Subject: [ANNOUNCE] trace-cmd v2.7

Features since 2.6:

 - Add "--quiet" (-q) to trace-cmd record to surpress output

 - trace-cmd stat has some more data

 - trace-cmd record splice() how handles more than one page

 - Add --module filtering option to associate modules to filters

 - New -O offset for function plugin

 - Bash completion for -O options.

 - Bash completion for -B instance buffers

 - New trace-cmd clear to simply clear out the trace-cmd buffers

And lots of internal churn to prepare for bigger features in the
future.
