Otherwise libc_malloc_debug_leak.so is failed to load runtime in x86
case

To properly support legacy ARM shared libraries, libc.so needs
to export the symbols __dso_handle and atexit, even though
these are now supplied by the crt startup code.
This patch reshuffles the existing CRT_LEGACY_WORKAROUND
conditionally compiled code slightly so it works as the
original author likely intended.

Useful if you're trying to defeat ASLR, otherwise not
so much ...

Move dlmalloc code to upstream-dlmalloc to make pulling upstream changes
easier.
Declare pvalloc and malloc_usable_size routines present in malloc.h but with
missing implementations. Remove other functions from malloc.h that have
no implementation nor use in Android.

Add __bionic_clone function for x86, which will be
used for clone system call.

This should help prevent broken builds next time I'm messing with
assembler/compiler/linker flags...

This reverts commit 8793e7c7d21a0434d1b5e63364c88b2b125a3d29,
and fixes the build by building upstream NetBSD source as a
separate library that's then swallowed whole into libc_common.

There were two bugs in our implementation. Intel found one, but another
remainined, and tracking upstream is the way forward for functions where
we add no value.

This allows debugging tools to know they are working with Android
binaries and adapt accordingly.

This test is designed to detect code such as:
int main() {
char buf[10];
memcpy(buf, "1234567890", sizeof(buf));
size_t len = strlen(buf); // segfault here with _FORTIFY_SOURCE
printf("%d\n", len);
return 0;
}
or anytime strlen reads beyond an object boundary. This should
help address memory leakage vulnerabilities and make other
unrelated vulnerabilities harder to exploit.

libc's stack protector initialization routine (__guard_setup)
is in bionic/ssp.c. This code deliberately modifies the stack
canary. This code should never be compiled with -fstack-protector-all
otherwise it will crash (mismatched canary value).
Force bionic/ssp.c to be compiled with -fno-stack-protector
