net/mlx5: support device removal event

Extend the LSC event handling to support the device removal as well.

The mlx5 event handling has been made capable of receiving and
signaling several event types at once.

This support includes next:
1. Removal event detection according to the user configuration.
2. Calling to all registered mlx5 removal callbacks.
3. Capabilities extension to include removal interrupt handling.

net/mlx5: link status update separation

Link status is sometimes inconsistent during a LSC event.
When it occurs, the PMD refrains from immediately notifying
the application; instead, an alarm is scheduled to check
link status later and notify the application once it has settled.

In the previous code the alarm callback calls to the interrupt
handler for link status recheck and may cause to unnecessary
interrupt events check.

This patch separates the link status update and the interrupt event
handler to avoid the unnecessary check and arranges the interrupt
handler for more interrupt supports in the future.

Comment was added in the new function to explain the inconsistent
link status reason.

pci: increase domain storage to 32 bits

In some environments, the PCI domain can be larger than 16 bits.
For example, a PCI device passed through in Azure gets a synthetic domain
id which is internally generated based on GUID. The PCI standard does
not restrict domain to be 16 bits.

This change breaks ABI for API's that expose PCI address structure.

The printf format for PCI remains unchanged, so that on most
systems (with only 16 bit domain) the output format is unchanged
and is 4 characters wide. For example: 0000:00:01.0
Only on sysetms with higher bits will the domain take up more
space; example: 12000:00:01.0

ConnectX-5 supports enhanced version of multi-packet send (MPS). An MPS Tx
descriptor can carry multiple packets either by including pointers of

better utilize PCIe bandwidth. In addition, Enhanced MPS supports hybrid
mode - mixing inlined packets and pointers in a descriptor. This feature is
