ALF-12273: Merge V4.0-BUG-FIX to HEAD

Browse Source 
33119: Merge V3.4-BUG-FIX (3.4.8) to V4.0-BUG-FIX (4.0.1)
      33099: ALF-10412 Nonreducing 100% CPU Uploading Large Files to Share Site Document Library
      ALF-10976 Excel files bigger than 2mb cause soffice.exe to take 100% of one CPU for more than 2 minutes in previews.
         - Polish TransformerDebug
         - Better config for txt and xlsx to swf   
      33095: ALF-10412 Nonreducing 100% CPU Uploading Large Files to Share Site Document Library
      ALF-10976 Excel files bigger than 2mb cause soffice.exe to take 100% of one CPU for more than 2 minutes in previews.
         - Improvements to TransformerDebug so that calls to getTransformers use trace rather than debug level logging
           allowing one to see the wood for the trees  
      33016: ALF-10412 Nonreducing 100% CPU Uploading Large Files to Share Site Document Library
      ALF-10976 Excel files bigger than 2mb cause soffice.exe to take 100% of one CPU for more than 2 minutes in previews.
         - fix build errors - may not get all of them as not tested on Linux
      33005: ALF-10412 Nonreducing 100% CPU Uploading Large Files to Share Site Document Library
      ALF-10976 Excel files bigger than 2mb cause soffice.exe to take 100% of one CPU for more than 2 minutes in previews.
         - Disable transformers if the source txt or xlsx is too large - avoids transforms that don't finish
           txt limit is 5MB
      	 xlsx limit is 1MB
         - Added a general 2 minute timeout added (ignored by JOD transformers - which already have a 2 minute timeout 
      	 and OpenOffice transformers - would require more work)
         - Previous commit already limited txt -> pdf -> png so that only the 1st pdf page was created when creating a doclib icon
         - Earlier commit already reduced the priority of the background Thread used for transformations so that user interaction
           did not suffer.
      33004: ALF-10412 Nonreducing 100% CPU Uploading Large Files to Share Site Document Library
      ALF-10976 Excel files bigger than 2mb cause soffice.exe to take 100% of one CPU for more than 2 minutes in previews.
         - Added time, size and page limits to transformer configuration to allow one to avoid
           costly transformations and to stop them if they do occur. Limits avoid a transformer being
           selected if the source is too large, or make it throw and Exception or discard data after a given
           time, KBytes read or pages created.
         - Page limits currently only used by TextToPdfContentTransformer for thumbnail (icon) creation.
         - Time, Size and Page limits are currently ignored by JodContentTransformer and OpenOfficeContentTransformerWorker
           once running but the max source size limits may be used to avoid the selection of the transformer in the first
           place.
         - TransformerDebug added to be able to see what is going on. A real eye opener!

      32136: ALF-10412 Nonreducing 100% CPU Uploading Large Files to Share Site Document Library
         Reducing the priority of the async thread pool that is used to perform the transformations so that normal activity (and even garbage collection) is not interrupted by transformations.
