Log message:

Communicate traces to userspace through shared memory instead of
copying.
* module/sysprof-module.c: Store the traces in a SysprofMmapArea.
(sysprof_mmap): Implement this method.
(sysprof_nopage): Implement this.
(sysprof_read): Just reset the tail pointer and return zero.
* module/sysprof-module.h (struct SysprofMmapArea): New
structure.
* collector.c (collector_stop): Unmap the device
(in_dead_period): New function
(on_read): Read the traces out of mmap()ed area instead of reading
them. Call read() to prevent poll() from firing.
(struct Collector): New members map_area and current.
* Makefile.am (insert-module): Prefix modprobe with /sbin
* collector.c (open_fd): mmap() the sysprof device.
