Bug#26780: automatic vertical output for wide results

Browse Source 
Feature from Eric Bergen, CLA signed 2007-06-27.
  
Adds new mysql client option "--auto-vertical-output", which causes
the client to test whether a result table is too wide for the current
window (where available) and emit vertical results in that case.
Otherwise, it sends normal tabular results.


client/client_priv.h:
  Add another enum value to client options, for automatic vertical output.
client/mysql.cc:
  Add another command-line option, "auto-vertical-output".
      
  Add functions to get the terminal width and functions to get the widths of fields.
      
  Use them together to emit vertical output when some output table is too wide to
  fit in the terminal.  If the terminal doesn't support reading its width, then assume
  80-positions wide.
mysql-test/r/mysql.result:
  Show that various select statements do work as expected.  Wide tables become vertical
  and narrow ones do not.
mysql-test/t/mysql.test:
  Show that various select statements do work as expected.
      
  These should be suitable for a wide range of window capabilities and sizes.  Under
  extreme circumstances, the results could be arbitrary.
