configure.ac:13: You should use the Autoconf-provided 'AC_PROG_MKDIR_P'

Version 1.0.3

Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers@efficios.com>

Fix: Double free when calling bt_context_remove_trace()

ctf_close_trace was being called twice when calling
bt_context_remove_trace thus causing free() to be called on an invalid
pointer.

Calling bt_context_remove_trace() would call ctf_close_trace() once via
the close_handle callback registered on the ctf format struct and a
second call would take place from bt_trace_handle_destroy() which is
registered as the value_destroy_func on the trace_handles hash table of
the current context.

bt_trace_handle_destroy() now only deallocates the trace handle and does
not perform the trace closing. This makes the
bt_trace_handle_create/destroy and bt_context_add/remove_trace parts of
the public API symmetric.
