[GitHub] trafficserver pull request #1381: Lib Scalar

Lib Scalar

Scalar is a header only library. It provides typed numeric values that have 
a scaling factor. The "value" of a scalar is its count multiplied by its scale. 
The primary benefits are

* The scaling factor is explicit and carried with the type.
* Conversions between scaled values are automatic or rejected by the 
compiler.
* Explicit conversions indicate rounding up or down.
* Conversions are as fast as possible, compiling down to single multiplies 
or divides if one scale is a multiple of the other. If the scales are powers of 
two the conversions are compiled down to shift operations.

This is currently being tested in work on the cache, using Scalar to 
represent the various size values in the cache. This provides simple 
conversions and compiler warnings when scales don't match.
