trace-cmd: Version 3.1.3

Updates since version 3.1.2:

 - Fixes to the host/guest agent communication

 - Update to documentation

 - Cleanups to Makefiles

 - Updates to the testing (utest)

 - Convert trace-cmd reead to use some of the library helpers instead
   of open coding it.

 - Have trace-cmd read -F affect the last -i file and not just the first one.

 - Have trace-cmd read use the new tep_plugin_kvm_get_func() callback
   (If the library does not define it, it will simply be ignored).

Minor feature enhancements: (not enough to change the extra version number)

 - Add --notimeout option to allow agend and record to not timeout if
   the other end is doing debugging (via gdb). --debug already does this
   but this option is to not need full debugging, but to just tell the
   other end not to error out on timeout.

 - Add --compression to extract (the feature was there, but the option was not).
