None of the log pages are actually implemented yet, but at the very
least, we don't want to leak random bits of uninitialized data.

These need to be available for the lifetime of the probe_info structure,
so they can't be pointing at e.g. temporary buffers on the stack.

-Wformat-nonliteral needs to be disabled since clang triggers it on the
call to vsnprintf() now that it is nested two calls deep.

This is a counterpart to spdk_strcpy_pad() which determines the length
of a string in a fixed-size buffer that may be right-padded with a
specific character.

Record the user-provided asynchronous event configuration set via Set
Features, and return it in Get Features.
This value is not actually used, since AER is not implemented yet in the
virtual controller model, but it at least implements the mandatory
Set/Get Features.
This allows the hack in the NVMe host code that ignored the Set Features
failure to be reverted.

Fill in the cached copy of CAP in the generic NVMe controller to match
the PCIe transport.
This is not really early enough, since CAP is used during the reset
process to determine the reset timeout, but that will have to be fixed
separately by rearranging some of the transport callbacks.

- add SPDK_NVME_OPC_KEEP_ALIVE to admin_opcode
- add SPDK_NVME_SC_INVALID_SGL_OFFSET, SPDK_NVME_SC_INVALID_SGL_OFFSET,
SPDK_NVME_SC_HOSTID_INCONSISTENT_FORMAT, SPDK_NVME_SC_KEEP_ALIVE_EXPIRED
and SPDK_NVME_SC_KEEP_ALIVE_INVALID to generic_status
Make it easier to use SPDK libraries by putting them all in a single
directory that can be added with -L rather than scattered around the
source tree.

Make the public API clearer - if the user wants to allocate a
spdk_copy_task directly, they need to allocate spdk_copy_task_size()
bytes.
Also change the return type to size_t for consistency.

The SPDK_TRACELOG macro depends on a CONFIG setting (DEBUG), so it

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

Considering the process can be terminated in the cases like ctrl+c,
kill command or memory fault, the ref is tracked in the per process
structure spdk_nvme_controller_process and whenever there is other
process attaches or detaches the controller, a scan will be issued
to cleanup those unexpectedly exited processes.

These APIs can be used to register/unregister regions
of pinned, huge page memory that are separate from
huge page memory allocated by the default DPDK
allocations. These APIs will be used by an upcoming
SPDK vhost-scsi target to enable SPDK to target
NVMe DMA operations directly to VM memory that has
been allocated by QEMU using pinned huge pages.

Now that the env PCI framework already requires enumerating devices
based on an enum of specific device types, it is not useful to query the
class code of a PCI device handle.
It is currently unused and does not work in its current form on FreeBSD
(it reads a file from /sys). This lets us drop a big chunk of file
reading and parsing code.
