At the same time replace old OSL_TRACE, OSL_FAIL, OSL_ENSURE
with SAL_* as appropriate:

OSL_TRACE =--> SAL_LOG or =--> SAL_WARN if requires some kind of
attention by the developer.

OSL_FAIL =--> SAL_WARN or =--> SAL_INFO if the warning is brought up
later in the program flow.

OSL_ENSURE =--> assert oe SAL_WARN_IF when appropriate.
