  FS-10198: mod_conference: add var in xml to configure audio recording metadata

FS-10167: Fixed some issues that appeared primarily under windows testing, committing to determine if a specific read access violation occurs under linux as well.

FS-10167: Fixed sessions to cleanup external from their own state processing thread to avoid deadlocking on thread join during cleanup.

FS-10167: Fixed an issue with connection cleanup, the same approach should be taken with sessions to avoid any potential thread deadlock due to cleanup from the same thread which is running the session.

FS-10167: Fixed some issues on library destruction. Added another of the test apps for libblade under windows. Fixed console input under tests.

FS-10167: Fixed bug with ks_pool_resize allocating incorrectly based on recent allocation code changes. Added some missing files as well from prior commits related to libblade test projects and windows VS project property files.

FS-10167: Added windows compilation of libconfig and libsodium to support libblade, all of which now have windows projects and a new libblade solution containing everything. Blade compiles, but many warnings have been disabled and should be reviewed and fixed where reasonable towards clean compiling. Code Analysis has also been enabled for visual studio projects, warnings beginning with C6XXX can be ignored unless adding code-analysis macros to libks and libblade.

FS-10167: Updated libks windows project and test projects to utilize the latest build toolset, and added code analysis to identify potential issues before they occur.

FS-10167: Small fix to the simclist.c assertion guards after having copied the latest from the source git again in the last patch.

FS-10167: Fixed bug in windows test_thread_pools test related to the thread pool itself and ks_q cleanup

FS-10167: Added test_thread_pools to windows build, added BREAK condition to wait for objects to be added to the queue before the workers prematurely exit. Fixed a bug in thread pool creation that wasn't showing up under linux test.

FS-10167: Added testacl to windows build, builds and runs under windows. Added missing testwebsock.vcxproj file that was missing on a prior commit.

FS-10167: Added testwebsock to windows build, completely removed precompiled openssl dependancy and injected the use of core library openssl build, everything seems to build and work for windows thus far.

FS-10167: Removed testmmap as it is no longer relevant, removed windows fake mmap layer which was broken and replaced with direct allocator

FS-10167: Fixed issue with eating processor when ks_sleep() is called on windows, testthreadmutex is now fully functional on windows as well, all tests are passing
