Feature request: expose __config_setting_get_int

[yshui]

config_setting_get_int returns 0 when it fails to retrieve the value, but 0 is a valid value for int. This means the caller can't distinguish successful results from failure.

__config_setting_get_int does the right thing, but is not in the public API. Same applies to other similar get functions.

config_setting_lookup_int() does what you want.

[yshui]

@hyperrealm it does not. it looks up a member of setting as int. __config_setting_get_int returns the value of setting itself.
