Add a new per-group SUBPACKAGE option to bsd.man.mk.  When MANSPLITPKG
is enabled, this is forced to "-man", otherwise it defaults to empty
but can be overridden by the caller.

Use this in bsd.lib.mk to install library manpages in the -dev package
instead of the base package.  This is nearly always preferable, since
library manpages are usually in section 2 or 3 and are only relevant
to people with development packages installed.

For manpages which should be installed in the base package even for
libraries, add a new MANNODEV group in bsd.lib.mk.  Update existing
Makefiles to use this where appropriate.

libedit isn't as foundational as the rest of -clibs, but various bits
of -runtime do need it.  Give it a new home over in -runtime.

This also fixes the libedit build to group the readline bits into the
same package as the libedit that implements them.

After the recent import, explicit set of WARNS=3 is not needed.

Remove ancient SCCS tags from the tree, automated scripting, with two
minor fixup to keep things compiling. All the common forms in the tree

Without this patch, sh can autocomplete file names but not commands from
$PATH. Use libedit's facility to execute custom function for autocomplete,
but yield to the library's standard autocomplete function when cursor is
not at position 0.

A few shared libraries in the base system link against ncurses.  An
upgrade from a 12.x host to 13 results in ABI breakage for existing
binaries since the newer versions of these libraries link against the
newer ncurses while the binary itself links against the older ncurses.
For example, dialog4ports built on 12.x sometimes crashes on 13 since
it depends on libdialog which links against ncurses internally.

This version bring many fixes regarding unicode support
It also adds proper support for filename completion (we do not need our custom
patches anymore)
Improves the libreadline compatibility

Note that the same work was done by Yuichiro Naito in
https://reviews.freebsd.org/D21196 the main difference is in this case we have
reimported libedit in contrib to fix a long standing mess in the previous merges
which prevented a proper update workflow. (discussed long ago with pfg@)

The only difference with upstream libedit is we have added a compatibility shim
for the _elf_fn_sh_complete function which we previously added to support quoting
in filename completion and is not needed anymore.
This was added to continue supported old /bin/sh binaries and not break backward
compatibility (as discussed with jilles@)
