man-pages-3.24 is released

I've uploaded man-pages-3.24 into the release directory (or view the online pages). The most notable changes in man-pages-3.24 are the following:

• The addition of three pages by David Howells describing the kernel key management facility: add_key(2), request_key(2), and keyctl(2). (These pages were formerly part of the keyutils package.)
• The fcntl(2) manual pages adds documention of F_SETOWN_EX and F_GETOWN_EX, which are new in Linux 2.6.32.
• Minor changes to many other pages.
