Move jsonapi.c and jsonapi.h to src/common.
To make this work, (1) makeJsonLexContextCstringLen now takes theencoding to be used as an argument; (2) check_stack_depth() is made todo nothing in frontend code, and (3) elog(ERROR, ...) is changed topg_log_fatal + exit in frontend code.Mark Dilger, reviewed and slightly revised by me.Discussion:http://postgr.es/m/CA+TgmoYfOXhd27MUDGioVh6QtpD0C1K-f6ObSA10AWiHBAL5bA@mail.gmail.com
