Currently, our getaddrinfo implementation does not conform to
any IETF standard. It follows draft-ietf-6man-rfc3484-revise-01,
but that draft has expired. Update the policy table to RFC6724.

This uses the new code original submitted as memcpy.a15.S as
the base. However, the old code handled unaligned src/dst better
so that was spliced in. I optimized the original unaligned code by
removing a few unnecessary instructions. I optimized the a15 code by
rewriting the pre and post code. I also modified the main loop to add
a pld so that larger copies would not stall waiting for memory.
Test cases for the new memcpy:
- Copy all sized values from 0 to 1024 bytes, using whatever alignment
is returned by malloc.
For each alignment case described below, the test copied from 0 to 128
bytes.
- Src and dst pointers are both aligned to the same value, starting
at one going through every power of two up to and including 128.
- Src aligned to double word boundary, dst aligned to word boundary.
- Src aligned to word boundary, dst aligned to double word boundary.
- Src aligned to 16 bit boundary, dst aligned to word boundary.
- Src aligned to word boundary, dst aligned to 16 byte boundary.
- Src aligned to word boundary, dst aligned to 1 byte from a word
boundary.
- Src aligned to word boundary, dst aligned to 2 bytes from a word
boundary.
- Src aligned to word boundary, dst aligned to 3 bytes from a word
boundary.
- Src aligned to 1 byte from a word boundary, dst aligned to a word
boundary.
- Src aligned to 2 bytes from a word boundary, dst aligned to a word
boundary.
- Src aligned to 3 bytes from a word boundary, dst aligned to a word
boundary.
Cases to verify the unaligned source code properly aligns to a 16 bit
boundary.
- Src aligned to 1 byte from a 128 bit boundary, dst aligned to
4 + 128 bit boundary.
- Src aligned to 1 byte from a 128 bit boundary, dst aligned to
8 + 128 bit boundary.
- Src aligned to 1 byte from a 128 bit boundary, dst aligned to
12 + 128 bit boundary.
- Src aligned to 1 byte from a 128 bit boundary, dst aligned to
16 + 128 bit boundary.
In all cases, a two byte fencepost was placed at the end of the
destination to verify that only the requested number of bytes were copied.

pthread_create returns EAGAIN when it can't allocate a pthread_internal_t,
when it can't allocate a stack for the new thread, or when clone(2) fails
because there are too many threads. It's useful to be able to know why your
pthread_create just failed, so add some logging.

Need to get the defintion of the FITRIM ioctl(). Also need
to update the blk_types.h header file as fs.h includes it.
