MINOR: tevt/dev: Add term_events tool
This development tool can be used to convert a string representing a termination event logs to its human redable representation. Several string may be converting at a time. To do so, several arguments can be specified on the commeand line or they can be provided on STDIN, using "-" argument. Here is an exemple: > term_events f2x2f4x4 m2m4m1 e2e1 s2s1S1 E1 M1 F1 ### f2x2f4x4 : fd:shutr > xprt:shutr > fd:snd_err > xprt:snd_err ### m2m4m1 : muxc:shutr > muxc:snd_err > muxc:shutw ### e2e1 : se:eos > se:shutw ### s2s1S1 : strm:eos > strm:shutw > STRM:shutw ### E1 : SE:shutw ### M1 : MUXC:shutw ### F1 : FD:shutw The make target "dev/term_events/term_events" must be used to compile it.
