Essentially just #645 which fixes compilation on OS X

Fixed memory leak reported in #633

Add -fpermissive plus some other minor things

• Multithreaded building by @novoselrok
• Misc updates of README to link to Ruby bindings and clean up docs
• Better tree splitting, try multiple times ot find more balanced ones
• Fix building on disk and saving large files for Windows
• Misc compilation warnings cleanup

• mostly fixing windows issues with large files
• some error message improvements as well
• doing more stack allocations instead of heap
• fixes to a few tests that were failing on other platforms

Something is busted with version 1.16.1 where I think I must have accidentally uploaded it a long time ago.

Bumping straight to 1.16.2

This is same content as 1.16.1

Mostly minor things to catch user errors and/or explain things better. No functionality change really, except preventing some questionable usage patterns that lead to lots of complexity.

#430 – AVX issues in certain GCC version
#427 – Prevent saving an index that hasn't been built
#425 – Prevent building an index that has already been built
#426 – Handle lseek failures
#419 – ftruncate issues
#410 – swig update
#405 – Use std::sort

The remaining changes were to documentation/test and don't change any functionality

• Fix #379 error handling in save()
• Fix compile issue in linux
• Fix popcount #366
• Some more misc

See #349

Changes:

• #274 – on-disk build
• Fix for xcode: #334
• Minor fix when saving an index to the same file as a current index: #335

• Fixes to the Euclidean distance function (avoid catastrophic cancellation)
• Don't MAP_POPULATE by default

Main (only?) change is that dot products are now supported thanks to @psobot!

Finally squashed a remaining issue with holes (see #295) and together with a few other holes-related fixes it felt worthy of bumping the minor version number.

Fixes #279 and #261

Includes #276

This version features AVX instructions thanks to @ReneHollander

Two big updates

• Windows support now official – with CI pipeline to prove it. Only tested on Python 3.6 so far
• Experimental Hamming distances

• Fixes a problem with holes in the index reported by @yonromai in #223
