man-pages-3.10 is released

I've uploaded man-pages-3.10 into the release directory (or view the online pages). This is a fairly light release; conferences, and learning and changing my workflow for git have take a bit of time lately. Notable changes in man-pages-3.10 are:

• The clone(2) and getpid(2) pages add some notes and details of the consequences of the PID caching performed by glibc's getpid() wrapper function.
• Various changes to services(5), including removing various out-of-date pieces of text.
