Steve French 3d1a3745d8 Add sparse file support to SMB2/SMB3 mounts ... Many Linux filesystes make a file "sparse" when extending a file with ftruncate. This does work for CIFS to Samba (only) but not for SMB2/SMB3 (to Samba or Windows) since there is a "set sparse" fsctl which is supposed to be sent to mark a file as sparse. This patch marks a file as sparse by sending this simple set sparse fsctl if it is extended more than 2 pages. It has been tested to Windows 8.1, Samba and various SMB2/SMB3 servers which do support setting sparse (and MacOS which does not appear to support the fsctl yet). If a server share does not support setting a file as sparse, then we do not retry setting sparse on that share. The disk space savings for sparse files can be quite large (even more significant on Windows servers than Samba).
