This is related to findings in #17997 and changes network related header files to have include files outside of extern "C" { } block. Declarations that use C linkage should be placed within extern "C" so the language linkage is correct when the header is included by a C++ compiler. Similarly #include directives should be outside the extern "C" to ensure the language-specific default linkage is applied to any declarations provided by the included header.
