This patch is for DIF check types.
Add enum spdk_dif_check_type to DIF library.
Add a field dif_check_flags to struct spdk_bdev and add
spdk_bdev_is_dif_check_enabled to bdev APIs.
Added enum is intended to improve usability. If no enum, the
caller will have to get raw data of flags and mask each bit.

To support DIF, bdev will need to expose the following information:
- Metadata format
- Block size
- Metadata size
- Metadata setting (interleave or separate)
- DIF settings
- DIF type 1, 2, or 3
- DIF location
- DIF check types
- Guard check
- Reference tag check
- Application tag check
This patch is for the metadata format. Subsequent patches will do for the DIF
setting and DIF check types.
Add fields, md_len and md_interleave, to struct spdk_bdev and add APIs,
spdk_bdev_get_md_size and spdk_bdev_is_md_interleaved, to bdev APIs.
The fields, md_len and md_interleave, are added to the bdev JSON infomation dump.
DIF will be used only in the NVMe bdev module and the upcoming virtual
DIF bdev module first. But additional required storage by md_len and md_interleave
will be very small and they are simple. Hence add them to struct spdk_bdev simply.

Vhost external events no longer do any asynchronous
calls, they only lock the vhost mutex and directly
call the provided function. The mutex encapsulation
isn't worth the additional complexity of splitting
each vdev-handling code into multiple functions, so
we expose low-level APIs that should eventually
replace external events entirely.
Instead of:
```
static int do_something_cb(struct spdk_vhost_dev *vdev, void *arg)
{
struct my_data *ctx = arg;
/* access the vdev and ctx */
free(ctx);
}
struct my_data *ctx = calloc(...);
rc = spdk_vhost_call_external_event("my_vdev", do_something_cb, ctx);
if (rc != 0) { /* err handling */ }
```
We can now do just:
```
spdk_vhost_lock();
vdev = spdk_vhost_dev_find("my_vdev");
if (vdev == NULL) { /* err handling */ }
/* access the vdev any context data */
spdk_vhost_unlock();
```

Error check of strtol is left to users of it. But some use cases
of strtol in SPDK do not have enough error check yet.
For example, strtol returns 0 if there were no digits at all.
It should be avoided for each use case to add enough error checking
for strtol.
Hence spdk_strtol and spdk_strtoll do additional error checking
according to the description of manual of strtol.
Besides, there is no use case of negative number now, and to keep
simplicity, spdk_trtol and spdk_strtoll allows only strings that
is positive number or zero.
As a result of this policy, callers of them only have to check if
the return value is not negative.
Subsequent patches will replace atoi to spdk_strtol because atoi
does not have error check.

There are some patches to linux kernel for separating
out discard IOs that are written to /proc/diskstats and
the various /sys/block/*/stat files. The following additional
fields were added to these files:
Filed 12 -- # of discards completed
Filed 13 -- # of discards merged
Filed 14 -- # of sectors discarded
Filed 15 -- # of millisecond spent discarding
SPDK could provide these raw information to bdev_io_stat. Users
can use these information to calculate more states of block device.

This follows the same trend as the mem_map APIs.
Currently, most of the spdk_vtophys() callers manually
detect physically noncontiguous buffers to split them
into multiple physically contiguous chunks. This patch
is a first step towards encapsulating most of that logic
in a single place - in spdk_vtophys() itself.
This patch doesn't change any functionality on its own,
it only extends the API.

For write operations, copy data to req->buf and write
to disk.
If chunk already specified in logical map, read the
chunk first into req->buf, and overwrite with data
specified by the write operation.
If chunk not specified in logical map, fill logical
blocks not specified by the write operation with
zeroes.
For read operations, read chunk into req->buf first,
then copy relevant data into the buffers specified
by the read operations.
These operations are all functional, but have room
for future improvement. For example, this patch
will issue a separate backing read/write operations
for each backing block in the chunk - this could be
optimized to coalesce operations where the backing
blocks are contiguous.
While here, clean up freeing bufspace in one of

This follows the overall model introduced together
with PCI device hooks. Having an additional set of
attach/enumerate/hook functions for each device type
doesn't scale well. We can simplify this by moving
the driver-agnostic attach and enumerate functions to
the public headers. It'll be used directly by the
upcoming VMD driver.

Devices behind a VMD aren't visible directly on the PCI
bus. In order to support them, we'll need an additional
VMD driver that's going to enumerate the devices behind
it and hook those into the SPDK PCI layer.
We want those devices to be accessible with the same APIs
that are used to access physical PCI devices.
The physical devices are still created and managed by
DPDK, but additional devices can be now hooked externally.
The hook API slightly departs from how env layer worked
so far. Instead of keeping the generic hook functions
internal-only and adding per-driver (NVMe, I/OAT, Virtio)
public functions, this patch makes the generic hook API
public from the start. It accepts the device driver as
a parameter, which needs to be exposed now. That's why
spdk_pci_nvme_get_driver() is introduced. It's only the
NVMe driver that's exposed so far, but other drivers and
their attach APIs should eventually follow the same path.
The previous model really didn't scale well and there's
no need to stretch it further.

In order to populate our PCI device list with devices
located behind the VMD, we'll need to fill out those
device structures from within a special VMD driver. That
driver will base on PCI configuration and BAR accesses,
but definitely not on DPDK. We want to put the VMD driver
outside of the env lib, so we provide it with a direct
access to the device struct.

Currently the API requires the caller to open the
pmem file and pass the mapped buffer pointer, length
and pmem flag to libreduce using the spdk_reduce_pm_file
structure.
Let's have the library just do the pmem_map_file() instead.
Users then just pass the path to create the pmem file. The
library will still use the spdk_reduce_pm_file structure
internally - so move its definition out of the public header
and into reduce.c.
