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.
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.
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.
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.

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.

The release script doesn't need to copy images and css - because that's now done in the jamfiles. Also tweak the shell script a tad bit.
