rcu: Update RTFP documentation
Note that this commit also updates the formatting of serveral of the bibtex entries to conform to that of my .bib files. I started accumulating entries back in the 1980s, back when bibtex insisted that comma (",") was a separator, not a terminator. This rule forced commas to the fronts of lines. 25 years later, bibtex allows commas to be terminators, but I am too lazy to rework all my .bib files. Keeping the same format as my .bib files allows my to simply incorporate my RCU.bib file into Documentation/RCU/RTFP.txt, which is much easier than my earlier practice of keeping track of what had changed and adding individual entries. (I sometimes find relevant papers that were published some years back, for example.) In addition, this change adds entries for papers published in the last year or so. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Reviewed-by: Josh Triplett <josh@joshtriplett.org>
