Make it much easier to test a configuration built without readline support, by reusing our existing library probe machinery. It gets a bit tricky with readline, which does not provide a pkg-config snippet, and which on some platforms requires one of several terminal libraries as a prerequiste, but the end result should be the same default behavior but now with the option to disable things. * m4/virt-readline.m4 (LIBVIRT_CHECK_READLINE): Simplify by using LIBVIRT_CHECK_LIB. * tools/virsh.c: Convert USE_READLINE to WITH_READLINE.
