[2.4.8] Backport changes from 2.5 series

This commit backports changes from the 2.5 series for the 2.4.8 LTS release.
These include the following:

- [zendframework#11](zendframework#11) ensures that the
  sender can be a mailbox name, or an email specifying a host that omits the
  TLD.
- [zendframework#21](zendframework#21) provides a patch to
  allow addresses in the form `Name [email protected]` (without angle brackets
  surrounding the actual email addres).
- [zendframework#24](zendframework#24) fixes parsing of
  mail messagse that contain an initial blank line (prior to any headers), a
  situation observed in particular with GMail.
- [zendframework#26](zendframework#26) fixes the
  `ContentType` header to properly handle parameters with encoded values.
