Solution: extracted constants

Solution: use UCHAR_MAX constant instead

Solution: calculate from field sizes

Solution: change return type to void, and remove redundant result checks

Solution: extract constants / move to plain_common.hpp

Solution: extract constants and unified cases

Solution: extract constants

Solution: introduced constants

Solution: introduced constants, use std::min/std::max instead of control structures

Solution: use a std::vector instead

Solution: introduced constant

Problem: build broken with clang 6 on Android NDK 17

Solution: ignore tautological-constant-compare warnings, as they
might be useless on 64 bit but they are not on 32 bit where sizeof
size_t != sizeof uint64_t

Solution: fix it

Code style improvements

Solution: apply naming style

Solution: replace by static_cast/reinterpret_cast

Problem: inconsistent naming style for private data members, conflicts with naming of local variables and member functions

Solution: apply and check _lower_case naming style for private data members

Solution: add a comment

Solution: removed

Solution: replace by static_cast, and introduce appropriate constants

Problem: VS2008/2010/2017 tests fail if run in parallel

Solution: run cmake --build --target install instead of msbuild to build on appveyor

Solution: run some builds only on master or *full-ci* branches

Solution: disabled parallel testing for these VS versions

Fix various code style issues

Solution: remove

Solution: remove else

Solution: replace by bool literals

Solution: simplify to comparison against 0

Solution: configured clang-tidy check and applied fixes

Solution: define and apply parameter naming style: lower_case_

Fix ZMQ_HEARTBEAT_TTL maximum value check

Solution: provide definition based on _UI16_MAX

Solution: added tests
