Move the definitions of struct dm_target_io, struct dm_io and the bits of the flags field of struct mapped_device from dm.c to dm-core.h to make them usable from dm-zone.c. For the same reason, declare dec_pending() in dm-core.h after renaming it to dm_io_dec_pending(). And for symmetry of the function names, introduce the inline helper dm_io_inc_pending() instead of directly using atomic_inc() calls.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
