Among other things makes the symbols consistent across all architectures (notably where ldbl mantissa is 53 bits). While at it, kill unused LINTLIBRARY/PROTOLIB1 cruft which was there to trick lint into recording the right prototypes for aliased functions. Most of the work done at the awesome n2k13 hackathon. Agreed by kettenis@, guenther@, matthew@. Get rid of the very ugly lint workarounds: LINTLIBRARY, PROTOLIB, 2013-01-13T03:44:59Z martynas martynas@openbsd.org 2013-01-13T03:44:59Z urn:sha1:bec2cc9ed0f86f0319e7da7794f847fd97d09187 and a few empty files for lint to chew on.
