d3cb0d99e0 Introduce two new options, "CPU private" and "no wait", to sf_buf_alloc(). 
Change the spelling of the "catch" option to be consistent with the new

private" for i386 will be committed at a later date.

d39d4a6e64 - Change the ddb paging "support" to use a variable (db_lines_per_page) to 
control the number of lines per page rather than a constant.  The variable
  can be examined and changed in ddb as '$lines'.  Setting the variable to
  0 will effectively turn off paging.
- Change db_putchar() to force out pending whitespace before outputting
  newlines and carriage returns so that one can rub out content on the
  current line via '\r     \r' type strings.
- Change the simple pager to rub out the --More-- prompt explicitly when
  the routine exits.
- Add some aliases to the simple pager to make it more compatible with
  more(1): 'e' and 'j' do a single line.  'd' does half a page, and
  'f' does a full page.
