Subject: Add a new WTAP_ERR_DECOMPRESS error, and use that for errors
 discovered by the gunzipping code.  Have it also supply a err_info string,
 and report it.  Have file_error() supply an err_info string.

Put "the file" - or, for WTAP_ERR_DECOMPRESS, "the compressed file", to
suggest a decompression error - into the rawshark and tshark errors,
along the lines of what other programs print.

Fix a case in the Netscaler code where we weren't fetching the error
code on a read failure.
