4a4cb9f7a4 Use is_zero workaround on clang 
The same warning appears on clang for windows, but the workaround wasn't
used because the gcc macro wasn't defined.

d0ee8e13bd Support for removed function objects in C++17 
std::unary_function and std::binary_function are removed in C++17, and
Visual C++ is the first compiler to do this (when the appropriate macro
is defined). I'm not sure what the long term solution should be, but
hopefully this will work for now.

754d5f535e Fixed strict aliasing violation. 
Changed C-style cast and dereference to std::memcpy.  Exactly mirrors other code already in the file.

309d17f387 Another try at an improved hash function. 
This is based on the mix function from MurmurHash. It's not the full
algorithm as it's always seeded with 0, and doesn't do a final mix. This
should be okay as Boost.Hash doesn't claim to avalanche the bits.

bb2a91bf47 Improved(?) hash function. 
Given the existing interface, it's quite tricky to use most popular hash
functions without a change, so I'm using a modified version of FNV1a.
The current function always starts with a seed of 0 (and will in user
functions), so I'm adding the offset each time instead. I'm not sure if
that will work as well.

dea8d12a04 Fix Visual C++ warning in hash. Refs #8568. 
I changed this a little from the patch on #8568. I moved the pragmas to the
start and end of the file because I don't like to little the body of the code
with them (this does mean I've disabled a potentially useful warning, but the
code is pretty stable nowadays).

I also removed the version checks, as the warning should be present in later
versions.

8a8ab9ec70 Hash: Fix int128 with BOOST_HASH_NO_EXTENSIONS. 
I don't think int128 should count as an extension.

BOOST_HASH_NO_EXTENSIONS is actually a bit of a pain, and I don't think it's
that useful. Maybe I should deprecate it.

9119b2646b Hash: Remove C++11 forward declarations. 
It seems that on Visual C++ Dinkumware declares shared_ptr in std, but for
Intel C++ it imports it from std::tr1. I was thinking of doing a macro check
for this, but since we're close to release, just change it to always include
the headers and never forward declare the C++11 classes, which is much safer.

I might restore the forward declarations in the future, although I'm tempted
not to. I'm not sure the improvement in compile time is worth the hassle.
