[PATCH:xts 04/16] xts5: Fix implicit declaration.

[Cyril Brulebois]

Use a forward declaration to avoid moving the function body across the
file.

The following warning goes away accordingly:
|   CC     checkevent.lo
| checkevent.c:647:10: warning: implicit declaration of function 'check_ext_event' is invalid in C99 [-Wimplicit-function-declaration]
|                 fail = check_ext_event(good,ev);
|                        ^
