[PATCH] i386: multi-column stack backtraces
Print stack backtraces in multiple columns, saving screen space. Number of
columns is configurable and defaults to one so behavior is
backwards-compatible.
Also removes the brackets around addresses when printing more
that one entry per line so they print as:
<address>
instead of:
[<address>]
This helps multiple entries fit better on one line.
Original idea by Dave Jones, taken from x86_64.
