Michael Roth 173bbb754f qapi: String visitor, use %f representation for floats
Currently string-output-visitor formats floats as %g, which is nice in
that trailing 0's are automatically truncated, but otherwise this causes
some issues:

 - it uses 6 significant figures instead of 6 decimal places, which
   means something like 155777.5 (which even has an exact floating point
   representation) will be rounded to 155778 when converted to a string.

 - output will be presented in scientific notation when the normalized
   form requires a 10^x multiplier. Not a huge deal, but arguably less
   readable for command-line arguments.

 - due to using scientific notation for numbers requiring more than 6
   significant figures, instead of hard-defined decimal places, it
   fails a lot of the test-visitor-serialization unit tests for floats.

Instead, let's just use %f, which is what the QJSON and the QMP visitors
use.

Paolo Bonzini a020f9809c qapi: add string-based visitors
String based visitors provide a consistent interface for parsing
strings to C values, as well as consuming C values as strings.
They will be used to parse command-line options.
