Short circuit the BigInteger arithmetic in 'AltcoinExchangeRate' &
'org.bitcoinj.utils.ExchangeRate' (from which the former is adapted), by
using ordinary long arithmetic when it is guaranteed not to overflow due
to the two quantities to be multiplied fitting in an int. This will be
the case most of the time. Also remove duplicated logic, to ensure that
all conversions of BTC amounts to volumes happen via the 'Price'
instance methods, so that the optimisation always applies.
In particular, this speeds up the BTC -> BSQ conversions in the burning
man view, as well as the USD price calculations for the candles in the
trades charts view via 'TradeStatistics3.getTradeVolume()'.
Additionally, fix the lazy initialisation pattern in TradeStatistics3 to
ensure that it is thread safe (that is, it only has benign data races),
by making it of the form:
Foo foo = this.foo;
if (foo == null) {
this.foo = foo = computeFoo();
}
return foo;
This avoids the problem that 'foo' is a nonvolatile field and can
therefore be seen to alternate any number of times between null and
nonnull from the PoV of the thread initialising it (at least when the
initialisation is racy).
