- Update the wrapper script to 'release.sh', as used by the FreeBSD

Release Engineering Team as of 9.2-RELEASE.

- Document that a cross-build release is possible by setting the
  TARGET and TARGET_ARCH variables.

- Include an example of using release.sh with and without the
  optional configuration file.

- Document the supported release.sh configuration file variables.

- Update the 'cdrom' target output file to disc1.iso.

- Update the 'memstick' target output file to memstick.img.

- Add attributions for the last major updates to this manual page.

- Fix some mdoc(7) style nits:
  - Sentences should begin on a new line
  - Use .Pq to enclose full lines in parenthesis
