New maintainer target release-stats.

[Ralf Wildenhues]

This patch is purely an aid for keeping the manual up to date.
It is a bit system-dependent: you need pstops for it.  And the
output should be inspected for sanity, as some of the commands
are pretty heuristic.

Applied master and branch-1-10.

Cheers,
Ralf

    New maintainer target release-stats.
    
    * Makefile.am (release-stats): New target, to help computing the
    entries in the statistics table in automake.texi.
    * doc/automake.texi (Releases): Reformat a bit.  Add number of
    generated files.  Add entry for 1.10.1.
