Bump version numbers to prep for 0.8.4 release
Fix Gnome bitcoin: URI handler
Fix multi-block reorg transaction resurrection
Make RPC password resistant to timing attacks

Fixes issue#2838; this is a tweaked version of pull#2845 that
should not leak the length of the password and is more generic,
in case we run into other situations where we need
timing-attack-resistant comparisons.
Revert "Truncate oversize 'tx' messages before relaying/storing."

This reverts commit 7cc960f8f57e7fe90ee7aa0ccd3e3c6c89ec5a25.
Simplify storage of orphan transactions

Orphan transactions were stored as a CDataStream pointer;
this changes the mapOrphanTransactions data structures to
store orphans as a CTransaction.

This also fixes CVE-2013-4627 by always re-serializing
transactions before relaying them.

Merge commit '6519339fe849bdbbff047d9eef8ab6c5fbb3e2a4'
Performance optimization for bloom filters.

This reduces a peer's ability to attack network resources by
 using a full bloom filter, but without reducing the usability
 of bloom filters.  It sets a default match everything filter
 for peers and it generalizes a prior optimization to
 cover more cases.
fixed: include boost header as necessary

Without this include, sometimes BOOST_VERSION was defined and sometimes
it was not, depending on which includes came before it. The result was a
random mix of sleep or sleep_for for boost versions >= 1.50.
fixed: don't use thread::sleep_for where it's known to be broken

Fixes #2690.

Update the bloom state on the real object, not the temporary one.

This resulted in just passing all transactions to filtered wallets
which worked surprisingly well, except where it didn't.
