Relocate symbol against DF_1_GLOBAL shared libraries
loaded before this shared library. This includes
main executable, ld_preloads and other libraries
that have DF_1_GLOBAL flag set.

The local group is a sequence of libraries in default (breadth-first)
order. It allows RTLD_LOCALLY loaded library to correctly relocate
symbols within its group (see test-cases).
Local group lookup is performed after main executable and ld_preloads.

Do not run symbol lookup on already visited soinfos
Not taking into account already visited libraries
dramatically slows down dlsym in cases when there
are multiple occurrences of a large library in
dependency tree.

Linker is now able to resolve symlinked libraries correctly.
soinfo is extended to save the graph of dependencies during
load/unload. Dependencies are used only in CallConstructor.
