72cf2d4f0e Fix sys-queue.h conflict for good 
Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc923584,
f40d753718,
96555a96d7 and
3990d09adf but the fixes were fragile.

Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.

ec822001a2 Fix symfind. 
this patch fixes an issue in symfind.

Assume you have the following symbols:

Address  Size
0045bca0 00000080 T s0
0045bd20 00000112 T s1

You'll notice that s1 is s0 + size.

So the current symfind will find that address 0045bd20 belongs to s0
instead of s1.

9fdca5aa5d Use correct byteswap routine for elf_note 
All elf64_note structure members are Elf64_Word (which is 32bit value)
hence using bswaptls to byteswap it on 64bit platforms is incorrect.

edf8e2af14 linux-user: implemented ELF coredump support for ARM target

though).

e58ffeb322 Remove all traces of __powerpc__ 
According to $GCC/gcc/config/rs6000/rs6000-c.c _ARCH_PPC is the
ubiquitous define which should be used to test whether gcc targets
PowerPC, on 64bit platforms _ARCH_PPC64 will be also defined.

49918a752b * Use function pointers for symbol lookup (currently for elf32 and elf64, 
could be expanded).  This also fixes the bug with mips elf64 symbols
  in current Qemu trunk.

* Use quicksort and binary search for symbol lookup.

* Remove unneeded entries from symbol table.  This reduced a typical table
  size (linux mips kernel) from 1764487 to 11656 entries.

a6cc84f49c Kludge to support linux-user on a PPC64 
Some headers (e.g. signal.h) include asm/elf.h and the chaos of macro
redefinitions ensues, this kludge avoids it.

Alternative way to fight that would be to change all ELF_XXX and some
other definitions to QEMU_ELF_XXX or something to that effect.

This patch concludes the quest for enabling linux-user on PPC64,
however, since qemu_mallocz uses mmap and, at least on this system,
mmap tends to return values that do not fit into 32bit, emulation for
32bit targets does not work without some hacks wich are to disgusting
to commit (and as `man mmap' tells us MAP_32BIT is only implemented on
X86_64)
