs driver as a result
of a failure trying to allocate a memory window.

In studying the crash, the same situation could arise if other objects
also fail to be created (QPs, CQs, PDs, etc.)  To fix the crash and
simplify the code, explicit calls to used to increment the reference
count on referenced objects, rather than simply holding onto the
reference that was acquired when the object was validated.  (The latter
is slightly more efficient, but results in less maintainable code
once any fix is applied.)

  - a large built-in number of FC_EXCH QPs, which are not in use at all today.

[IBAL] remove unnecessary query_qp request during modify_qp

HCA API of modify_qp contains an optional parameter of qp_attr.
If it is coded, modify_qp makes internally a query_qp request to low-level driver and returns QP attributes.
IBAL codes this parameter, but do not use the returned QP attributes.
