Description:

Screen is a full-screen window manager that multiplexes a physical terminal between several processes (typically interactive shells). Each virtual terminal provides the functions of a DEC VT100 terminal and, in addition, several control functions from the ANSI X3.64 (ISO 6429) and ISO 2022 standards (e.g. insert/delete line and support for multiple character sets). There is a scrollback history buffer for each virtual terminal and a copy-and-paste mechanism that allows moving text regions between windows. WWW: http://www.gnu.org/software/screen/

sysutils/screen: fix coredump on xterm/rxvt variants without Km

On xterm- and rxvt-variants (and in some other cases) screen's
InitTermcap() tries to strdup() the terminals "Km" ("key_mouse")
termcap attribute - but that might be NULL, as some of these
terminals (notably rxvt and xterm-color) do not have "Km". Trying
to strdup() NULL results in segfault and coredump.
Catch that NULL and prevent the segfault.

Install texinfo files (GNU info) into ${PREFIX}/share/info

After a discussion on the mailing list on moving manpages to
${PREFIX}/share/man for consistency with base where it is
installed in usr/share/man, it appeared the same should happen
to GNU info files which were installed under share in base and
not in ports.

Now texinfo is not in base on any of the supported version of FreeBSD
it is possible to proceed to this move and it is easier to do than
the manpage change.

Other benefit than consistency are less patching: all build tools but
cmake are expecting info files to be under share/info and cmake (patched here)
was having an exception for BSD so the patch makes FreeBSD case less
specific for them

Allow the user to select dependency on ncurses in base (USES=ncurses:base)
or devel/ncurses in ports (USES=ncurses:ports). The default option is to
depend on ncurses in ports (if installed), otherwise depend on base
(same as USES=ncurses).

This works around the following problem when screen is linked with
devel/ncurses:

$ view /etc/passwd
view: No terminal database found
$

To avoid the above problem either have screen depend on ncurses in base
or set TERM=xterm when creating new screen window.

Adding screeninfo.src from the screen tarball to terminfo.src in
devel/ncurses does not resolve this issue.

This problem does not affect packages built by poudriere.

Bjorn Zeeb discovered that screen(1) was mangling ut_host by performing
strange translations. For example, foo.bar.com gets translated to foo:S.0.
Unfortunately, this means that it also truncates IPv6 addresses,
e.g. 2001:7b8:310::1 -> 2001:S.0. Wouldn't it be better to just use the
hostname unmodified? ut_host is supposed to contain a hostname, not some
arbitrary string.
