Add simple buffer management code. Libevent 2.0's buffer code is not completely backward compatible with 1.4's. In order to not (mis)use it anymore, we implement it ourselves. The buffers are automatically expanding when necessary. When consuming data from the buffer, no memmove()s are performed. Only when adding to the buffer would write past the end do we shift everything back to the start. 2011-05-14 17:15:04 +00:00			`#ifndef __TINC_BUFFER_H__`
