This patch adds portable file IO to generic OSL to improve the portability of the applications. A portable application may use different file IO interfaces than the standard C library ones. This patch thus introduces an abstract file IO layer into the generic OSL. Note that this patch does not introduce users of such interfaces, further patches should introduce users one by one carefully with build tests performed. Lv Zheng.
