Changes:

• Reverts a change to SoupSession to close all open connections when the :proxy-resolver property is changed [this change was made in 2.58.0 but accidentally left out of the NEWS for that release]; although that behavior made :proxy-resolver more consistent with :proxy-uri, it ended up breaking Evolution EWS.

• Fixed undefined behavior in tests/header-parsing that could make the test spuriously fail.

• Updates to the configure tests for Apache for use in tests/:
  • Dropped support for Apache 2.2
  • Changed PHP support from PHP 5 to PHP 7
  • mod_unixd can now be either built-in or dynamically loaded
