Conflict-free release note entries for GitHub pull requests

This release replaces the single documentation/RELEASE_NOTES.md file in the EPICS source tree with a mechanism that should prevent merge conflicts when new entries are added from multiple pull requests.

In this new approach each pull request adds a separate Markdown file to the documentation/new-notes directory with a unique name. All these files get combined into a single RELEASE-<version>.md file when a release is made and the new-notes directory is emptied ready for further development.

Instructions on creating new entries are provided in a README.txt file in the documentation/new-notes directory. Running make in the documentation directory will combine all the new entries into a RELEASE_NOTES.md file that then gets installed into the doc top-level directory. The make command will also install the older RELEASE-<version>.md files into that doc directory.
