Fix IPv4 address in replies to A or NS queries (github issue #38 )
...
The destination field in struct query was changed from in_addr_t to
struct sockaddr_storage, wihtout updating the functions sending it
in src/dns.c.
Only add extra A answer for NS queries if destination refers to an
IPv4 address, and fail if trying to encode a reply to an A query
if destination is not IPv4.
This means NS requests received over IPv6 will not contain an address
and A requests will be ignored, unless the -n option is used, or the
www subdomain is requested which sets a fixed address (127.0.0.1).

Add support for Android L
...
Build position-indepent executables, required for Android L (5.0+)
They also work with kitkat.
Add new maketarget "cross-android-old" that builds without PIE
for older versions.
Include both new and old versions in latest-android.zip. Add arm64.
Hopefully solves github PR #14 .

Add support for using an unspecified RR type
...
Add PRIVATE query type with id 65399 (private use range).
According to RFC3597 the reply data in a query with unspecified RR type must be handled
as unstructured binary data, which means it can contain raw packet data just like the NULL type.
Since the reply format is optimal it is ordered just after NULL in the priority order.

rewrite comparison to avoid negative unsigned numbers
...
Note that GCC -O2 is happy to optimize away (x<0) when x is an
unsigned quantity. This was actually occurring in CHECKLEN(0),
causing the compiler to issue a warning.
