PATH_MAX is not POSIX and can be missing on some systems, notably Windows (which
provides MAX_PATH instead tough) and Hurd. Let's define it to a sane value where
missing, i.e. the one it's defined to in limits.h. Except on Windows where
we're limited to 260.

Drop the ronn source files, check in the generated files instead. This gets rid
of the ruby+gem+ronn toolchain requirement at the cost of having to edit raw man
pages.
ronn files are as-generated but with the preamble and generation date removed.
The latter isn't important enough to keep, it'll just go stale for manually
maintained files and it's not worth setting up a configure_file() just for that
date.

This is the base tool, no subtools are currently connected so you only get help
and version for now. The goal here is to have a git-like infrastructure where
/usr/bin/xkbcli is the main tool, anything else will hide in libexec.
The infrastructure for this is copied from libinput. Tools themselves will
will be installed in $prefix/libexec/xkbcommon and the xkbcli tool forks
off whatever argv[1] is after modifying the PATH to include the libexec dir.
libinput has additional code for checking whether we're running this from the
builddir but it's a bit iffy and it's usefulness is limited - if you're in the
builddir anyway you can just run ./builddir/xkbcli-<toolname> directly.
So for this code here, running ./builddir/xkbcli <toolname> will execute the
one in the prefix/libexecdir.
Since we want that tool available everywhere even where some of the subtools
aren't present, we need to ifdef the getopt handling.
man page generation is handled via ronn which is a ruby program but allows
markdown for the sources. It's hidden behind a meson option to disable where
downloading ronn isn't an option. The setup is generic enough that we can add
other man-pages by just appending to the array.

Move (sometimes duplicate) the required bits into new shared files
tools-common.(c|h) that are compiled into the internal tools library. Rename the
test_foo() functions to tools_foo() and in one case just copy the code of the
keymap compile function to the tool.

Passing -errno around and having separate labels depending on failure types is
superfluous here. All the unref calls can handle NULL and nothing cares about
errno once we're out of the immediate scope. So let's simplify this and deal
with 0 and 1 only.
