Publishing the p4/p4api source code

* Find the branchspec from the previous release. The naming convention is `p4_<release>_to_workshop`.
* Copy the view from the previous release branchspec, changing the view to map from the r-line of the release you want to an area under `//depot/dev/ecosystem/p4_<release>/...`
* Create a new branch and copy in the view created in the previous step
*Run `p4 copy -b p4_<release>_to_workshop` to branch the files
* cd to the newly created directory for the branched files
* Run `jam p4` to attempt to build
* Look for errors that say "don't know how to make <somefile>". These are files that need to be added to the branchspec view.
* Add the files to the branchspec view, run the copy command again, and re-run jam. Repeat until it builds.
* Submit the files to //depot/dev/ecosystem
* Copy the files to an appropriate area in the Workshop
