There's no need to export this symbol, so mark them all hidden.

They expand into the same code, but using the ELF_xxx()/ElfW() macros
makes it much easier to spot similarities between code bases.

Protected symbols are global symbols for which interposition is not allowed.
We manage them in generic _dl_lookup_hash function. To handle protected symbols
we need to get a reference to the module that defines the symbol itself.
So we pass a new parameter 'struct symbol_ref' to the __dl_lookup_hash
that is defined as below:
struct symbol_ref {
const ElfW(Sym) *sym;
struct elf_resolve *tpnt;
};
The tpnt field is used as an ouput parameter and refers to the module which defines
the protected symbol.
Further it can be used as output parameter for TLS relocations and FDPIC case.
The sym field is instead used as an input parameter to detect the visibility of the
symbol we are looking-up.
In this way we get rid of different signatures for _dl_lookup_hash, allowing to remove
the _dl_find_hash wrapper.
This new structure is also suitable for prelink integration.

Update Arch specific part of the dynamic linker to the
latest cahnges required by prelink:
- Use _dl_loaded_modules->scope as global symbol scope
- Pass the sym argument (or NULL) to the _dl_find_hash
- Update _dl_parse, _dl_do_reloc, _dl_do_lazy_reloc and
_dl_parse_relocation_information to reflect the change of
the scope argument's type
- Add the call to _dl_debug_lookup used for trace prelinking.

With TLS _dl_find_hash grew an extra param.
These archs don't have TLS reloc support yet, but they do need to
compile without it.

Some powerpc machines can support 64k pages, enabled by the
CONFIG_64K_PAGES option in linux.
However, the uClibc dynamic loader won't currently work on these
machines, as it uses hard-coded values (PAGE_ALIGN, ADDR_ALIGN and
OFFS_ALIGN) in the ldso architecture-specific headers. When running on
a kernel with 64k pages, ld.so tries to mmap with 4k-aligned addresses,
rather than 64k, so mmap fails with -EINVAL.
When booting a 64k machine with a uClibc dynamic linker, init fails
with:
/init:500: can't map '/lib/libc.so.0'
/init:500: can't map '/lib/libc.so.0'
/init:500: can't map '/lib/libc.so.0'
/init: can't load library 'libc.so.0'
Kernel panic - not syncing: Attempted to kill init!
This change allows ld.so determine these alignment masks at runtime,
rather than compile-time. Since we have the _dl_pagesize variable
available, we can use that to generate the appropriate masks.
Since almost all of the architectures can use the common definitions for
the _ALIGN macros, we can consolidate them all in ldso.h, and override
in the sysdep headers where necessary (ie, mips).
This allows me to start a uClibc-based root fs on a 64k machine.

This patch will prefix the i and nr_got variable with an underscore to seperate
them from any variables already present in the functions where the macro is
used.
Needed to silence compiler warnings.
