8d8761f248 Make internal symbols hidden. 
Only the malloc/free/... interface is exported.

This allows all of C++'s weak ODR symbols to be resolved at
compile-time, rather than staying weak and resolved at load-time.

Since internal calls don't need to go through the PLT anymore, we get a
nice speedup, at least on small objects.

79b432ddab Fix the condition on when to allocate a new block. 
Previously we would pretty much always allocate a new block for each
allocator, making them 16MiB aligned.

ccd8ec9b4f Disable rtti / exceptions on the non-Windows builds. 
RTTI makes the binaries bigger, exceptions make life harder for
optimisers.  Neither are actually used.

This doesn't preclude anything #including snmalloc.h with RTTI enabled,
it just disables it in the shim libraries and tests.

The FreeBSD libc builds were already doing this with no ill effect.

83c55fe5da Simplify remote allocator. 
Don't store the sizeclass, as we can find it easily, and already are
going to touch though cache lines in the common case.
