SVN rev 197132 on 2009-09-12 19:45:55Z by bms
Tighten input checking in inp_join_group():
* Don't try to use the source address, when its family is unspecified.
* If we get a join without a source, on an existing inclusive
mode group, this is an error, as it would change the filter mode.
Fix a problem with the handling of in_mfilter for new memberships:
* Do not rely on imf being NULL; it is explicitly initialized to a
non-NULL pointer when constructing a membership.
* Explicitly initialize *imf to EX mode when the source address
is unspecified.
This fixes a problem with in_mfilter slot recycling in the join path.
