Buffet: utility function tweaks
Various tweakes to helper functions and classes, split off from
a larger CL that required them.
1. Added Error::AddToPrintf to help add formatted error messages.
2. Added Error::GetFirstError to get the innermost error occurred.
3. Added string_utils::ToString and swept code using std::to_string
in order to ensure we format doubles correctly (using %g instead
of %f format specifier) and bool values (using "true"/"false"
instead of 1/0).
4. Fixed C-style cast in http_utils.h and using static_cast now.
5. Fixed a few linter warnings. Also since the linter was updated
there is no reason to have some NOLINT since many C++11 features
are now recognized properly by cpplint.
BUG=None
TEST=All unit tests pass.
