text output helps kernel developer trace the kernel directly.

text output include these:

1) Marker ID management
   Marker ID identify every type of event,
   a) ASCII text output needs get name&fmt from eID faster.
   b) Marker ID and its data must be permanent.

patches:
	01/13: make marker_entry permanent
	02/13: get name and fmt from permanent eID

2) ltt-relay events traveling

patches:
	07/13: implement fmt align
	11/13: implement ltt-ascii (the core patch for text output)

3) event reader
   get significative binary data from event. and convert them to a va_list
   or other type. binary in event is raw data, we must know its meaning for
   formating.

patches:
	03/13: read event header from ltt-relay buffer
	07/13: implement fmt align  (skip pending data)
	04/13: read C-style string from ltt-relay buffer
	05/13: read basic type from  ltt-relay buffer

4) event text formator
   format data to text.

patches:
	06/13: introduce ltt_serialize_printf()
	11/13: implement ltt-ascii

5) create files for text output and control
	11/13: implement ltt-ascii
	12/13: enable text output for ltt-relay
	13/13: enable text output for ltt-relay-locked

6) misc
	08/13: get&put chan&chan_buf's reference
	09/13: enable accessing struct ltt_channel_buf_struct
	10/13: implement text output framework
	11/13: implement ltt-ascii
