new modules termcap, termcap-h

[Bruno Haible]

Another GNU package starts to make use of libtermcap [1][2]. By doing
so, it exhibits the usual portability problems:
  - It assumes that <termcap.h> exists. But these platforms don't have
    it:
    AIX, HP-UX, IRIX, Solaris, Android, Cygwin (opt.), mingw, MSVC.
  - It recognizes libtermcap and libcurses only when installed in
    system location (which in particular does not allow testing with
    the newest libncurses).

I'm adding modules 'termcap' and 'termcap-h', that fix these problems.
Taken from GNU gettext.
