Problem: missing relicensing statement from bluca

Solution: add it - I realised only now that I only submitted a
statement for the copyright owned by a previous employer, and not
my own.

* Problem: trie benchmarks count loop times instead of lookup calls

Solution: measure the time taken by each lookup call instead

Other changes:
- show average time taken and reduce other output
- show number of keys, queries and key size before running the benchmark
- use steady_clock as high_resolution_clock might not be steady
- increase size of query set to 1M

Use std::condition_variable_any, move configuration to build files

Solution: change into regular control flow condition

Solution: change variable type to size_t

Problem: test_security_curve build fails with Windows targeting 8 or newer due to duplicate definition of htonll

Solution: use custom implementation only on older Windows versions

Solution: move configuration to build definition

Solution: calculate from CMAKE_SYSTEM_VERSION

Problem: CMAKE_SYSTEM_VERSION might be newer than Windows SDK Version

Solution: limit _WIN32_WINNT value to Visual Studio default Windows SDK version

Problem: std::condition_variable can only be used with std::unique_lock<std::mutex>, leading to two mutexes used in condition_variable_t

Solution: use std::condition_variable_any instead

Problem: cannot monitor state of queues at runtime

Solution: add API and ZMQ_EVENT_PIPES_STATS event which generates 2
values, one for the egress and one for the ingress pipes respectively.
Refactor the events code to be able to send multiple values.

Solution: refactor code and add extra frame with value count before the
values in v2

Solution: expect additional events

Solution: update it

Solution: do it, as above 32 bytes they might be on the heap

Solution: check for the available version instead

Solution: add it to doc/Makefile.am

Solution: fix formatting

Solution: remove them for now

Revert 64 bit assertions

This reverts commit ac19d5f4.

This partially reverts commit 19c6aa5c.

Add test for ZMQ_BINDTODEVICE

Solution: return an error to the user instead

Solution: add test case run with cap_net_admin
Fixes #3397

Problem: test build fails on 32 bit systems

Solution: define UNITY_SUPPORT_64 to force 64 bit support

Fix regression introduced by 68d520ef

Solution: run clang-format

Solution: added TODO comment for now

Solution: move unblock call to original location

Solution: make compilation conditional

Solution: add test case

Solution: restore "local" flag values in call to resolve

Fixes #3394

Problem: invoking the conditional variable for zero time is expensive

Add v2 monitoring ipc/tipc tests

Solution: for zero timeout, unlock and relock immediately instead of timedwait

Solution: increase size to 256
