default features: make musl usable without feature test macros the old behavior of exposing nothing except plain ISO C can be obtained by defining __STRICT_ANSI__ or using a compiler option (such as -std=c99) that predefines it. the new default featureset is POSIX with XSI plus _BSD_SOURCE. any explicit feature test macros will inhibit the default. installation docs have also been updated to reflect this change.

SOL_TCP is nonstandard and not in the reserved namespace alternatively, we could define it in sys/socket.h since SO* is reserved there, and tcp.h includes sys/socket.h in extensions mode. note that SOL_TCP is simply wrong and it's only here for compatibility with broken applications. the correct argument to pass for setting TCP socket options is IPPROTO_TCP, which of course has the same value as SOL_TCP but works everywhere.

only expose struct tcphdr under _GNU_SOURCE the BSD and GNU versions of this structure differ, so exposing it in the default _BSD_SOURCE profile is possibly problematic. both versions could be simultaneously supported with anonymous unions if needed in the future, but for now, just omitting it except under _GNU_SOURCE should be safe.
