* glib/grand.c, gthread/gthread-impl.c, tests/rand-test.c:
Improved the seeding algorithm. Old behaviour can be achived by
setting envvar G_RANDOM_VERSION to "2.0". (#99262)
* docs/reference/glib/glib-docs.sgml,
docs/reference/glib/Makefile.am: Renamed
docs/reference/glib/changes-2.0.sgml to
docs/reference/glib/changes.sgml and added section for changes
from 2.0 to 2.2 (Also corrected 1.0 to 1.2).
* README.in, docs/reference/glib/running.sgml,
docs/reference/glib/tmpl/random_numbers.sgml,
docs/reference/glib/changes.sgml: Added notes about the new
seeding algorithm.
