Add tan(), tanh(), log10() to std::complex
Keep the haiku/ version of the headers in sync with buildtools
(see btrev43041)

I'm curious: why do we have a copy of these headers in haiku/ tree ?

commented out hypot prototype : it conflicts with glibc signature when building libstdc++ which uses glibc headers
zooey agreed when discussing this (and we hope this don't break anything)

- added implementation of stdc++ for haiku
- this differs slightly from the one that lives in buildtools/gcc as it
has been "ported" to the newer libio that haiku uses as part of its own
