Kuan-Wei Chiu ff1a39c3f8 tools/lib/list_sort: remove unnecessary header includes 
Since lib/list_sort.c no longer requires ARRAY_SIZE() and memset(), the
includes for kernel.h, bug.h, and string.h have been removed.  Similarly,
tools/lib/list_sort.c also does not need to include these headers, so they
have been removed as well.

Kuan-Wei Chiu 6d74e1e371 tools/lib/list_sort: remove redundant code for cond_resched handling 
Since cond_resched() is not called in userspace, remove the redundant code
in userspace's list_sort() implementation.  This change eliminates the
unused 'count' variable and the associated logic for invoking cmp()
periodically, which was intended to trigger cond_resched() in kernel
space.

The removed code includes:
- Declaration and increment of the 'count' variable.
- Conditional invocation of cmp() based on 'count'.

This cleanup simplifies merge_final(), avoids unnecessary overhead, and
has no impact on the functionality of list_sort() in userspace.

Ian Rogers 92ec3cc94c tools lib: Adopt list_sort() from the kernel sources 
Add list_sort.[ch] from the main kernel tree. The linux/bug.h #include
is removed due to conflicting definitions. Add check-headers and modify
perf build accordingly.

MANIFEST and python-ext-sources fixes suggested by Arnaldo.
