[PATCH] revision.h: make show_early_output an extern which is defined in revision.c

From: Brandon Casey <casey@nrlssc.navy.mil>

Message-ID: <tafnhasVGgid37Mhftl4QXLlge-grjM8UOkw0dHIRb0@cipher.nrlssc.navy.mil>

The variable show_early_output is defined in revision.c and should be declared extern in revision.h so that the linker does not complain about multiply defined variables.
