Add setting feature that can add config variables with their values to a
config file (i.e. user or system config file) or modify config key-value
pairs in a config file. For the syntax examples:
perf config [<file-option>] [section.name[=value] ...]
e.g. You can set the ui.show-headers to false with
# perf config ui.show-headers=false
If you want to add or modify several config items, you can do like
# perf config annotate.show_nr_jumps=false kmem.default=slab
Committer notes:
Testing it:
$ perf config -l
top.children=true
report.children=false
$
$ perf config top.children=false
$ perf config -l
top.children=false
report.children=false
$
$ perf config kmem.default=slab
$ perf config -l
top.children=false
report.children=false
kmem.default=slab
