Subject: Add ability to dump cpu boost log to disk, include thread names

0.) B 0 /rockbox/apps/main.c:405
1.) B 1 /rockbox/firmware/kernel/thread.c thread[dircache]:1508
2.) B 2 /rockbox/apps/tagcache.c:4772
3.) U 3 /rockbox/apps/tagcache.c:4793

add logic to show count after log rolls over
clean-up
