V5 -> V6:
datetime.c:
 Move comment line "There are three 100-year periods worth of leap
  days (3*24)" down one line.
 Change order of terms in 'days' calculation to be more readable.
date_unit_test.c:
 Correct comment to "Leap year, after Feb" instead of "prior to Feb"
Add "reviewed by" from Daniel Kiper for patches with permission.

V4 -> V5:
datetime.c / h:
 Rename variables "is_bisextile" to "bisextile".
 Change some boolean assignments to use ternary operator.
 Compare booleans to true instead of checking "if(boolean)".
date_unit_test.c:
 Add additional commentary to the tests array for meaning of numbers.
 Rework test ranges to cover from years 0001 to 9999 and add specific
 min/max tests for min 0001 date and max 9999 date.

V3 -> V4: Add additional commentary for a few magic numbers
 and fix some coding standard issues.

V2 -> V3: Added additional commentary to datetime.c to describe
 the origin of some of the numbers used in calculations.
