Added likely() and unlikely() branch prediction hint macros
to syshead.h Introduced BUF_MAX constant to limit struct buffer offset and length values. BUF_MAX has been set to 2^20. Use likely() and unlikely() macros in buffer.h code to allow the compiler to generate more efficient code. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3058 e7ae566f-a301-0410-adde-c780ea21d3b5
