* Factor out explicit Config type
Instead of using snmalloc::Alloc::Config, expose snmalloc::Config, which is then used to derive the allocator type.
* Move globalalloc to front end.
* Remove unneed template parameter from global snmalloc functions.
* Remove SNMALLOC_PASS_THROUGH
VeronaRT now has an abstraction layer which can easily replace the allocator.
Having such a complex integration still in snmalloc does not make sense.
* Take some global functions off of local alloc.
* Drop comparison overloads on atomic Capptr.
Performing a comparison on two atomic ptr is a complex operation, and should not be implicit. The memory model order and such things needs to be considered by the caller.
* Remove function_ref and use templates
The implementation prefers to use templates over the function_ref. This now only exists in the Pal for a currently unused feature.
* Removing function_ref reduces stl needs.
* Remove use of __is_convertible to support older g++
* Inline function that is only used once.
* Remove unused function
* Restrict ThreadAlloc usage to globalalloc
This commit introduces various inline functions on snmalloc:: that perform allocation/deallocation using the thread local allocator.
They remove all usage from a particular test.
* Move cheri checks to own file.
* Refactor is_owned checks.
* Move alloc_size and check_size to globalalloc.
* Minor simplification of dealloc path
* Fix up is_owned to take a config
* Improve usage of scoped allocator.
* Handle Config_ in globalalloc.
* Add stress test benchmark

* Add defensive code against spurious wakeup
This commit checks that wait_on_address has not returned spuriously.
* pal: spurious wake up.
The code in the Pal for wake on address was incorrectly assuming the operation returning success meant it had actually changed. The specification allows for spurious wake ups.
This change makes the Pals recheck for a change.

* Handle platforms that have `_GLIBCXX_ASSERTIONS`, which require the stdlib++ to be included.
* Stop override of memcpy with FORTIFY_SOURCE enabled
* Add to .gitignore
* Add data for graphs in release notes.
* Minor tidy on CMake.
The Pagemap can potentially be accessed where there is no direct
knowledge of the location. On platforms with lazy commit this can
be handled by the OS faulting in a zero page. Here we modify the
Windows PAL to add an exception handler that will commit pages
in the read only range, i.e. the page map. We still require explicit
notify_using to be able to modify the pagemap.
When processing a remote batch, the system will process every single message that was available at the start of processing.
This can lead to a long pause time if there have been a considerable number of frees to this thread.
This commit introduces a new mechanism to only process messages up to a limit of 1MiB. The limit is configurable using CMake.
Choosing too small a limit can cause freeing to never catch up with the incoming messages.
