Subject: [PATCH 1/3] Use AC_USE_SYSTEM_EXTENSIONS
Instead of using #define _GNU_SOURCE in some source files which causes problems
when building with musl as more files need the define, simply use
AC_USE_SYSTEM_EXTENSIONS in configure.ac to get it defined globally.

Subject: [PATCH 2/3] Check for in6_pktinfo.ipi6_addr explicitly
Instead of assuming that just glibc has this structure, check for it at
configure as musl also has it.

Subject: [PATCH 3/3] Rationalise includes
gweb/gresolv.c uses snprintf() and isspace() so it should include stdio.h and
ctype.h.
tools/dnsproxy-test uses functions from stdio.h.
musl warns when sys/ headers are included when the non-sys form should be used,
so switch sys/errno.h and so on to errno.h.
musl also causes redefinition errors when pieces of the networking headers are
included, so remove the redundant includes.
Based on work by Khem Raj <raj.khem@gmail.com>.
