color: move 'win32' declaration to the core module
This is another part of moving color implementation into core. before we can
move the advance logic, we need to move the basic definition and building
bricks. This is one more step on that road.
# Extract version number into 4 parts, some of which may be empty:
#
# version: the numeric part of the most recent tag. Will always look like 1.3.
#
# type: if an rc build, "rc", otherwise empty
#
# distance: the distance from the nearest tag, or empty if built from a tag
#
# node: the node|short hg was built from, or empty if built from a tag
