Split JSON lexer/parser from 'json' data type support.
Keep the code that pertains to the 'json' data type in json.c, but
move the lexing and parsing code to a new file jsonapi.c, a name
I chose because the corresponding prototypes are in jsonapi.h.
This seems like a logical division, because the JSON lexer and parser
are also used by the 'jsonb' data type, but the SQL-callable functions
in json.c are a separate thing. Also, the new jsonapi.c file needs to
include far fewer header files than json.c, which seems like a good
sign that this is an appropriate place to insert an abstraction
boundary. I took the opportunity to remove a few apparently-unneeded
includes from json.c at the same time.
Patch by me, reviewed by David Steele, Mark Dilger, and Andrew
Dunstan. The previous commit was, too, but I forgot to note it
in the commit message.
