Next patch will introduce enum spdk_dif_check_type for user to
know easily if checking DIF field is enabled or not.
This patch renames bitmask macros from SPDK_DIF_*_CHECK to
SPDK_DIF_FLAGS_*_CHECK to avoid mis-interpretation .
Using FLAGS was derived from SPDK_NVME_IO_FLAGS_PRCHK_* in
include/spdk/nvme_spec.h.

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.

Imagine the following code flow:
1. `spdk_put_io_channel();`
2. `spdk_io_device_unregister();`
Since putting an io_channel is always deferred,
it is likely that spdk_io_device_unregister will
lock the io_channel mutex first. It will set
dev->unregistered flag and then quickly realize
there are still open channels for this device
(refcnt > 0) - so it'll return. All fine here.
However, if the deferred put_io_channel happens to
lock the mutex first from other thread, it will
decrement the refcnt and attempt to free the device.
Both the decrementation and freeing are done under
a mutex, but there is a slight window inbetween
where the mutex is re-locked. spdk_io_device_unregister
is already sleeping on a mutex_lock(), so it might
strike now. It'll see there are no more io_channels
for this device and free the device. Once
put_io_channels regains the lock again, it will attempt
freeing the device for a second time.
This patch removes the slight window mentioned above.

Previously, there was a period of time where the user
had put the last reference to a channel, but when
calling to get a new channel would end up with the
previously created channel and channel destruction
would never execute.
This causes a number of unexpected issues to pop up,
as often the creation and destruction of a channel
is a key event.

The unregister callback is only invoked after all I/O channels related
to the I/O device have been freed. The last I/O channel to be freed
might be on a thread different than the thread where spdk_io_device_unregister
was called. If this is the case, send an event to the latter thread
so that the callback gets called on the same thread as spdk_io_device_unregister.

We must keep the lock held after removing the io_ch from the thread
before iterating the list of threads to check for other channels
referencing this thread. Without it, it is possible for two different
threads to think they are the last thread holding a reference to
an unregistered device, and both will call the unregister_cb and free
the dev memory.

Fixes github issue #218.
This patch introduces spdk_cpuset object to store and manipulate
the set of individual CPUs. The main objective of this object is
to replace cpumask declared as uint64_t and extend the limitation
of supported CPUs (lcores) above 64 CPUs.
spdk_cpuset is always allocated dynamically and accessed by opaque
pointer, what makes it easier to extend in the future without
breaking API/ABI.
This patch also extends parsing function allowing to set cpumask
using a list of cpus e.g. "[0-4,10,12]" sets mask of 0,1,2,3,4,10,12
as well as hexadecimal string with and without "0x" prefix.

This is a very hot function in the main I/O path,

To avoid application changes with how the g_devlist_mutex is
held, it is no longer held while calling
_spdk_io_device_attempt_free() because the app unload CB is
called from that function and may want to call
spdk_io_device_unregister() from its unload CB. So the lock
is now held and releases strictly around the list its
protecting which allows the CB from _spdk_io_device_attempt_free()

-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.

This allows users to swap their PCI library from
libpciaccess/dpdk to another mechanism using the standard
method for swapping out the env library.

This allows users to swap out SPDK's third party
libraries for an implementation based on their own
framework.

This patch also drops support for automatically unbinding
devices from the kernel - run scripts/setup.sh first.
Our generic pci interface is now hidden behind include/spdk/pci.h
and implemented in lib/util/pci.c. We no longer wrap the calls
in nvme_impl.h or ioat_impl.h. The implementation now only uses
DPDK and the libpciaccess dependency has been removed. If using
a version of DPDK earlier than 16.07, enumerating devices
by class code isn't available and only Intel SSDs will be
discovered. DPDK 16.07 adds enumeration by class code and all
NVMe devices will be correctly discovered.

Some subsystems may wish to create unique I/O channels
which are not shared across all users of the same I/O
device on the same thread.

This patch adds a basic framework for creating I/O channels
for I/O devices. An spdk_io_channel represents a one-to-one
mapping between a calling thread (represented by spdk_thread)
and an I/O device that the thread will perform I/O operations
on.

The out-of-bounds case in the bit array accessors should not happen
normally, so help the compiler order the basic blocks correctly so that
the in-bounds case is the fallthrough path.
