implement inline versions of some of them.
Enable only those which result roughly in the same
code size as using out-or-line versions.
None of this affects users, installed headers won't have
any trace of it.

if 256+ seconds passed since last read;
fix cases where we switch to next search domain instead of switching
to new server
optimize ip4/ip6 combined cases;
rewrite for(;;) loops so that it's clearer what's going on;
document buffer usage;
add TODOs and FIXMEs (for one, gethostbyname2 does not fill
->h_aliases field in the result AT ALL, and is iffy in general)

while keeping WCHAR support enabled. This solves two
testcases: tst_wcwidth and tst_wcswidth.

a control character: it fixes tst_iswctype test.

in cases where they clearly can't fail:
sigaction(known_good_sig)
sigprocmask(known_good_how)

fix _NSIG for it.
better document what's going on in sigaction().
seems to not induce any actual code changes (sans mips).
