Test suite: Don't use DNS lookups Different operating systems do behave quite differently when doing DNS lookups, for example "127.0.0.1" sometimes resolves to "localhost" and sometimes to "localhost.localdomain" (for example OpenBSD). And other systems resolve "localhost" to the real host name (for example Cygwin). So not using DNS at all makes the test site much more portable.
Test suite: Update file headers and comments
Add support for modeless channels Add support for modeless channels (+channels). [fw@strlen.de: - integrate test cases - don't support +channels when compiled with --strict-rfc - do not set +o mode for channel creator - force +nt mode when channel is created ]
