// Load an entry point. This is really a convenience function
// which combines calls to load() and getSymbol(). However, it
// does add some value.
//
// An entry point has the following format:
//
// name[,version]:function
//
// The name of the library is constructed from the given
// information. If no version is supplied and the boolean
// argument is true, the Ice version (10 * major + minor) is
// used instead.
//
// For example, consider the following entry point:
//
// foo:create
//
// This would result in libfoo.so.11 (Unix) and foo11.dll
// (Windows), where the Ice version is 1.1.x.
//
// Now consider this entry point:
//
// foo,12:create
//
// The library names in this case are libfoo.so.12 (Unix) and
// foo12.dll (Windows).
//
// On Windows platforms, a 'd' is appended to the version for
// debug builds.
//
// Returns 0 if a failure occurred.
