perf_counter tools: Add new OPT_CALLBACK_DEFAULT option
There is no predefined macro to create an option that can have a custom value or a default one if none is given. This patch provides a new helper OPT_CALLBACK_DEFAULT() which defines such kind of option. For example, considering an option -c, we want to get the default value in the following cases: perf command -c -d perf command -d -c And the foo value when it's given: perf command -c foo -d perf command -d -c foo That's also why PARSE_OPT_LASTARG_DEFAULT is extended here to support default values whatever the position of the option, not only in the end. Should it now be renamed to PARSE_OPT_ARG_DEFAULT ?
