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.

-Subject: fix integer overflow in float printf needed-precision computation
-
-if the requested precision is close to INT_MAX, adding
-LDBL_MANT_DIG/3+8 overflows. in practice the resulting undefined
-behavior manifests as a large negative result, which is then used to
-compute the new end pointer (z) with a wildly out-of-bounds value
-(more overflow, more undefined behavior). the end result is at least
-incorrect output and character count (return value); worse things do
-not seem to happen, but detailed analysis has not been done.
-
-this patch fixes the overflow by performing the intermediate
-computation as unsigned; after division by 9, the final result
-necessarily fits in int.
