Introduced a gBootFrameStack that is used until the first thread structure is available - this allows stack crawls and useful register dumps during early startup. Could also be solved differently by making sure there is always a thread structure installed in %dr3 (ie. the boot thread would get a static thread structure instead of a static iframe stack only). This might be a better solution as i386_handle_trap() would no longer need to check for an existing thread structure. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12230 a95241bf-73f2-0310-859d-f6bbb57e9c96
