This commit replaces all those fiddly little linking modules (be_all.c, be_none.c, be_ssh.c etc) with a single source file controlled by ifdefs, and introduces a function be_list() in setup.cmake that makes it easy to compile a version of it appropriate to each application. This is a net reduction in code according to 'git diff --stat', even though I've introduced more comments. It also gets rid of another pile of annoying little source files in the top-level directory that didn't deserve to take up so much room in 'ls'. More concretely, doing this has some maintenance advantages. Centralisation means less to maintain (e.g. n_ui_backends is worked out once in a way that makes sense everywhere), and also, 'appname' can now be reliably set per program. Previously, some programs got the wrong appname due to sharing the same linking module (e.g. Plink had appname="PuTTY"), which was a latent bug that would have manifested if I'd wanted to reuse the same string in another context. One thing I've changed in this rework is that Windows pterm no longer has the ConPTY backend in its backends[]: it now has an empty one. The special be_conpty.c module shouldn't really have been there in the first place: it was used in the very earliest uncommitted drafts of the ConPTY work, where I was using another method of selecting that backend, but now that Windows pterm has a dedicated backend_vt_from_conf() that refers to conpty_backend by name, it has no need to live in backends[] at all, just as it doesn't have to in Unix pterm.
This is the README for PuTTY, a free Windows and Unix Telnet and SSH
client.
PuTTY is built using CMake <https://cmake.org/>. To compile in the
simplest way (on any of Linux, Windows or Mac), run these commands in
the source directory:
cmake .
cmake --build .
Documentation (in various formats including Windows Help and Unix
`man' pages) is built from the Halibut (`.but') files in the `doc'
subdirectory using `doc/Makefile'. If you aren't using one of our
source snapshots, you'll need to do this yourself. Halibut can be
found at <https://www.chiark.greenend.org.uk/~sgtatham/halibut/>.

reports saying `it doesn't work' will waste your time as much as
ours.
