This commit was once part of "Bug 4234: Use the Firefox Update Process
for Tor Browser.".
However, some parts of it were not needed for Base Browser and some
derivative browsers.
Therefore, we extracted from that commit the parts for Tor Browser
legacy, and we add them back to the patch set with this commit.

Bug 1770484 - Make Mac processes not depend on DYLD_LIBRARY_PATH to load libraries r=glandium,gsvelto,mac-reviewers,necko-reviewers,dragana,spohl, a=dmeehan

Change XUL and other dylibs to be built with an @rpath/<dylib> install name (LC_ID_DYLIB) instead of @executable_path/<dylib>.

Change executables to be built with an @rpath dyld search path set to @executable_path by default so that @rpath/<dylib> dylibs in the same directory can be resolved. For executables not in the same directory as @rpath dylibs, such as plugin-container, set a relative @rpath such as @executable_path/../../../.

Previously, dylib install names were set as @executable_path/<dylib> allowing them to be resolved by dyld for the loading executable if the executable resided in the same directory as the dylib. For executables not in the same directory as the dylibs, dyld resolved these dylibs using DYLD_LIBRARY_PATH set before launching the process by Firefox code. With this change, loading does not rely on DYLD environment variables. Instead, dylibs have an install name set as @rpath/<dylib> and each executable loading a dylib has its @rpath set at compile-time to refer to dylib directory.
