The per-thread servent storage held std::string and std::vector
members, so getservbyname_nid_postfix registered a thread_local
destructor through __cxa_thread_atexit. On Windows that destructor runs
after emulated TLS freed the object, and prx_thread_local_destructors
(#4029) rejects libScePosixForWebKit.prx for it.
The result now lives in a thread_local struct of fixed-size char arrays
and an alias pointer array, sized for the longest name (submission),
alias (www-http), protocol (sctp) and alias count in the embedded table;
static_asserts check the sizes against the table and that the struct is
trivially destructible. The guest servent layout and the per-thread
result FreeBSD's getservent.c keeps in its NSS TLS state are unchanged.
Nothing is allocated, so the ENOMEM path is gone.
