This adds extensive HTTP/2 test coverage using libnghttp2 as the test server, covering multiplexing, stream error handling, connection management, and settings negotiation. * tests/libtest.h (wget_test_url_t): Add h2_delay_response and h2_rst_stream_error fields for HTTP/2 test control. (WGET_TEST_H2_MIN_CONCURRENT_STREAMS): New test flag. (wget_test_get_h2_server_port): Declare function. * tests/libtest.c: Remove HAVE_MICROHTTPD_HTTP2_H infrastructure, (h2_session_data, h2_server_t): New structures for libnghttp2 server, (h2_send_callback, h2_recv_callback): Implement nghttp2 I/O callbacks, (h2_on_frame_recv_callback): Handle HTTP/2 frames, (h2_on_header_callback): Process request headers, (h2_data_read_callback): Stream response body with 8KB chunk limit, (h2_on_stream_close_callback): Clean up stream resources, (h2_session_data_new, h2_session_data_free): Manage session lifecycle, (h2_server_thread): Main server loop with TLS and ALPN support, (h2_server_start, h2_server_stop): Control server lifecycle, (_http_server_stop): Remove gnutls_global_deinit() call to fix server restart issues, (wget_test_start_server_handler): Default start_h2 to 0 (opt-in), enable HTTP/2 with WGET_TEST_H2_ONLY flag, (wget_test): Skip H2_PASS when libnghttp2 unavailable, (wget_test_get_h2_server_port): Return HTTP/2 server port. * tests/Makefile.am (WGET_TESTS): Add test-http2-multiplexing, test-http2-stream-errors, test-http2-connection-errors, test-http2-settings. * tests/test-http2-multiplexing.c: New file testing concurrent downloads over single HTTP/2 connection with multiplexing. * tests/test-http2-stream-errors.c: New file testing stream error isolation with RST_STREAM frames. * tests/test-http2-connection-errors.c: New file testing connection recovery after server restart. * tests/test-http2-settings.c: New file testing SETTINGS frame exchange, header compression, and large headers. * tests/test-limit-rate-http2.c (main): Skip 3-file multiplexed download test when running with HTTP/2 due to rate limiting limitations in test server. The HTTP/2 test server uses libnghttp2 with GnuTLS for TLS and ALPN negotiation. Tests verify protocol-specific features like multiplexing, stream independence, and proper SETTINGS exchange. HTTP/2 is now opt-in via WGET_TEST_H2_ONLY to avoid breaking existing tests.
