Bug 1249389 - part 6 - provide UniquePtr overload for nsIStartupCache::GetBuffer; r=erahm The lone remaining startup cache-related uses of nsAutoArrayPtr are both in TestStartupCache.cpp, for use with nsIStartupCache::GetBuffer. The uses can't use StartupCache::GetBuffer because StartupCache::GetBuffer isn't visible outside of libxul, and TestStartupCache is a normal C++ unit test. The Right Thing is to convert TestStartupCache to a gtest so we can see libxul internal symbols and then delete nsIStartupCache entirely. That's a bit complicated, as TestStartupCache doesn't fit nicely into gtest's framework. The simpler solution is to add a UniquePtr overload in the interface that hides the XPCOM outparam management details.
