GET Message() operation should be supported for passing below PTS
testcases -

1.MAP/MSE/MMB/BV-12-C
  Verify that the MSE can return an email message to the MCE.
2.MAP/MSE/MMB/BV-13-C
  Verify that the MSE can return a a*n* SMS message in native format
  to the MCE.
3.MAP/MSE/MMB/BV-14-C
  Verify that the MSE can return a SMS message with text trans-coded
  to UTF-8 to the MCE.

Currently get message operation is not implemented, hence above
testcases are failing.
Added code to send the complete bmessage in response to the get() request
for the requested message handle.

As per suggested in previous patch, mmap() is being used
for reading file.
