bswap: fix compiler warning

The bswap functions use memcpy but the bswap.h header itself does not seem to
include it in some configuration such as cross compiling for powerpc64
on x86_64 machine.

The patch explicitly includes string.h.

bswap: Fix width of swap in leul_to_cpu

The misnamed HOST_LONG_BITS is really HOST_POINTER_BITS. Here we're
explicitly using an unsigned long, rather than uintptr_t, so it is
more correct to select the swap size via ULONG_MAX.

bswap: improve gluing

OpenBSD system compiler (gcc 4.2.1) has problems with concatenation
of macro arguments in macro functions:

bswap: Rewrite cpu_to_<endian><type>u with {ld,st}<type>_<endian>_p

We've now optimized the ld/st versions; reuse that for the "legacy"
versions. Always use inlines so that we get the type checking that
we expect.

bswap: Rewrite all ld<type>_<endian>_p functions

Use the new host endian unaligned access functions instead of
open coding byte-by-byte references. Remove assembly special
cases for i386 and ppc -- we've now exposed the operation to
the compiler sufficiently for these to be optimized automatically....

bswap: Tidy base definitions of bswapN

Move the bswap_N -> bswapN wrappers inside CONFIG_BYTESWAP_H.

Change the ultimate fallback defintions from macros to inline functions.
The proper types recieved by the function arguments means we can remove
unnecessary casts, making the code more readable....
