In different places (Main, TextBuiltin, CLIGitCommand) we report fatal
errors and at same time want to check for fatal errors in the tests.
Using common API simplifies the error testing and helps to navigate to
the actual error check implementation.

Make sure tests don't blindly continue if a command is "silently" failed
Make the default execute() function fail fast on first command printed
"fatal: " to output.
Introduced executeUnchecked() for few tests which wanted to test fatal
output.

Make recursive merge strategy the default merge strategy
Use recursive merge as the default strategy since it can successfully
merge more cases than the resolve strategy can. This is also the default
in native Git.

jgit.storage.dht is a storage provider implementation for JGit that
permits storing the Git repository in a distributed hashtable, NoSQL
system, or other database. The actual underlying storage system is
undefined, and can be plugged in by implementing 7 small interfaces:
* Database
* RepositoryIndexTable
* RepositoryTable
* RefTable
* ChunkTable
* ObjectIndexTable
* WriteBuffer
The storage provider interface tries to assume very little about the
underlying storage system, and requires only three key features:
* key -> value lookup (a hashtable is suitable)
* atomic updates on single rows
* asynchronous operations (Java's ExecutorService is easy to use)
Most NoSQL database products offer all 3 of these features in their
clients, and so does any decent network based cache system like the
open source memcache product. Relying only on key equality for data
retrevial makes it simple for the storage engine to distribute across
multiple machines. Traditional SQL systems could also be used with a
JDBC based spi implementation.
Before submitting this change I have implemented six storage systems
for the spi layer:
* Apache HBase[1]
* Apache Cassandra[2]
* Google Bigtable[3]
* an in-memory implementation for unit testing
* a JDBC implementation for SQL
* a generic cache provider that can ride on top of memcache
All six systems came in with an spi layer around 1000 lines of code to
implement the above 7 interfaces. This is a huge reduction in size
compared to prior attempts to implement a new JGit storage layer. As
this package shows, a complete JGit storage implementation is more
than 17,000 lines of fairly complex code.
A simple cache is provided in storage.dht.spi.cache. Implementers can
use CacheDatabase to wrap any other type of Database and perform fast
reads against a network based cache service, such as the open source
memcached[4]. An implementation of CacheService must be provided to
glue this spi onto the network cache.

Per CQ 3448 this is the initial contribution of the JGit project
to eclipse.org. It is derived from the historical JGit repository
at commit 3a2dd9921c.
