Path code cleaning...
* Added map/path.h, moved path-related function headers to path.h. * Removed the macroed _real() path functions. * Modified some functions to use boolean return values instead of 1/0 or 0/-1. * Modified path_search_long() to allow a NULL output pointer (in which case a temporary local buffer will be used instead). * Removed an unused ->path_half member variable from struct walkpath_data. git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@11958 54d463be-8e91-2dee-dedb-b68131a5f0ec
