Viktor Szakats 0c327464ca tidy-up: delete parallel/unused feature flags ... Detecting headers and lib separately makes sense when headers come in variations or with extra ones, but this wasn't the case here. These were duplicate/parallel macros that we had to keep in sync with each other for a working build. This patch leaves a single macro for each of these dependencies: - Rely on `HAVE_LIBZ`, delete parallel `HAVE_ZLIB_H`. Also delete CMake logic making sure these two were in sync, along with a toggle to turn off that logic, called `CURL_SPECIAL_LIBZ`. Also delete stray `HAVE_ZLIB` defines. There is also a `USE_ZLIB` variant in `lib/config-dos.h`. This patch retains it for compatibility and deprecates it. - Rely on `USE_LIBSSH2`, delete parallel `HAVE_LIBSSH2_H`. Also delete `LIBSSH2_WIN32`, `LIBSSH2_LIBRARY` from `winbuild/MakefileBuild.vc`, these have a role when building libssh2 itself. And `CURL_USE_LIBSSH`, which had no use at all. Also delete stray `HAVE_LIBSSH2` defines. - Rely on `USE_LIBSSH`, delete parallel `HAVE_LIBSSH_LIBSSH_H`. Also delete `LIBSSH_WIN32`, `LIBSSH_LIBRARY` and `HAVE_LIBSSH` from `winbuild/MakefileBuild.vc`, these were the result of copy-pasting the libssh2 line, and were not having any use. - Delete unused `HAVE_LIBPSL_H` and `HAVE_LIBPSL`.
