fix tmux crashing bug (#6766) 
Co-authored-by: Henry Beberman <henry.beberman@microsoft.com>

Fixes issue #6598 which is a crash on selection in tmux. The fix requires an update to ncurses and a patch to tmux. From the patch comments:

```
ncurses-6.4-20230408 change tparm to require cur_term, which broke tmux usage of it.

ncurses-6.4-20230423 then added tiparm_s that allows usage without cur_term.

tmux change 39d41d0810 uses tiparm_s if it exists, but cannot be cleanly applied to tmux tag 3.2a.

That change uses a config setting to created #defines to determine which version of tparm it should use, and only conditionally uses tiparm_s, because it needs to be backwards compatible with previous versions of ncurses.

But to use that, we would need to get the actual source as it appears in github, rather than the released version (they are different downloads: see https://github.com/tmux/tmux/releases).

Fortunately, we have the luxery of forcing tmux to use a version of ncurses that has the function we want (see above).

Given all this, this patch takes the change to use tiparm_s, removes the conditional compilation portion so it always uses tiparm_s and applies it to the code as it exists in 3.2a.

It has both a build-time and run-time dependency on ncurses-6.4-20230423 or later.

CBL-Mariner

CBL-Mariner is an internal Linux distribution for Microsoft’s cloud infrastructure and edge products and services. CBL-Mariner is designed to provide a consistent platform for these devices and services and will enhance Microsoft’s ability to stay current on Linux updates. This initiative is part of Microsoft’s increasing investment in a wide range of Linux technologies, such as SONiC and Windows Subsystem for Linux (WSL). CBL-Mariner is being shared publicly as part of Microsoft’s commitment to Open Source and to contribute back to the Linux community. CBL-Mariner does not change our approach or commitment to any existing third-party Linux distribution offerings.

CBL-Mariner has been engineered with the notion that a small common core set of packages can address the universal needs of first party cloud and edge services while allowing individual teams to layer additional packages on top of the common core to produce images for their workloads. This is made possible by a simple build system that enables:

  • Package Generation: This produces the desired set of RPM packages from SPEC files and source files.
  • Image Generation: This produces the desired image artifacts like ISOs or VHDs from a given set of packages.

Whether deployed as a container or a container host, CBL-Mariner consumes limited disk and memory resources. The lightweight characteristics of CBL-Mariner also provides faster boot times and a minimal attack surface. By focusing the features in the core image to just what is needed for our internal cloud customers there are fewer services to load, and fewer attack vectors.

When security vulnerabilities arise, CBL-Mariner supports both a package-based update model and an image based update model. Leveraging the common RPM Package Manager system, CBL-Mariner makes the latest security patches and fixes available for download with the goal of fast turn-around times.

Getting Started with CBL-Mariner
