b58a5d73ef util: add SPDK_COUNTOF() array size macro
SPDK_COUNTOF works like sizeof, except it returns the number of elements
in an array instead of the number of bytes.

0801877b7d nvmf,direct: add AER support in direct mode.
After checking the code, aerl in our session is 0,
so there will be only 1 AER. So currently,
we will only handle 1 AER case.

When the AER event is triggered by real NVMe device owned
by the subsystem, it notifies all sessions belonging to
the subsystem.

async event configuration like virtual mode instead of
passthrough.

d27b24c94b log: split internal TRACELOG macro into new header
The SPDK_TRACELOG macro depends on a CONFIG setting (DEBUG), so it
should not be part of the public API.

Create a new include/spdk_internal directory for headers that should
only be used within SPDK, not exported for public use.

0b252a7000 Revert "nvmf: only poll admin queue once every 10 ms"
This is causing issues during shutdown because the poller removal is not
synchronized with the rest of the cleanup path.

This reverts commit 7dfc5e922d.
