Deduplicate a number of files used by extensions by moving them to the public directory (bug 5341, r=psychonic).

These files include smsdk_ext.cpp, smsdk_ext.h, sm_memtable.h, CDetour/*, and asm/*.
The smsdk_config.h file for each extension has also been moved out of the 'sdk' directory into its parent.
