Fix arm64 clone stack handling.
Make sure we adjust the stack pointer so a signal can't overwrite data.

Ensure __set_errno is still visible on LP32.
The use of the .hidden directive to avoid going via the PLT for
__set_errno had the side-effect of actually making __set_errno
hidden (which is odd because assembler directives don't usually
affect symbols defined in a different file --- you can't even
create a weak reference to a symbol that's defined in a different
file).
This change switches the system call stubs over to a new always-hidden
__set_errno_internal and has a visible __set_errno on LP32 just for
binary compatibility with old NDK apps.
(cherry-pick of 7efad83d430f4d824f2aaa75edea5106f6ff8aae.)

Rename __bionic_clone_entry to __start_thread.
This seems a bit less obscure.

Clear link register in __bionic_clone.
Since __bionic_clone uses tail-call to invoke __bionic_clone_entry,
at runtime the unwinder will reach the stack of the clone() function,
which belongs to the parent thread, if the link register is not cleared.

Align the child stack in clone(2).
Also let clone(2) set the TLS for x86.
Also ensure we initialize the TLS before we clone(2) for all architectures.

Align arm64 stacks to 16 bytes in __bionic_clone.
Also ensure that arm64/x86-64/x86 assembler uses local labels.
(There are are so many non-local labels in arm that fixing them
seems out of scope.)
Also synchronize the __bionic_clone.S comments.

Hide the __bionic_clone and __bionic_clone_entry implementation details.
clone(2) is the public symbol.
Also switch a test from __bionic_clone to clone; testing public API
means the test now works on glibc too.
