[GIT PULL V3] JNI bindings for libopenconnect; other fixes

[Kevin Cernekee]

Here is the latest iteration of my JNI/Android patch series.


V2->V3 changes:

Add protect_socket callback to allow binding VPN connection sockets to
a non-VPNed interface

Specify reconnect_{timeout,interval} in openconnect_mainloop() arguments

Use select() to sleep during reconnect, to remain responsive to aborts
via cancel_fd

Improve error handling in JNI init() function

Make a few of the Java callbacks optional

Add "android" and "ios" OS types + CSD support

Fixes for a couple of miscellaneous problems reported on the list


This passes CheckJNI, and there is a somewhat-functional ICS+ Android
app posted at:
