Subject: [PATCH v4 0/5] perf tools: Add 'perf-config' command

So far, it is difficult that the state of perf configs is looked through
and there's no knowing what kind of other variables except variables in perfconfig.example.
Also perf configs can't be changed without manually modifying $HOME/.perfconfig or
$(sysconfdir)/perfconfig file. So I suggest this patchset of the perf-config command
which can list, get, set, remove perf configs or list with default config values as below.

[PATCH v4 1/5] perf tools: Add 'perf-config' command
[PATCH v4 2/5] perf config: Add '--system' and '--global' options to
       	       	    	    select which config file to be used
[PATCH v4 3/5] perf config: Add functions which can get or set perf config variables
[PATCH v4 4/5] perf config: Add a option 'list-all' to perf-config
[PATCH v4 5/5] perf config: Add a option 'remove' to perf-config

Changes in v4:
	- If some config value is default value, notice it is '(default)'
	as suggested by Jirka. (PATCH v4 3/5)

	- If there wasn't any perfconfig file, perf-config malfunctioned like
	Jirka pointed out. So add exception routine with '--global' and '--system'
	option which can select perf config file path. (PATCH v4 2/5)

Changes in v3:
	- Add a config variable 'kmem.default' with a default value as suggested by Namhyung.
	(PATCH v3 2/5, PATCH v4 3/5)

Changes in v2:
	- Change option name of listing all configs as '--list-all' instead of '--all'
	as suggested by Namhyung. (PATCH v2 3/4, PATCH v4 4/5)

	- Correct small infelicities or typing errors in a perf-config documention
	as suggested by Arnaldo. (PATCH v2 1/4, PATCH v4 1/5)

	- Declaration a global variable 'static struct default_configsets' has config variables
	with default values instead of using a 'util/PERFCONFIG-DEFAULT' file.
	(PATCH v2 3/4, PATCH v4 3/5)

	- Add a function to normalize a value and check data type of it.
	(PATCH v2 2/4, PATCH v4 3/5)

	- Simplify parsing arguments as arguments is just divided by '=' and then
	in front of '.' is a section, between '.' and '=' is a name, and behind '=' is a value.
	(PATCH v2 2/4, PATCH v4 3/5)

	- If run perf-config command without any option, perf-config work as '--list'.
	(PATCH v2 1/4, PATCH v4 1/5)
