[PATCH v2 6/6] error: move XlogGapError to box/error.h

All box exceptions belong to box/error.h. Let's move XlogGapError there
as well. This will facilitate conversion of recovery.cc to C when we
finally get to it. While we are at it, let's also move BuildXlogError
function declaration from diag.h to box/error.h, closer to its
definition.
