ChangeLog: fix incorrect release date
darwin: fix unnecessary include headers

This file doesn't use any Cocoa functions, CoreFoundation.h is enough here.
This line causes compilation error on iOS environment.
darwin: rename darwin-getproctitle.m

Rename it to darwin-getproctitle.c, it doesn't need an Objective-C
compiler. Fix up -Wpedantic warnings about void to function pointer
casts and include <ApplicationServices/ApplicationServices.h> to get
the GetCurrentProcess() function prototype.
test: add RETURN_SKIP and RETURN_TODO macros

Added two new flags to identify tests that are intentionally ignored
(usually because we don't want to implement the tested functionality
on current platform) and test serving as TODO list (usually indicating
that the tested functionality should be implemented on current plaform
in the near future.)
Merge remote-tracking branch 'origin/v0.10'
