lib/stream: add float/double <-> IEEE-754 single/double mux/demuxers
* stream.{c,h}: Add stream_get{f,d} and stream_put{f,d}) demux and muxers to
safely convert between big-endian IEEE-754 single and double binary
format, as used in IETF RFCs, and C99. Implementation depends on host
using __STDC_IEC_559__, which should be everything we care about. Should
correctly error out otherwise.
Thanks to Aidan Delaney <aidan@phoric.eu> and Olivier Dugeon for pointing
out the __STDC_IEC_559__ macro.
Update: GCC does not per se set __STDC_IEC_559__, so also test for
__GCC_IEC_559 >= 1.
