configure now enables networking, netplay LAN discovery, RetroAchievements (rcheevos)
and SSL through RetroArch's own mbedTLS (deps/mbedtls, its bundled CA certificates):
nothing new is linked from outside the tree. tools/build-retroarch.sh passes
-DHAVE_BUILTINMBEDTLS, which libretro-common's TLS socket needs and only upstream's
console makefiles pass by hand.
Name lookups: the SDK links getaddrinfo to a resolver that refuses every lookup (the
real one is in a module titles do not load) and no module exports getnameinfo.
src/net_shims.c replaces libretro-common's getaddrinfo_retro, freeaddrinfo_retro and
getnameinfo_retro (--wrap; wrapping getaddrinfo itself still bound the SDK libc's
refuser) and resolves names with the console's own DNS (libSceNet's
sceNetResolverStartNtoa); getnameinfo is numeric. Every RetroArch caller (netplay, the
lobby, HTTP, NAT traversal) reaches it; only mbedTLS's unused mbedtls_net_connect/bind
keep libc's.
Evidence: evidence/network-build (from build/llvm-pie.elf and build/ra/libretroarch.a:
the configure switches, 28 rcheevos and 60 mbedTLS objects, the 9 resolver callers,
the sceNetResolver imports, no null imports); python3 -m unittest tests.test_net_shims.
Console behaviour (sign-in, netplay) is not yet verified: no launcher was available.
Gates: bash tools/verify.sh -> verify: PASS (format unit build integration evidence)
