There will be a 0.8.4 release

There have been a few not-quite-serious-enough-to-justify-a-release security fixes that, along with a couple of serious bugs, we think together DO justify a new 0.8.* release.

So I just created a 0.8.4 branch, based on the 0.8.3 branch, and will be cherry-picking from the master branch.

Planned changes from the 0.8.3 release:

Security-related: 42656ea Make RPC password resistant to timing attacks 159bc48 Simplify storage of orphan transactions, fix CVE-2013-4627 37c6389 Performance optimization for bloom filters (help mitigate potential DoS attack discussed last week)

Bug fixes: 9bf2a4ab Fix multi-block reorg transaction resurrection bf81a3ef Fix Gnome bitcoin: URI handler f0784ac4 Fix non-standard disconnected transactions causing mempool orphans 2461aba1 Mempool consistency check pull 2916 Import OSX fsync change from LevelDB subtree (will hopefully fix the random-OSX leveldb corruption issues)

There are lots of little fixes that could be included, but those will wait for the 0.9 release.
