Version 1.4

This release introduces the -R / blind-req option, whose probable sole
purpose is to request the userhost-in-names capability on freenode,
where it is available but not advertised in response to CAP LS.

This release no longer depends on LibreSSL's libcrypto for compatibility
with systems other than FreeBSD. LibreTLS[1] can now be used to provide
libtls rather than LibreSSL.

This release implements compatibility with broken clients that send
commands terminated with only LF, rather than CR LF as the specs
describe.

Certificates generated with -A and -g are now properly signed.

The configure script is now used on all platforms, and depends on
pkgconf or pkg-config.
