Florian Weimer cff2c78c51 resolv: Move ns_name_skip to its own file and into libc (bug 28091)
And reformat to GNU style.  Avoid out-of-bounds pointer arithmetic.
This also results in a fix of bug 28091 due to the additional packet
length checks.

The symbol was moved using scripts/move-symbol-to-libc.py.

Florian Weimer adcc572a29 resolv: Move ns_name_ntop to its own file and into libc
Reformat to GNU style.  Avoid out-of-bounds pointer arithmetic
(e.g., use eom - dn < 2 instead of dn + 1 >= eom).  Inline the
labellen function and fold the compression pointer check into
the length check (l >= 64).  Assume ASCII encoding.

Adhemerval Zanella 605f38177d sh: Split BE/LE abilist
The fix for BZ#18231 requires new symbols only for sh4eb.  This patch
adds the required folder and files for both BE and LE abilist.  No
semantic changes are expected.

Checked with check-abi for sh4eb-linux-gnu and sh4-linux-gnu.
