trace: deal with deprecated glib thread functions

g_thread_create() was deprecated in favor of g_thread_new() and

trace: use glib atomic int types

Juan reported that RHEL 6.4 hosts give compiler warnings because we use

trace: Fix simple trace dropped event record for big endian

We use atomic operations to keep track of dropped events.

    of operation are not mixed or used on overlapping memory...
