[suggestion] multiple output-formats

[wszoecs]

I really welcome the "-O summaryFormat=json" - as it allows more correct/easier parsing and processing of IOR-outputs.
BUT - as I have a lot of "legacy" parsers - I can't easily switch over to 'json' only output.

So it would be practical - to have something like "-O summaryFormat=json,default" - and have BOTH generated.

Sounds 'whacky' at first - I know - but look at FIO - it actually does the SAME! - and the idea works quite well there.
YES - it's quite 'messy' to have first text, then json (or vice versa) - but if you request 'default,json' - you know what you want.
(maybe it should even honor the order - so 'default,json' - or 'json,default' )

I still do need the human-readable text - to be able to show it to someone else.
(you can't paste a json-output into a benchmark report)

But for analyzing a large ammount of runs - having JSON additionally - would be really nice.

Good suggestion, not completely trivial.
Parsing and making it understand the requirements such as
$ ./src/ior -O "summaryFormat=json;default;CSV"
is simple. However, the log output is split across various sources. Will think about it.

Here is the patch for parsing the input, however, the refactoring for the recursive output would require a major rewrite of various parts as it is reported in line with the code and not written after an experiment is completed. One issue is that errors and output is created as soon as it is available and no information is collected and then written afterwards.
I would stop development here. Maybe someone wants to rewrite the code to collect data (it is partially existing), and then output everything after a run....
