[PATCH] Combine same ternary types in GIN and TSearch

Hi, hackers!

For historical reasons, now we have two differently named but similar
ternary data types in TSearch and Gin text-related types. Before v13 there
was also Gin's private TS_execute() version, from which we eventually
shifted to Tsearch's TS_execute().

To make things more even and beautiful I've made a minor refactor to
combine two left ternary types into one.

<gin.h>
typedef char GinTernaryValue
#define GIN_FALSE 0
#define GIN_TRUE 1
#define GIN_MAYBE 2

<ts_utils.h>
typedef enum { TS_NO, TS_YES, TS_MAYBE } TSTernaryValue;

The change is simple and most of it is just the text replacement. The only
thing worth noting is that some code does pointer cast between *bool and
*TernaryValue so the size of them should coincide. (Declaration done in
*char* type because simple enum on most architectures will be of *int*
size). There is no actual change in the code despite the order of header
files inclusion in some modules.

What do you think about this?
