The patch removes all macros in the format
define xf86_sym ((type (*)(argument-list))LoaderSymbol("sym"))
creates a new macro in the format
define xf86_sym sym
and ensures "sym" is a "visible" symbol.
The patch doesn't add or remove features, and is source and binary
compatible with previous shared objects (with the difference that it
requires the dlloader).
These symbols are a special case, as, due to the fact that LoaderSymbol
was being used to reference them, they are not easily found by "automated"
tools that check for missing symbols. And now it also have the benefit
that the compiler/loader "knows what is going on".
