Benjamin Smedberg bb1c33c4ea Bug 488175 - flatten dist/include and provide mechanism to install certain headers in namespaced subdirectories (e.g. #include "mozilla/XPCOM.h") r=ted
--HG--
rename : xpcom/ds/nsTimeStamp.cpp => xpcom/ds/TimeStamp.cpp
rename : xpcom/ds/nsTimeStamp.h => xpcom/ds/TimeStamp.h
