0652302d9a Common/MemoryTracker: fix metrics not being updated after MemoryTracker reset 
The #3230 fixed a problem with memory accounting, but it introduces a regression
in which the memory tracker isn't reset until there are zero queries in process list.
This makes it difficult to see in tests as there's always just one query in-flight,
but in production it produces a sawtooth memory usage pattern that resets when
the allocated memory exceeds set memory limits and all queries are terminated.

fb1aa84973 Fixed clang build on macOS 
- Make sure to use dynamic linking on macOS to avoid OpenSSL static linking bug
- Use -std=c++17 in CFLAGS for files in contrib
- Avoid bad support for thread_local on macOS with clang altogether

ba82b20cbe MemoryTracker: fixed build with clang 9.0.0 not properly supporting thread_local 
This fixes #1488.

XCode 9.0 added support for C++11 thread_local:
https://developer.apple.com/library/content/releasenotes/DeveloperTools/RN-Xcode/Chapters/Introduction.html

The 443088ce31 replaced __thread with C++11 thread_local, which
broke the compilation for this platform with an error on link time.

I can't reproduce this with a minimal example yet.
