Moved headers from include/libutils and include/libsysutils to libutils/include and libsysutils/include respectively, so they can be exported via these libs. They needed to be moved since Soong does not allow export from external folder. Added symlink from old locations. They are needed since Soong includes system/core/include by default. Once all modules are cleaned up to explicitly add the required libs, the symlinks will be removed. Moved headers of libutils to libutils_headers. They should be used by modules for header-only inlines. Added libutils_headers as dependency of libutils. Split of C++ headers into those that have no dependency and those that have dependency on libutils.so will be handled in a later CL. Test: Add above libs to shared lib of local module Change-Id: I122db72056b26b1f39bad1d9a0c2a1c5efda3550
