Like other recursive operations on the dependency graph, this is
not done in a single transaction to prevent an attacker from creating
arbitrary large transactions.
So at startup, the `ValidationManager` finds and resumes any
unfinished operations, by looking for shared messages with unshared
dependencies.
Check whether File#listFiles() returns null
The docs say this can happen if there's an I/O error. Also fixed a throw-in-finally-block warning and renamed an IoUtils method to make its contract clearer.

Add support for comments and reblogging to Blog Client
Comments and reblogs need to depend on the post they refer to.
Since message dependencies are limited to one group,
the post and also the comments need to be wrapped
when commented on or reblogged to another blog (and group).
For this reason, in addition to comments, two new wrapping message types
are introduced. They retain all data of the original messages and allow
for reconstruction and signature verification.
This MR breaks backwards compatibility with old blog posts.
It removes the content type, title and parent ID from the post.
Furthermore, it includes one commit that replaces the `Message` in `MessageSharedEvent` with a `MessageId`.
Closes#494

Before the introducee sends her ACK,
she derives a master key from the ephemeral shared secret as before.
Two nonces and a MAC key are then derived from the master key.
The local introducee signs one of the nonces and calculates a MAC
over her own identity public key, ephemeral public key,
transport properties and timestamp.
The local introducee includes the signature and MAC in her ACK.
On receiving the remote introducee's ACK,
the local introducee verifies the signature and MAC.
Should the verification fail, an ABORT is sent to the introducer and
the remote introducee that was added as inactive is deleted again.

Use Briar's IoUtils.copy(), not H2's IOUtils.copy()
Our implementation closes both streams, H2's implementation leaves them open.
Closes#614.

Blog controller thread safety
This patch removes the mutable list of posts from the blog controller to make it thread-safe, and adds a cache of message bodies to speed up reloads.
Closes#555.

Scrub addresses before logging them
MAC, IP and onion addresses are now scrubbed before logging to ensure we don't leave any sensitive information in plaintext on the device or send it in crash reports or feedback.
* Bluetooth MAC addresses keep the first and last octets
* IPv4 addresses keep the first and last octets
* IPv6 addresses should be scrubbed completely (couldn't test)
* Onion addresses keep the first three characters
If an address is invalid it will not be scrubbed to enable debugging, because it is most likely not sensitive.
Closes#592
