ebfe22bfb9 fs: rename PSEUDOFS_SOFTLINKS to FS_LINKS 
The link support is no longer limited to the pseudo file system and now
covers both soft (symbolic) links and hard links across the VFS.  Rename
the configuration option PSEUDOFS_SOFTLINKS to the more accurate FS_LINKS
and update all references in the source, headers, Kconfig, documentation
and board defconfigs accordingly.

This is a configuration rename; any out-of-tree defconfig that still
selects PSEUDOFS_SOFTLINKS must be updated to FS_LINKS.

1cb1fb427d libc: Replace all malloc/free to lib_malloc/lib_free 
since libc can be built and used in kernel space,
we must call kmm_malloc and kmm_free in this case.
