Abstract database handle from explicit strFilename into
CWalletDBWrapper.
Also move CWallet::Backup to db.cpp - as it deals with representation
details this is a database specific operation.
This changes the logging categories to boolean flags instead of strings.
This simplifies the acceptance testing by avoiding accessing a scoped
static thread local pointer to a thread local set of strings. It
eliminates the only use of boost::thread_specific_ptr outside of
lockorder debugging.
This change allows log entries to be directed to multiple categories
and makes it easy to change the logging flags at runtime (e.g. via
an RPC, though that isn't done by this commit.)
It also eliminates the fDebug global.
Configuration of unknown logging categories now produces a warning.
Unlike Qt5, the Qt4 signals implementation doesn't allow a signal to be
directly connected to a c++ lambda expression. Work around this by defining a
Callback QObject with a virtual method that can forward calls to a closure.

Construct scoped_connection directly instead of relying on copy initialization
and move constructor. Avoids the following compile error in debian jessie:

Avoids following error when qt is statically linked into the test binary, as on
travis:
This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".
This removes the option from the wallet to not pay a fee on "small"
transactions which spend "old" inputs.
This code is no longer worth keeping around, as almost all miners
prefer not to include transactions which pay no fee at all.
- Change initializeResult(int) to initializeResult(bool) to avoid
implicit type conversion.
- Use EXIT_FAILURE and EXIT_SUCCESS instead of magic numbers.
- Remove the argument from shutdownResult(int); it was called with a
constant argument.
