65470e5c7d changing lock mechanism
Systems can suffer power interruptions whilst .lock files are in /etc,
preventing scripts and other automation tools from updating shadow's
files which persist across boots.

This commit replaces that mechanism with file locking to avoid problems
of power interruption/crashing.

Minor tweak to groupmems man page, requested by 'xx' on IRC.

408b8a5482 Use the lckpwdf() again if prefix is not set
The implementation of prefix option dropped the use of lckpwdf().
However that is incorrect as other tools manipulating the shadow passwords
such as PAM use lckpwdf() and do not know anything about the
shadow's own locking mechanism.

This reverts the implementation to use lckpwdf() if prefix option
is not used.

e15fbb905c * NEWS, lib/getdef.c, man/login.defs.5.xml: New login.defs
variable: MAX_MEMBERS_PER_GROUP. Used for the split groups support.
* lib/commonio.c, lib/commonio.h: Add an open_hook and close_hook
  operation. They are called after the database is actually opened
  and parse, or before it is closed.
* lib/groupio.c: Add an open_hook to merge split groups, and an
  close group to split groups if MAX_MEMBERS_PER_GROUP is set.
  This fixes gpasswd and chgpasswd when split groups are used.
* lib/sgroupio.c, lib/shadowio.c, lib/pwio.c: No open or close
  hooks for these databases. (unsure about what should be the gshadow
  behavior for split groups)
