[guardian-dev] IOCipher v0.3 release: cleaner API and better 5.0/Lollipop/21 support

[Hans-Christoph Steiner]

I just finalized the v0.3 release of IOCipher. This release focused on three
things:

* improved mount error handling
* native binaries that are tested on android-21/5.0/Lollipop
* debug tools for working with encrypted containers on desktop systems

In ChatSecure, we were having issues with an IOCipher store on the SD card.
It seems that users were ejecting the SD card while ChatSecure was running,
then IOCipher's container file was no longer available.  IOCipher's mount()
command made that difficult to troubleshoot, so I changed the API so that
VirtualFileSystem.mount() no longer creates a new file, instead that must
happen by calling VirtualFileSystem.createNewContainer().  This allows mount()
to return much more useful error Exceptions.

The native build was also updated to build with the latest NDK, which should
include fixes related to android-21/5.0/Lollipop.

Lastly, there is now more debug options when working with IOCipher.  It is a
lot easier to mount a IOCipher container file on a desktop system (GNU/Linux)
since ./fuse_sqlfs now accepts the password on stdin.  Additionally, there is
the sqlfsls and sqlfscat utilities for working directly with the IOCipher
container file.
