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. --HG-- rename : extensions/bintools/sdk/smsdk_config.h => extensions/bintools/smsdk_config.h rename : extensions/clientprefs/sdk/smsdk_config.h => extensions/clientprefs/smsdk_config.h rename : extensions/cstrike/sdk/smsdk_config.h => extensions/cstrike/smsdk_config.h rename : extensions/curl/sdk/smsdk_config.h => extensions/curl/smsdk_config.h rename : extensions/geoip/sdk/smsdk_config.h => extensions/geoip/smsdk_config.h rename : extensions/mysql/sdk/smsdk_config.h => extensions/mysql/smsdk_config.h rename : extensions/regex/sdk/smsdk_config.h => extensions/regex/smsdk_config.h rename : extensions/sdkhooks/sdk/smsdk_config.h => extensions/sdkhooks/smsdk_config.h rename : extensions/sdktools/sdk/smsdk_config.h => extensions/sdktools/smsdk_config.h rename : extensions/sqlite/sdk/smsdk_config.h => extensions/sqlite/smsdk_config.h rename : extensions/structs/sdk/smsdk_config.h => extensions/structs/smsdk_config.h rename : extensions/tf2/sdk/smsdk_config.h => extensions/tf2/smsdk_config.h rename : extensions/topmenus/sdk/smsdk_config.h => extensions/topmenus/smsdk_config.h rename : extensions/updater/sdk/smsdk_config.h => extensions/updater/smsdk_config.h rename : extensions/sdktools/CDetour/detourhelpers.h => public/CDetour/detourhelpers.h rename : extensions/sdktools/CDetour/detours.cpp => public/CDetour/detours.cpp rename : extensions/sdktools/CDetour/detours.h => public/CDetour/detours.h rename : extensions/sdktools/asm/asm.c => public/asm/asm.c rename : extensions/sdktools/asm/asm.h => public/asm/asm.h rename : public/sample_ext/sdk/smsdk_config.h => public/sample_ext/smsdk_config.h rename : core/logic/sm_memtable.h => public/sm_memtable.h rename : public/sample_ext/sdk/smsdk_ext.cpp => public/smsdk_ext.cpp rename : public/sample_ext/sdk/smsdk_ext.h => public/smsdk_ext.h
