linker: hide the pointer to soinfo
Handle no longer is a pointer to soinfo of
a corresponding library. This is done to
prevent access to linker internal fields.

Count references for groups instead of instances
Count references on the group level to avoid
partially unloading function that might be
referenced by other libraries in the local_group
Bonus: with this change we can correctly unload recursively
linked libraries. is_recursive check is removed.
Also dynamic executables (not .so) with 0 DT_NEEDED libraries
are now correctly linked.

Fix symbol lookup order during relocation

main executable, ld_preloads and other libraries

Fix relocation to look for symbols in local group
The local group is a sequence of libraries in default (breadth-first)
