[PATCH v3 07/15] Write trace notes and username into tfile.

[Yao Qi <yao@codesourcery.com>]

The fields "notes" and "user_name" in "struct trace_status" are used
in the output of "tstatus".  When in tfile target, the "notes" and
"user name" are missing the output of "tstatus", because GDB doesn't
write them into tfile.  With this patch, GDB starts to write them into
tfile, and the corresponding information will be shown when GDB reads
trace status from the tfile target.

	* tracepoint.c (tfile_write_status): Write trace notes and user
	name into tfile if they are not NULL.
