QPID-7926: [c++ broker] Windows build error "cannot convert from 'int' to
'qpid::sys::PODMutex'"
Renamed PODMutex as GlobalMutex. The important point is that it can be used as a
global variable. In POSIX we use a POD class and static initializer to acomplish
this, but on windows we use boost::recursive_mutex, which is documented as being
safe for use as a global variable.
Modified the QPID_MUTEX_INITIALIZER macro to be empty on windows and '= { 0 }'
on POSIX.
This closes #11

> 1>D:\Users\crolke\git\qpid-cpp\src\qpid\log\Logger.cpp(48): error C2440:
> 'initializing' : cannot convert from 'int' to 'qpid::sys::PODMutex'
> 1> No constructor could take the source type, or constructor
> overload resolution was ambiguous
> {noformat}
> The issue is with the definition of QPID_MUTEX_INITIALIZER.
> In Linux it is defined as PTHREAD_MUTEX_INITIALIZER which is a complex
> structure initializer.
> In Windows it is a naked 0.
> In a stand-alone windows program
> {noformat}
> std::is_pod<PODMutex>::value
> {noformat}
> returns false. In Linux the same statement in qpidd broker returns true.
