[avail for test] ncurses-5.3-1

[Charles Wilson <cwilson at ece dot gatech dot edu>]

I've placed updated versions of the ncurses packages on sourceware, but 
have marked them 'test'.  In order to install them, you must use setup 
and pick the 'Exp'erimental radio button on the chooser.

The new packages:
  ncurses-5.3-1
  ncurses-demo-5.3-1
  libncurses-devel-5.3-1
  libncurses7-5.3-1
  ncurses-5.3-1-src

Changes:
  o update to the 5.3 source

  o The upstream maintainer has done a lot of work to enable shared lib 
building on cygwin -- but he did it in a way completely different than 
mine.  Once I figured out what he was doing, I could see that it was 
better.  But it hasn't been as heavily tested as our version, so it is 
therefore to be treated as a "new" port.  Worse, since his approach 
differs, it means that there are ABI changes and we have to bump to '7' 
from our current ABI=6.  On the plus side, the 
non-packaging/documentation patch size has been reduced by over 75%.

  o split the monolithic ncurses-5.2-8 package into three: 
libncurses-devel-5.3-1 (link libraries and headers), ncurses-demo-5.3-1 
(the /usr/bin/ncurses-test-dll/*.exe stuff), and ncurses-5.3-1 
(everthing else: utility programs and documentation)

  o the upstream maintainer no longer supports building the C++ library 
as a sharedlib on ANY platform.  To re-enable it on cygwin, I'd have to 
seriously muck with the new build system, so I decided to withdraw the 
DLL version of libncurses++.  Naturally, any application that previously 
used it will still "get" 'cygncurses++6.dll' from the libncurses6-5.2-8 
package -- but it won't see a cygncurses++7.dll.  If you want to link a 
libncurses++-dependent package against ncurses-5.3, you'll get the 
static C++ library (but it will link against the dynamic -lncurses, 
-lpanel, -lmenu, and -lform dependencies)

  o the upstream maintainer took a different tack in fixing the 
BROKEN_LINKER problem.  The public headers no longer declare 
BROKEN_LINKER -- but they shouldn't have to, in the new scheme.

  o sigh.  ncurses_dll.h is back.  don't worry, though, it's 
automatically included.  It just offends my sense of elegance.

Please do NOT build any official packages that might depend on the new 
ncurses, until after this version has been thoroughly vetted -- BUT I'd 
appreciate build reports from official package maintainers.  <g> So, 
please build against this -- but don't release the updated packages yet.

Because setup doesn't have version-restricted dependencies, I had to put 
'libncurses7 libncurses6' in the main ncurses' setup.hint file -- which 
means that everybody is going to get the new DLLs (along with the old 
ones) even tho the new ones are marked 'test'.  Oh well.
