dbdcb7be99 Remove UAREA_PAGES and USPACE definitions. The definitions of 
USPACE_SVC_STACK_TOP, USPACE_SVC_STACK_BOTTOM, USPACE_UNDEF_STACK_TOP,
and USPACE_UNDEF_STACK_BOTTOM look wrong to me, so I'm leaving them
alone.

799ea28b61 Remove some references to U area here while trying not to break 
anything.  Someone with ARM hardware could do a lot more to untangle
this code.

279c442e7b 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
options.  Implement the "no wait" option.  An implementation of the "CPU
private" for i386 will be committed at a later date.

a9860ec891 - 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.
