ctags usability fix

Hi,

the tag file generated by the tags.sh script has some issue.

First:
The identifier-list miss the DEFINE_TRACE,EXPORT_TRACEPOINT_SYMBOL,EXPORT_TRACEPOINT_SYMBOL_GPL special handling, which can result in a wrong tag, not to jump to the right variable definition or function implementation.

Second:
It makes no real sense to include function prototypes and external and forward variable declarations, because jumping to a tag will sometimes go to this and not to the real definition and implementation. The information about the declaration is still there at the definition and implementation place.

So this patch make it lot easier to navigate through the kernel source tree using vi.

Greetings,
Stefani
