FS-10167: Switched connection lifecycle to an isolated pool similar to sessions, also refactored the inner WSS transport implementation to be part of the same pool so it is cleaned up with the connection. Switched the connection state machine thread to also utilize thread pool to avoid direct ownership over the thread, similar to session but without the use of a signaled condition due to abstraction of transports which may need to deal with polling for socket events such as with WSS transport. Completely removed the temporary worker thread in the main handle that was for connection/session cleanup.

FS-10225: [mod_conference] Incorrect layout chosen when playing a file in a conference with a layout group -- revert small piece

FS-10167: Added ks_list_delete_iterator() to delete the node at the current iterator position (only if available if iterator is active). Updated blade_session to reflect ks_list_t being internally thread-safe now.

FS-10233: [mod_local_stream] mod_local_stream segfault trying to read a music file that is not open while playing a chime #resolve

FS-10167: Refactored simclist for ks-ification, and adjusted it for pool-based allocations and cleanup

FS-10225: [mod_conference] Incorrect layout chosen when playing a file in a conference with a layout group -- Edge case with file-only slots

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.
