Doug Moore 504f5e294e swap_pager.c reserves 2 blocks for a bsd label. Change that 2 to the
expression howmany(BBSIZE, PAGE_SIZE), where BBSIZE is the size of the
boot block area.  That can be less than 2 if PAGE_SIZE is big.

swapon(8) has an option to trim (delete) all the blocks of a device at
startup.  However, if the first of those blocks is a bsd label, then
trimming those blocks is destructive.  Change swapon to leave the
first BBSIZE bytes untrimmed.

Update manual pages to reflect changes in how swapon and how it may be
used, espeically in association with savecore.
