Partial backport of 07545bc9e3 for Windows, requires building with `--override USE_MEMORY_MIMALLOC=1 --override USE_DELETED_CHAIN=UNDEF` for optimum effect
We don't need the extra precision, in fact it is detrimental to restoring build caches in a cross-platform way.
This commit will invalidate all current build caches.
Cherry-picked from 2a904f3985 (see #1260)
For experimentation only - it's disabled by default unless you also specify --override USE_MEMORY_MIMALLOC=1 (I did not see a discernable benefit over glibc, but more experimentation is warranted, especially with older glibc versions)

Windows' malloc has awful performance. mimalloc is orders of magnitude faster, even faster than DeletedBufferChain. Therefore, only enable USE_DELETED_CHAIN on Windows when building without mimalloc.
On Linux, mimalloc doesn't appear to be measurably faster than glibc's own allocator. Both are marginally than DeletedBufferChain, though, and substantially faster in the multi-threaded case, so USE_DELETED_CHAIN is disabled there in all cases.
Speedup is realised by using thread-local variables. Note that on Windows we can't inline get_current_thread, but it's still faster this way than calling TlsGetValue.
In theory the cache line alignment should help avoid false sharing but I have not profiled that extensively.
* New "Flame Graph" chart for seeing all collectors in a frame, much easier to read than piano roll
* Update controls, fonts, background color to more modern visual style on Windows
* Proper support for high DPI monitors (with correct scaling)
* Add tooltips for collector labels showing full name and averaged value
* Colors of collectors are now converted to sRGB transfer encoding
* Major performance improvement to piano roll view on Windows
* Movering mouse over labels now highlights the corresponding area in chart
* Label hover effect changed to darkening effect instead of border
* Reimplement graph as static common control on Windows
* Check boxes are now clickable by their label on Windows
* Graph windows have minimum sizes on Windows
Useful for uniquely identifying the process in a situation where multiple clients on the same host connect with the same server.
New version bump is not necessary, as old servers should just ignore the extra field in the datagram.
This typedefs to std::atomic<> when building with true threading, and uses a dummy implementation without.
This lets us use the full range of atomic operations offered by C++11, including explicit specification of memory fences. Using barriers lets the compiler generate more optimal code since currently we are using the quite strict sequential-consistent memory ordering for all operations. ReferenceCount has been changed to use the correct barriers (I hope). This may especially make a difference on weak ordering systems such as ARM.
Over time we should gradually replace the use of AtomicAdjust with the new patomic file.
Now behaves consistent with other applications (tested with Logitech MX Master 3 for Mac on macOS 10.13 in unnatural scrolling configuration).
Set `cocoa-invert-wheel-x true` to revert to old behaviour.
This causes an annoying "this app would like to receive keystrokes from any application" alert to be shown
Enable iokit-scan-mouse-devices or iokit-scan-keyboard-devices to restore the old behavior
According to
https://github.com/mayeut/pep600_compliance/blob/master/README.rst
manylinux2010 is EOL, and so are all Linux distributions that support manylinux2010 but not manylinux2014.
Setting the default to manylinux2014 means that more thirdparty packages are supported and hopefully means we're not always behind and have to struggle to keep building for it.
I don't think this flag being missing currently affects any functionality, but it is meant to be set when geometry shaders (with adjacency) are supported.
