Pauli 82e7b8300a Make stl_vsprintf return if there is an vsnprintf error 
vsnprintf man page claims:
"If an output error is encountered, a negative value is returned."

That means we has to call vsnprintf twice at most to have whole output
written to a string. But in case of error we return an empty string.

The code also optimizes an expected common case of outputting single
line with a small stack allocated buffer. If the stack buffer is too
small then it uses std::string::resize to allocate exactly enough memory
and writes directly to std::string.

Second call could use vsprintf because memory is known to be large
enough. But I think that difference isn't detectable outside micro
benchmarks.
