smb: move smb_version_values to common/smbglob.h

Browse Source 
Merge the struct members of the server and the client:

  - req_capabilities:		from client
  - header_preamble_size:	from client
  - cap_unicode:		from client
  - capabilities:		from server, rename to req_capabilities
  - max_read_size:		from server
  - max_write_size:		from server
  - max_trans_size:		from server
  - max_credits:		from server
  - create_durable_size:	from server
  - create_durable_v2_size:	from server
  - create_mxac_size:		from server
  - create_disk_id_size:	from server
  - create_posix_size:		from server

Then move duplicate definitions to common header file.
