Remove unnecessary NULL check before free()
Merge pull request #315 from hsin919/master

Bug fix
Replaced #317 - `NSGregorianCalendar` deprecated in iOS8 and Mac OS X 10.10 replaced with `NSCalendarIdentifierGregorian `. Could not check for availabilty of the constant directly, since it is defined earlier, but not available for iOS
Replaced #312 - `aslresponse_next` and `aslresponse_free` deprecated, replaced with `asl_next` and `asl_release`
- Updated a Podfile.lock for the CaptureASL project
Merge pull request #320 from bpoplauschi/fixed_deprecations

Fixed deprecations
Bumped podspec version to 1.9.2
Removed all the "C" log macros (as suggested in #220). By replacing sel_getName(_cmd) with __PRETTY_FUNCTION__, there is not need for the separation of Obj-C and C macros.
Updated the Mobile libtest project to demonstrate that it's working (had to use a formatter so the function/method names are used).
Replaced sel_getName(_cmd) with __PRETTY_FUNCTION__, as it was supposed to be (lost in some rebase).
