> This patch overhauls the library loading mechanism used by the Foreign Linker > API. We realized that, while handy, the *default* lookup abstraction > (`LibraryLookup::ofDefault`) was behaving inconsistentlt across platforms. > > This patch replaces `LibraryLookup` with a simpler `SymbolLookup` > abstraction, a functional interface. Crucially, `SymbolLookup` does not > concern with library loading, only symbol lookup. For this reason, two > factories are added: > > * `SymbolLookup::loaderLookup` - which obtains a lookup that can be used to > lookup symbols in libraries loaded by current loader > * `CLinker::systemLookup` - a more stable replacement for the *default* > lookup, which looks for symbols in libc.so (or its equivalent in other > platforms). The contents of this lookup are unspecified. > > Both factories are *restricted*, so they can only be called when > `--enable-native-access` is set.
