* Rewrote headers as necessary; only Errors.h and Debug.h still originate from a Be header now;
feel free to change that ;-) * Cleaned up existing headers. * Coding style guide update to BBufferIO (renamed m_* members to f*). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19972 a95241bf-73f2-0310-859d-f6bbb57e9c96
