Project structure adjustments

• Regenerated protocol buffer files with Protobuf-C 1.3.0
• Updated layout of folders to separate public, private, and protobuf generated source files
• Update OpenSSL to 1.0.2n
• GCC is now supported in addition to clang

CMake Build System Fixes

Corrected a few CMake issues when using the library as a dependency of another library

New CMake Build System

• The build system has been overhauled to unify the build process as much as possible for all platforms
• Corrected issues building for 64 bit Windows targets
• Added support for 32 bit bcrypt ASM optimizations in the crypt_blowfish package
• Updated Android NDK to a minimum of r14b
• Updated the iOS SDK to a minimum of 9.0

VS 2015 / XCode 9 Support

Added support for Xcode 9 ( iOS 11 / OSX 10.13) and updated from VS 2013 to VS 2015 for Windows

VS 2015 / XCode 9 Support (1.5 backport)

1.5.3

Update openssl make to support iOS 11 SDK builds

Transports

• Packet v4 is now the default for message generation
• Transport Context to support management of Stream Context's in both tx and rx directions, along with key exchanges over a p2p connection. Transports are meant for ephemeral data streams, and will not replace the current messaging protocol for asynchronous text chats
• Support for pre-shared keys as a parameter to a key exchange. This allows for packet decoding to be cryptographically bound to a out-of-band value on top of the existing key exchange mechanism

1.6.0 Beta 2

• Fixed bug where transport data mode did not propagate through copies
• Added missing getter / setter for transport callbacks

OpenSSL 1.0.2l

Made default OpenSSL implementation version 1.0.2l

CMake Bug Fixes

• Force -fPIC flag in protobuf-c to match other sub targets
• Make android NDK location flexible
