Rationalize "backtrace" command line parsing
The backtrace command has peculiar command-line parsing. In
particular, it splits the command line, then loops over the arguments.
If it sees a word it recognizes, like "full", it effectively drops
this word from the argument vector. Then, it pastes together the
remaining arguments, passing them on to backtrace_command_1, which in
turn passes the resulting string to parse_and_eval_long.
The documentation doesn't mention the parse_and_eval_long at all, so
it is a bit of a hidden feature that you can "bt 3*2". The strange
algorithm above also means you can "bt 3 * no-filters 2" and get 6
frames...
This patch changes backtrace's command line parsing to be a bit more
rational. Now, special words like "full" are only recognized at the
start of the command.
This also updates the documentation to describe the various bt options
individually.
