There's no such thing as a "half bet rule" in no-limit games (or pot limit games, for that matter). From Robert's Rules of Poker, Section 14 - No Limit and Pot Limit
(emphasis added by me):
3. All raises must be equal to or greater than the size of the previous bet or raise on that betting round, except for an all-in wager. Example: Player A bets 100 and player B raises to 200. Player C wishing to raise must raise at least 100 more, making the total bet at least 300. A player who has already acted and is not facing a fullsize wager may not subsequently raise an all-in bet that is less than the minimum bet or less than the full size of the last bet or raise. (The half-the-size rule for reopening the betting is for limit poker only.)
4. Multiple all-in wagers, each of an amount too small to qualify as a raise, still act as a raise and reopen the betting if the resulting wager size to a player qualifies as a raise. Example: Player A bets $100 and Player B raises $100 more, making the total bet $200. If Player C goes all in for less than $300 total (not a full $100 raise), and Player A calls, then Player B has no option to raise again, because he wasn’t fully raised. (Player A could have raised, because Player B raised.)
In your original example Player D hasn't acted at all in the hand, so he's entitled to do whatever he likes - fold, call 550, or raise to any amount between 950 and all his chips (unless he has less than 950, in which case he'd just be all in)
Player A is also entitled to re-raise if he so chooses, because Player B made a legal raise on his initial bet before Player C under-raised all in.
If either Players D or A make a legal raise (ie: to at least 950) then Player B is entitled to reraise too if he likes. If Players D and A either fold or just call the 550 though, then Player B only has the option of calling the extra 50 or folding.
Long story short: there's no such thing as a "half bet rule" in no limit or pot limit games. A bet has to be above the minimum raise to reopen the betting for players that have already acted - if it's less than the minimum, they can only call or fold.
FWIW here's the rule for limit poker (from Roberts Rules Section 3 - General Poker Rules, Betting and Raising (http://www.homepokertourney.com/roberts-rules-of-poker.htm#BETTING_AND_RAISING)):
7. In limit play, an all-in wager of less than half a bet does not reopen the betting for any player who has already acted and is in the pot for all previous bets. A player who has not yet acted (or had the betting reopened to him by another player’s action), facing an all-in wager of less than half a bet, may fold, call, or complete the wager. An all-in wager of a half a bet or more is treated as a full bet, and a player may fold, call, or make a full raise. (An example of a full raise on a $20 betting round is raising a $15 all-in bet to $35.) Multiple all-in wagers, each of an amount too small to individually qualify as a raise, still act as a raise and reopen the betting if the resulting wager size to a player qualifies as a raise.
TBH I'm not really sure why the rule is different for limit poker (I don't play much limit and I almost never have to deal it), but since the size of the bets is controlled there's a much lesser impact on the game.
