Global changes
--------------

- Man dirs:

  - Move definitions of types to separate pages in man2type/ and
    man3type/.  Previously, they were spreaded (and duplicated) in other
    pages, or in system_data_types.7 (with links in man3/).

  - Add man3head/ for pages that document header files.

  - Add man3const/ for pages that document constants.

- Licenses:

  - Use SPDX-License-Indentiffier for licenses specified by SPDX
    (including the newly-added Linux-man-pages-copyleft).  This reduces
    the overhead text at the top of most manual page source files.
    License texts have been moved to LICENSES/.

- Build system:

  - Add several make(1) targets to lint the manual pages, and also lint
    and build the C programs contained in them.  Use of these targets
    requires unreleased versions of software, such as groff-1.23.0, so
    it's not yet intended to be used by the public.

  - Add targets to build tarballs of the repository.

- man(7) source:

  - Improve consistency of man(7) source.  Also, reduce the number of
    warnings that groff(1) and mandoc(7) emit when parsing the pages
    with the highest warning level.  Most of these fixes were found
    thanks to the new `make lint-man` target.

- Manual pages sections:

  - Title (.TH):

    - Remove 5th argument to TH (middle-header).

    - Specify "Linux man-pages" and the version in the 4th argument
      (left-footer).

  - Add the LIBRARY section.  This section standardizes a way to
    document the library that provides a given interface.

  - Add the CAVEATS section.  BUGS and NOTES were serving that purpose
    before, but CAVEATS is more appropriate.

  - Rename the CONFORMING TO section to STANDARDS for consistency with
    other projects, such as the BSDs.

  - SYNOPSIS:  Add the ISO C2X [[deprecated]] attribute for functions
    that have been deprecated or removed.

  - EXAMPLES:  Improve consistency of C source code.  Also, reduce the
    number of warnings that several linting tools emit.

  - COLOPHON:  Remove section (its purpose is now served by the title).

- Repository:

  - CONTRIBUTING, README, INSTALL:  Document important changes in the
    project organization.
