musl: update musl to 1.1.16+ and switch to download from git
This patch updates musl to 1.1.16+ [0] and removes all the
backported patches. This is a major release and tagged as such.
For more information visit musl-libc.org or read the WHATSNEW.
Furthermore, this patch also changes musl to download directly
from git. This makes it easier to update musl in the future.
The patch custom Add-format-attribute-to-some-function-declarations.patch
was assigned a new 400- number. This should avoid confusion
since 0xx numbers are usually assigned to backports.
