Speed-up [v]s[n]printf() functions by a factor of about 2+. In
particular, sprintf(s, "%s", "") becomes faster 2.8 times,
printing of every character -- 1.7 times, and, as a result, e.g.,
printing of a string of length 50 -- 2.2 times.
* include/stream.hxx (class Cyg_OutputStream): New ABC.
(class Cyg_StdioStream): inherit from Cyg_OutputStream; make
the destructor, write(), and get_error() virtual.
* src/output/vfnprintf.cxx (vfnprintf): Use ABC Cyg_OutputStream
instead of Cyg_StdioStream.
* src/common/vsnprintf.cxx (class Cyg_VsnprintfStream): New class
that specializes Cyg_OutputStream for output to a string.
(vsnprintf): Use Cyg_VsnprintfStream for printing to a string.
