Commit 833bd64f ("bisect: simplify the addition of new bisect terms",
29-06-2015) added a public function, read_bisect_terms(), to 'bisect.c'
which was then called by code in 'revision.c', having directly referenced
the symbol with an explicit external declaration. This causes sparse to
complain ('symbol not declared. Should it be static?').
In order to suppress the warning, move the external declaration to the
"bisect.h" header file and '#include' the header in 'revision.c'.

Hi Junio,
You recently mentioned that you may squash a fix to the 'ref-filter'
series in next whilst re-winding next. How about squashing this patch
into 'ad/bisect-cleanup' at the same time?
As you know, I have been 'up to my eyeballs' lately, so this patch is
(almost) a 'five minute quick fix' to the sparse warning. (You know that
I prefer to catch these while they are still in pu, but I missed this
one ... sorry!) So, if this patch is not appropriate (since I have not
followed any of the discussion which lead to this commit), please ignore!
BTW, a large part of 'bisect.h', namely the declartions of BISECT_SHOW_ALL,
REV_LIST_QUIET and rev_list_info are only referenced by 'builtin/rev-list.c'.
Noticed in passing ...
ATB,
Ramsay Jones
