Add libkrbd libtool convenience library to provide an interface for
mapping and unmapping rbd images programmatically. This will be used
by the rbd binary itself and the librbd_fsx testing tool.
libkrbd takes care of the kernel module stuff (common/module.h) and
makes use of libudev to be able to properly wait for block device
creation and deletion and tell which block device got assigned by the
kernel to the newly created mapping.

strerror_r is not portable; on Gnu libc it returns char * and sometimes
does not fill in the supplied buffer. Use autoconf to test which
version this platform uses and adapt.
Clean up the random calls to strerror and strerror_r (along with all
their private little one-use buffers) and regularize the code to use
cpp_strerror almost everywhere. Where changed, any negation of the
error code is also removed, since cpp_strerror() will do that.
Note: some tools were using their own calls to strerror/strerror_r, so
will now get a (%d) in their output that wasn't there before; hence
the change to test/cli/monmaptool/print-nonexistent.t

When configured with --without-libxfs, use GenericFileStoreBackend

Adds a ceph_spinlock_t implementation that will use pthread_spinlock_t
if available, and otherwise reverts to pthread_mutex_t. Note that this
spinlock is not intended to be used in process-shared memory.
Switches implementation in:
ceph_context
SimpleMessenger
atomic_t
Only ceph_context initialized its spinlock with PTHREAD_PROCESS_SHARED.
However, there does not appear to be any instance in which CephContext
is allocated in shared memory, and thus can use the default private
memory space behavior.

Currently the way 'rbd unmap' translates a user-provided block device
into an rbd id is it matches the major number of the specified device
against /sys/bus/rbd/devices/<id>/major for each rbd mapping and
declares success on the first match. This works for both entire disks
and partitions, because under the current device number allocation
scheme, each mapping means a new major number.
In preparation for support for single-major device number allocation
scheme, which would require matching both major and minor numbers, make
sure to always match against entire disk device numbers, by converting
the specified device major:minor pair into wholdedisk major:minor pair.
To achive that, use the libblkid library, which accomplishes this goal
by walking stable sysfs structures.

Checking for fdatasync uses the same approach as the qemu configure
script. The relevant commit is d1722a27f552a22561104210e0afad4577878e53.
Here is a copy of the commit message which explains the check:
Under Darwin, a symbol exists for the fdatasync() function, so that our
link test succeeds. However _POSIX_SYNCHRONIZED_IO is set to '-1'.
According to POSIX:2008, a value of -1 means the feature is not
supported.
A value of 0 means supported at compilation time, and a value greater 0
means supported at both compilation and run time.
Enable fdatasync() only if _POSIX_SYNCHRONIZED_IO is '>0'.

Make sure the requested length is below the maximum pipe size for now,
since we're only using one pipe and splicing once into and out of
it. The default max is 1MB on recent kernels, so this isn't such a
terrible limitation.
To get around this we could use multiple pipes, or keep both source and
destination fds open at the same time and call splice many times. This
is more usual usage for splice, but would require a lot more work to
restructure the filestore and messenger to handle it.

This involves three pieces:
For intrusive_ptr type references, we use TrackedIntPtr instead. This
uses get_with_id and put_with_id to associate an id and backtrace with
each particular ref instance.
For refs taken via direct calls to get() and put(), get and put now
require a tag string. The PG tracks individual ref counts for each tag
as well as the total.
Finally, PGs register/unregister themselves on construction/destruction
with OSDService.
As a result, on shutdown, we can check for live pgs and determine where
the references are held.
This behavior is compiled out by default, but can be included with the
--enable-pgrefdebugging flag.
