[LOG4NET-487] Control mutex type

• Type: Improvement
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 1.2.14, 1.3.0
• Component/s: Appenders

Description

The only missing feature is an option for choosing Local (per session) or Global (per machine) mutex.
The current code just uses the filename for mutex which good but it always makes a local one, so if you have two sessions you cannot synchronize them.
Default is Local for backward compatibility.

See Note in: https://msdn.microsoft.com/en-us/library/system.threading.mutex%28v=vs.110%29.aspx
I think it can be an option like

<RollingMutexType value="Global" />
or something like that.

It also applies to FileAppender mutex .
<LockingModel InterProcessLock>
<LockingMutexType value="Global" />
</..>

See issue #485 for reference.
