Add upstream patch fixing CVE-2017-14062:
Integer overflow in the decode_digit function in puny_decode.c in
Libidn2 before 2.0.4 allows remote attackers to cause a denial of
service or possibly have unspecified other impact.
This issue also affects libidn.
Unfortunately, the patch also triggers reconf of the documentation
subdirectory, since lib/punycode.c is listed in GDOC_SRC that is defined
in doc/Makefile.am. Add autoreconf to handle that.
