btrace: Resume recording after disconnect.
This patch allows gdbserver to continue recording after disconnect. On
reconnect, the recorded data is accessible to gdb as if no disconnect happened.
A possible application for this feature is remotely examine bugs that occur
at irregular intervals, where maintaining a gdb connection is inconvenient.
This also fixes the issue mentioned here:
