4.2 branch open again

[Joseph S. Myers]

The GCC 4.2 branch is now open for commits again under normal release 
branch rules.  The official 4.2.3 release announcement will go out later 
(probably on Sunday) after mirrors have had time to update.

The next 4.2 release is likely to be in about two months' time, with 
releases continuing at two month intervals as long as some RM wishes to do 
them.  Hopefully 4.3.0 will be ready well before 4.2.4.
