branches.  `Early adopter' branches will be supported 6+ months,
`Normal' branches will be supported 12+ months, and `Extended'
branches will be supported 24+ months.

Mark RELENG_4_8 as an `Extended' support branch and extend its
Estimated EoL accordingly.

While here, also extend RELENG_5_2 through the end of 2004.

(I was reminded that RELENG_4_8 had expired a few days ago by
cperciva@.)
