This will help with things like tools/lib/string.c where we want to have more things in common with the kernel, such as strim(), skip_spaces(), etc so as to go on removing the things that we have in tools/perf/util/ and instead using the code in the kernel, indirectly and removing things like EXPORT_SYMBOL(), etc, getting notified when fixes and improvements are made to the original code. Hopefully this also should help with reducing the difference of code hosted in tools/ to the one in the kernel proper.

We need to audit the usage of argv_split() to figure out if it is really necessary to do have one allocation per argv[] entry, looking at one of its users I guess that is not the case and we probably are even leaking those allocations by not using argv_free() judiciously, for later. With this we further remove stuff from tools/perf/util/, reducing the perf specific codebase and encouraging other tools/ code to use these routines so as to keep the style and constructs used with the kernel.

Print output data (and output context if relevant) into a file or into the console. Print return value and duration for the test run into the console. A "repeat" argument can be passed to run the program several times in a row. The command does not perform any kind of verification based on program type (Is this program type allowed to use an input context?) or on data consistency (Can I work with empty input data?), this is left to the kernel. Example invocation: # perl -e 'print "\x0" x 14' | ./bpftool prog run \ pinned /sys/fs/bpf/sample_ret0 \ data_in - data_out - repeat 5 0000000 0000 0000 0000 0000 0000 0000 0000 | ........ ...... Return value: 0, duration (average): 260ns When one of data_in or ctx_in is "-", bpftool reads from standard input, in binary format. Other formats (JSON, hexdump) might be supported (via an optional command line keyword like "data_fmt_in") in the future if relevant, but this would require doing more parsing in bpftool. v2: - Fix argument names for function check_single_stdin().
