Use thread_local statics in dtoa.c to be thread-safe

We don't use MULTIPLE_THREADS for that to avoid performance
penalty due to locking and memory allocation.

Use dtoa.cxx stub to compile dtoa.c as C++, to allow using
thread_local keyword in MSVC, which still implements pre-C99.

Also don't expose dtoa() and other symbols - make them static.
And define IEEE_MC68k, not IEEE_8087 on big endian platforms.
