man-pages-5.04 is released

I've released man-pages-5.04. The release tarball is available on kernel.org. The browsable online pages can be found on man7.org. The Git repository for man-pages is available on kernel.org.

This release resulted from patches, bug reports, reviews, and comments from 15 contributors. The release includes approximately 80 commits that change just under 30 pages.

The most notable of the changes in man-pages-5.04 are the following:

• With some help from Christian Brauner, I've added documentation of the clone3() system call (new in Linux 5.3) to the clone(2) manual page. In addition, several other parts of the clone(2) manual page were cleaned up and reworked.
• I've refreshed the the bpf-helpers(7) page against the latest kernel sources; as a result, the page has grown size by about 25%.

Another small but important change is the addition of documentation of the P_PIDFD idtype in the waitid(2) manual page. This feature, added in Linux 5.4, allows a parent process to wait on a child process that is referred to by a PID file descriptor, and constitutes the final cornerstone in the pidfd API.
