I'm not sure cannon answers this explicitly but my take is this:

  Pureblood: magical from the beginning of time. (Weasleys, Malfoys)

  Halfblood: any combination of non pure-pure or muggle-muggle 
parentage. 
     Pure-Muggle: Tom/LV
     Pure-Half: ?
     Half-Half: ?
     Pure-Mud: Harry (though James could have been a half)
     Mud-Mud: ?

  Mudblood: both parents muggle (Hermione)

  Squib: a pure or half blood with no magical powers

  Muggle: muggle born muggle.

  An interesting question would be if a pureblood squib married a 
pureblood would the child be considered a pureblood if it wasn' a 
squib also?
