3684	"Add ""chunked"" upload mode"	Gubaer	team	"JOSM currently supports two upload modes:
  1.  one request per created/updated/deleted object
  2.  one request for the whole dataset to upload

For large dataset something between these two would be nice. JOSM could split up the dataset to upload into manageable ""chunks"" and upload these chunks. This would be more efficent than (1) and more robust than (2).

The ""chunk size"" could be a parameter to select in the upload dialog and users could select between
  * individual object upload in multiple requests
  * chunked upload in multiple requests
  * upload in one request
