Add reference count checking to make sure of good use of get and put. Add and use accessors to reduce RC_CHK clutter. The only significant issue was in tests/thread-maps-share.c where reference counts were released in the reverse order to acquisition, leading to a use after put. This was fixed by reversing the put order. Committer notes: Extracted from a larger patch removing bits that were covered by the use of pre-existing maps__ accessors (e.g. maps__nr_maps()) and new ones added (maps__refcnt()) to reduce RC_CHK_ACCESS(maps)-> source code pollution.

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.
