The only symbol that actually needs a prefix to avoid a collision is
_start, and that can be handled with a copy of begin.S that uses a
"#define" to rename _start to __dlwrap__start. Removing the prefixed
symbols will also allow simplifying the host bionic build process by
letting it directly reference the real _start.
Test: build and run host bionic binary

I noticed that sometimes the old unwinder will add an extra PC 0 frame
after this change, but the new unwinder works in all cases. I'm not going
to fix the old unwinder since I plan to remove it very soon.

Test: Forced a crash in the linker and verified that the unwind
Test: stops in __dl_start. Tested on arm/aarch64/x86/x86_64.

There's no need: __linker_init only takes one argument.
Also remove the arm __CTOR_LIST__; we use .init_array and .fini_array instead
of .ctor and .dtor anyway, and I don't think we've ever supported the latter.

Our <machine/asm.h> files were modified from upstream, to the extent
that no architecture was actually using the upstream ENTRY or END macros,
assuming that architecture even had such a macro upstream. This patch moves
everyone to the same macros, with just a few tweaks remaining in the
<machine/asm.h> files, which no one should now use directly.
I've removed most of the unused cruft from the <machine/asm.h> files, though
there's still rather a lot in the mips/mips64 ones.
