I committed those fixes to the "xam-fixes" project (vim.cpp) and also
added tests to the simple unit test I wrote (C_XAM_Library/test/http-
test.cpp).
Methods fixed are:
* XSystem_GetXSetAccessTime
* XSystem_AccessXSet
* XSystem_CopyXSet
* XSystem_HoldXSet
* XSystem_ReleaseXSet
* XSystem_DeleteXSet
* XSystem_isXSetRetained
* XSystem_AsyncOpenXSet (not tested)
* XSystem_AsyncCopyXSet (not tested)
I didn't test the last two because I haven't the time to invent more
testing framework for them. They'll probably get tested at some point.
