FS-10225: [mod_conference] Incorrect layout chosen when playing a file in a conference with a layout group Don't change layout when playing full-screen anyway

FS-10225: [mod_conference] Incorrect layout chosen when playing a file in a conference with a layout group #resolve

FS-10167: Rewrote the ks_pool allocator, no longer uses paging or internal block allocation, but still retains reference counting and auto cleanup callbacks, should be much more efficient now on windows than the original mmap approach, and all tests now run successfully!

FS-10222: [freeswitch-core] add disable_audio_jb_during_passthru and disable_video_jb_during_passthru  #resolve

FS-10167: Committing for a clean revert point prior to work on ks_pool internal allocator issues that were identified as the cause of the complicated bug related to freeing pages introduced by switching to malloc/free.

Merge pull request #1245 in FS/freeswitch from ~DRAGOS_OANCEA_NX/freeswitch-dragos-nx:feature/FS-10198/conf_recording_metadata to master

  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.
