libpar2 subformula, gnutls to openssl - nzbget

As nzbget was the only formula using libpar2, have changed it into a subformula that gets installed to nzbget's libexec. Also added patches to libpar2 from nzbget, as libpar2 upstream hasn't had any activity in years. The patches are bugfixes and add the ability to cancel par2 repair. They are required for the latest nzbget.

Have moved from gnutls to openssl for nzbget, as gnutls was causing issues, and wasn't necessary when OS X provides openssl. Have tested with openssl, no issues found, and no errors that gnutls was exhibiting.

Closes #17251.

serf: depend on sqlite

apr-util will add a linkage to sqlite, even though serf doesn't use it
(from what I can tell). But when serf is linked with subversion, they
need to reference the same sqlite or bad things happen.

Closes #17172.
Add tests for ENV.with_build_environment
Add tests for ARGV.filter_for_dependencies
requirements: enable userpaths by default during evaluation
Infer path to be added for requirements that search PATH

When a requirement is specified like:

  satisfy { which "foo" }

There is no reason that we should inject all of ENV.userpaths! into the
build environment. Instead, infer the directory to be added to PATH from
the Pathname that is returned.

This is another step towards condensing the "which program" requirements
down into a one-liner DSL element.
superenv: allow -W[alp], style arguments to pass through

We already (correctly) allow -Wl, style linker arguments to pass
through; extend this to -Wp, (preprocessor) and -Wa, (assembler).

Fixes #17252.
