libc/arch-arm/bionic/memcpy.a9.S: memcpy from cortex-strings.

This memcpy code uses NEON/VFP to achieve very good performance
on ARMv7-A processors. It is specifically tuned for A15 but should
provide good performance on A9 also. It is equivalent to the code
in cortex-strings rev 116.

This patch is a follow up the existing gerrit change:

I7f6f77995f3ca903ad9c66d14261441667a2a935

But this version includes a tweak for performance on misaligned
buffers.

Update icmp6.h to current NetBSD.

This adds a few bits we need such as RFC 6106 support and the
definition of MLD_LISTENER_REDUCTION.

Fix inttypes.h PRI?PTR and SCN?PTR macros.

Our intptr_t and uintptr_t aren't "long". Add a compilation test so we remember
to fix this to cope with 32- and 64-bit later.

Expose dn_comp and dn_expand to system C code.

This is needed to compile open-source code that wants to
expand/compress domain names itself, such as ping6.
