686b22da6e On shutdown (job engine stop), don't allow the ObjectDisposedException on BlockingCollection.Take() to propogate if the running thread checked IsRunning before the stop thread set it and disposed of the canellation source.

86367d7219 refactor: Move methods to start a monitored thread, start work in its own thread and run work in the jobengine from Watchdog to a WorkManager class. 
This is to achieve a clean separation of concerns - the watchdog is an inappropriate place for work management.
Also adds a WorkManager.RunInThreadPool() class which feeds through to Util.FireAndForget.
Also switches around the name and obj arguments to the new RunInThread() and RunJob() methods so that the callback obj comes after the callback as seen in the SDK and elsewhere

d3ed5de77d Add loglevel to jobengine that can be controlled via "debug jobengine loglevel <level>". 
Defaults to 0
Level 1 currently does verbose logging about every queued and processed job.

9fb3065d33 Temporarily add root agent rez attachments work to job engine if it is running rather than as a fire and forget. 
Experiment to see if serializing attachment rez and send initial data jobs improves other parts of sim performance.

859b1c5ba4 Add experimental job engine to see if queueing some existing async work during root agent entry to a region improves perf rather than always attempting to execute everything concurrently 
Job engine is controlled via "debug jobengine start|stop|status".
Can only currently be enabled and disabled dynamically at runtime.
Currently only applies to code sending initial region data (objects, other avatar data) to a client.

41f2f3132b For monitoring purposes, start non-timeout tasks (which do not currently use a threadpool) via Watchdog.RunInThread() rather than Util.RunThreadNoTimeout() 
The functionality is the same but this allow us to monitor such tasks via "show threads" and abort them for test purposes, etc.
Also extends thread names to provide more info (e.g. SendInitialDataToClient says what client the task is for).

f1f935ed95 Add 'server' stats information to pCampbot, as used elsewhere in OpenSimulator 
This adds the "show stats", "stats record", etc. commands and information on available Threadpool threads, etc.
It also adds the Watchdog which logs warnings if time between executions is unexpectedly large.

cc61681484 Revert "Write UDP statistics to the log, not just the console (e.g., "show queues")" 
Fixes http://opensimulator.org/mantis/view.php?id=7280
It can't be done this way because the stats data needs to show up on the console at all log levels, not just debug.
But this means setting it to log at fatal, which is not appropriate for this stuff in the log.
I understand the desire but this has to be done some other way, perhaps by (yet another) config parameter.
Also, this was already being done with the ClientStatsReport but that also should be done in another way, I think.

This reverts commit 5d53412766.

3355bedaeb minor: Limit processor related stats to 3 decimal places instead of all the places. 
Easier to read and analyze, and probably still too much detail (1 dp would probably be fine)

200dcee1b7 Fix CPU processor use reporting on Mono. 
Despite the comments in the code, it appears that the issue where the .NET performance counter was wrongly idle time time on Mono was fixed in 2009.
https://bugzilla.novell.com/show_bug.cgi?id=468625
Which means that the workaround is no longer necessary and produces bad results instead.

8ae5ab809f Fix issue with running "stats record start|stop" console command 
In commit e6080a38 (Wed Mar 19 00:29:36 2014) I renamed this from "debug stats record start|stop"
Unfortunately, I didn't do this fully so before this commit "stats record start|stop" will report a usage failure with the old debug text.
Unfortunately this is in the 0.8 release.  The workaround is to repeat the last command twice (e.g. "stats record start start")

Disabled by default. Enable by setting
[Startup]ManagedStatsRemoteFetchURI="Something"
and thereafter "http://ServerHTTPPort/Something/" will return all the managed
stats (equivilent to "show stats all" console command).
Accepts queries "cat=", "cont=" and "stat=" to specify statistic category,
container and statistic names. The special name "all" is the default and returns
all values in that group.
