perf tools: Add call-graph option support into .perfconfig
Adding call-graph option support into .perfconfig file, so it's now
possible use call-graph option like:
[top]
call-graph = fp
[record]
call-graph = dwarf,8192
Above options ONLY setup the unwind method. To enable perf record/top to
actually use it the command line option -g/-G must be specified.
The --call-graph option overloads .perfconfig setup.
Assuming above configuration:
$ perf record -g ls
- enables dwarf unwind with user stack size dump 8192 bytes
$ perf top -G
- enables frame pointer unwind
$ perf record --call-graph=fp ls
- enables frame pointer unwind
$ perf top --call-graph=dwarf,4096 ls
- enables dwarf unwind with user stack size dump 4096 bytes
