[PATCH 5/7] gdb: move annotation_level declaration/definition to annotate.{h,c}

[Simon Marchi <simon.marchi@polymtl.ca>]

The declaration of annotation_level is currently in defs.h, while the
definition is in stack.c.  I don't really understand why that variable
would live in stack.c, it seems completely unrelated.  Move it to
annotate.c, and move the declaration to annotate.h.
