config options.

Nuke whitespace.

Minor mdoc fix.

Small textdump enhancements.

Allow textdumps to be called explicitly from DDB.

If "dump" is called in DDB and textdumps are enabled then abort the
dump and tell the user to turn off textdumps.

Add options TEXTDUMP_PREFERRED to turn textdumps on by default.
Add options TEXTDUMP_VERBOSE to be a bit more verbose while textdumping.
