What about providing --no-opt for multi purposes?

There are many needs to add more options to switch off some of options.
Here are the list of --no- prefixed options.

$ uftrace --help | grep "\-\-no\-"
      --no-comment           Don't show comments of returned functions
      --no-event             Disable (default) events
      --no-libcall           Don't trace library function calls
      --no-merge             Don't merge leaf functions
      --no-pager             Do not use pager
      --no-pltbind           Do not bind dynamic symbols (LD_BIND_NOT)
      --no-randomize-addr    Disable ASLR (Address Space Layout Randomization)

We could provide a new option to embrace all those with --no-opt=OPT[,OPT,...] and it can be used as follows.

$ uftrace replay --no-opt=event,libcall,pager

It's the same as following options:

$ uftrace replay --no-event --no-libcall --no-pager

Taking advantage of general purpose --no-opt, we can better add more switches without worrying about increasing the number of options.

The possible candidates are as follows:

• --no-opt=args to hide arguments/return values (uftrace: Add --no-args option to hide args/retval #595)
• --no-opt=sched to turn off scheduling event (schedule event needs to be fixed #739)
• and many more...

--no-opt=OPT could be renamed to any other such as --no=OPT or --turn-off=OPT or we can also reuse --disable to --disable=OPT.

--opt-off=OPT could be a good candidate as well if --opt-on=OPT is also planed to be used.

I'm considering to change option parse code, maybe we can discuss it later.

I also think it'd be better. Thanks.
