Hide warnings from Python headers when using gcc-compatible compiler.
Like commit 388e80132, use "#pragma GCC system_header" to silence warnings appearing within the Python headers, since newer Python versions no longer worry about some restrictions we still use like -Wdeclaration-after-statement. This patch improves on 388e80132 by inventing a separate wrapper header file, allowing the pragma to be tightly scoped to just the Python headers and not other stuff we have laying about in plpython.h. I applied the same technique to plperl for the same reason: the original patch suppressed warnings for a good deal of our own code, not only the Perl headers. Like the previous commit, back-patch to supported branches. Peter Eisentraut and Tom Lane Discussion: https://postgr.es/m/ae523163-6d2a-4b81-a875-832e48dec502@eisentraut.org
