Proposal: cmStringAlgorithms: Add cmToStr class for formatted numeric to string conversion

Sebastian Holtermann requested to merge sebholt/cmake:cmStringAlgorithms_cmToStr into master

The new class cmToStr in cmStringAlgorithms.h allows to convert numeric types to a formatted std::string. Its purpose is to replace std::ostringstream for formatting numbers in CMake.

Example 1: Single formatted number

  std::ostringstream v;
  v << std::setfill('0') << std::setw(4) << this->XcodeVersion * 10;
  return v.str();

can be replaced by

  return cmToStr().Fill('0').Width(4).Get(this->XcodeVersion * 10);

Example 2: Hexadecimal number

  std::ostringstream v;
  v << std::setbase(16) << std::setfill('0') << "     "
    << "0x" << std::setw(8) << number;
  return v.str()

can be replaced by

  return cmToStr().Hex().Fill('0').ShowBase().Width(8).Get(number);
