example, tests: address compiler warnings

Fix or silence all C compiler warnings discovered with (or without)
`PICKY_COMPILER=ON` (in CMake). This means all warnings showing up in
CI (gcc, clang, MSVS 2013/2015), in local tests on macOS (clang 14) and
Windows cross-builds using gcc (12) and llvm/clang (14/15).

Also fix the expression `nread -= nread` in `sftp_RW_nonblock.c`.

Cherry-picked from: #846
Closes #861
