Sara Dickinson 3de15ad782 Change internal transport handling to use a list, not a fixed type 2015-04-24 16:29:08 +01:00
Sara Dickinson f2ae55858f First pass at making handshake async. Lots of issues with this code still 
- timeouts are not being rescheduled on fallback
- several error cases are not being handled correctly (e.g. 8.8.8.8) and a user callback is not always called
- the fallback mechanism is not generic (specific to tls to tcp)

Sara Dickinson 6c7ffc4e4e 1) Fix enum mapping error. 
2) Also add detection of TLS 1.2 in openssl during configure and warn that it if not available then TLS will not be available. Using TLS_ONLY in stub mode will then error with BAD_CONTEXT. TLS/TCP will fallback to TCP.

3) Explicitly disallow use of TLS_ONLY in RECURSIVE mode since it isn't supported yet. TLS/TCP will fallback to TCP.

4) Fix for MAC OS X build where openssl not linked correctly

Sara Dickinson ab4fb8d9e9 Enable GETDNS_TRANSPORT_TLS_ONLY_KEEP_CONNECTIONS_OPEN for libunbound. Should only be used in stub mode. 
GETDNS_TRANSPORT_TLS_FIRST_AND_FALL_BACK_TO_TCP_KEEP_CONNECTIONS_OPEN still just does TCP.
Also some tidy up of new transport types.

Willem Toorop 4a3d7fd8b2 Replace ldns_rbtree with getdns_rbtree 
As much as possible.
In dnssec ldns_rbtree is inderectly used via the dnssec_zone struct

This change forces use to embed the data in the nodes as getdns_rbtree does not have a data attribute. This is good because lesser allocs and free's and thus slightly faster and less likely to leak memory.

So async and sync functions now have the same code path
