* Fix wrong thread name for wallet *relocking* thread
- Was named the unlocking thread
* Use consistent naming

NOTE: These thread names are visible in gdb when using 'info threads'.
Additionally both 'top' and 'ps' show these names *unless* told to
display the command-line instead of task name.

Use Boost's signal2 slot tracking mechanism to cancel any (still open)
listening sockets when receiving a shutdown signal.

Using this modification it should be relatively easy to, at a later
time, listen on multiple addresses (even Unix domain sockets should be
possible).

The RPC server now listens for, and handles, incoming connections on
both IPv4 as well as IPv6.
If available (and usable) it uses a dual IPv4/IPv6 socket on systems
that support it (e.g. Linux and BSDs) and falls back to separate
IPv4/IPv6 sockets on systems that don't (e.g. Windows).

This allows more flexibility in the RPC code, e.g. making it easier to
handle multiple simultaneous connections later on.
Currently asynchronous I/O is only used to listen for and accept
incoming connections. Asynchronous reading/writing is more involved.

This commit does *not* and should not modify *any* code, it only moves
it from net.h and splits it across protocol.cpp and protocol.hpp.

Move CMessageHeader from net.h to protocol.[ch]pp, with the
implementation in the .cpp compilation unit (compiling once is enough).
This commit does *not* and should not modify *any* code, it only moves
it from net.h and splits it across protocol.cpp and protocol.hpp.
Indentation changes aside the closest thing to a modification of code is
the addition of the 'TODO' comment (the execution of which requires code
modifications and thus doesn't belong in this commit).

util.h doesn't use REF, serialize.h does, creating a dependency of
serialize.h on util.h, but util.h already depends on serialize.h. To
resolve this circular dependency the function 'REF' has now been moved
closer to one of its two points of use.

Explicitly make these global variables less-global to reduce the maximum
scope of this global state.
In my experience global variables tend to be a major source of bugs. As
such the less accessible they are the less likely they are to be the
source of a bug.

Don't check for a negative parameter count, because not only will it
never happen, it doesn't make any sense either.
Invalid sockets (as returned by socket(2)) are always exactly -1 (not
just negative as negative file descriptors are technically not
prohibited by POSIX) on POSIX systems. Since we store them in SOCKET
(unsigned int), however, that really is ~0U (or MAX_UINT) which happens
to be what INVALID_SOCKET is already defined to, so an additional check
for being negative is not only unnecessary (unsigned integers aren't
*ever* negative) its redundant as well (the INVALID_SOCKET comparison is
enough).

In the assert()s take advantage of the fact that string constants
("string") are effectively of type 'const char []', which when used in
an expression yield a non-NULL pointer.
An assertion that should always fail can thus be formulated as:
assert(!"fail);
An assertion where a text message should be added to the expression can
be written as such:
assert("message" && expression);

In order to be a proper HTTP implementation clients that aren't allowed
to connect to the RPC server (using -rpcallowip), should receive a
proper HTTP response. So instead of closing the connection on them send
a '403 Forbidden' status.
