Add extern declarations in appropriate header files for global variables related to GUC. In many cases, this was handled quite inconsistently before, with some GUC variables declared in a header file and some only pulled in via ad-hoc extern declarations in various .c files. Also add PGDLLIMPORT qualifications to those variables. These were previously missing because src/tools/mark_pgdllimport.pl has only been used with header files. This also fixes -Wmissing-variable-declarations warnings for GUC variables (not yet part of the standard warning options).
