The struct perf_evsel_config_term::val is a union which contains fields 'callgraph', 'drv_cfg' and 'branch' as string pointers. This leads to the complex code logic for handling every type's string separately, and it's hard to release string as a general way. This patch refactors the structure to add a common field 'str' in the 'val' union as string pointer and remove the other three fields 'callgraph', 'drv_cfg' and 'branch'. Without passing field name, the patch simplifies the string handling with macro ADD_CONFIG_TERM_STR() for string pointer assignment. This patch fixes multiple warnings of line over 80 characters detected by checkpatch tool.
