All patches gone upstream.  Changes from 0.3.6 to 0.3.7 are basically
all those patches plus some build warnings removed and typos fixed.

-Subject: [PATCH] Make libyaml optional
-
-NewYAML format is required for extended features because the format
-foreseen by U-Boot is very limited. However, some systems due to
-low resources don't want to link to libyaml. Add the option
-NO_YML_SUPPORT to disable YAML configuration file and just use
-fw_env.config in the U-Boot format.
-
-There are no functional changes in this patch - function depending on
-YML are moved in a separate file, and some functions are factorized.

-Subject: [PATCH] libubootenv: fix segfault due to uninitialized pointer in
- config parser
-
-Issue: The issue was introduced in commit c478e8d9, which replaced the use of %ms in sscanf() with a calloc()-based workaround for platforms where %ms is not supported (e.g., FreeBSD).
-However, this change inadvertently introduced a logic flaw: it uses calloc to emulate %ms% in sscanf() but also added 2 free instructions which could lead to free non-allocated memory on tmp when sscanf()
-is used to perform the dynamic allocation.
-
-Fix: Ensure `tmp` is initialized to NULL before each call to sscanf with `%ms`
-in `libuboot_read_config_ext()`. This prevents `free(tmp)` from crashing
-when sscanf fails to allocate memory (e.g., due to malformed config lines).
-
-Fixes segmentation fault observed when running swupdate with a ubootenv config file.

> -Issue: The issue was introduced in commit c478e8d9, which replaced the use of %ms in sscanf() with a calloc()-based workaround for platforms where %ms is not supported (e.g., FreeBSD).
> -However, this change inadvertently introduced a logic flaw: it uses calloc to emulate %ms% in sscanf() but also added 2 free instructions which could lead to free non-allocated memory on tmp when sscanf()
> -is used to perform the dynamic allocation.
> -
> -Fix: Ensure `tmp` is initialized to NULL before each call to sscanf with `%ms`
> -in `libuboot_read_config_ext()`. This prevents `free(tmp)` from crashing
> -when sscanf fails to allocate memory (e.g., due to malformed config lines).
> -
> -Fixes segmentation fault observed when running swupdate with a ubootenv config file.
