[GIT PULL V2] Fixes for rekeying, Android builds, etc.

[Kevin Cernekee]

V1->V2:

 - Added reference to Android local symbol relocation issue:
   https://code.google.com/p/android/issues/detail?id=66048

 - Added minor AC_CONFIG_FILES fix

 - Rebase on latest upstream master

You guys might want to hold off on "Rework DTLS master secret
(re)generation" depending on what Nikos' rekeying changes wind up looking
like?  The most critical fix in my commit is making sure that DTLS
re-handshakes after sending a new DTLS master key to the gateway.  This
is currently a major problem on mobile since the device is constantly
disconnecting and reconnecting due to suspend/resume and network
connectivity changes.  Without the fix, the client's DTLS parameters
eventually get out of sync with the server's parameters, and no data
traffic can pass.



The following changes since commit 18e0f494d1b8e571be2cf535a3fa067db894034e:
