SimilarityRenameDetector: Only attempt to index large files once
If a file fails to index the first time the loop encounters it, the
file is likely to fail to index again on the next row. Rather than
wasting a huge amount of CPU to index it again and fail, remember
which destination files failed to index and skip over them on each
subsequent row.
Because this condition is very unlikely, avoid allocating the BitSet

The counter portion of each pair is only 32 bits wide, but is part
of a larger 64 bit integer. If the file size was larger than 4 GB
the counter could overflow and impact the key, changing the hash,
and later resulting in an incorrect similarity score.
Guard against this overflow condition by capping the count for each
record at 2^32-1. If any record contains more than that many bytes
the table aborts hashing and throws TableFullException.
This permits the index to scan and work on files that exceed 4 GB
in size, but only if the file contains more than one unique block.
The index throws TableFullException on a 4 GB file containing all
zeros, but should succeed on a 6 GB file containing unique lines.
The index now uses a 64 bit accumulator during the common scoring
algorithm, possibly resulting in slower summations. However this
index is already heavily dependent upon 64 bit integer operations
being efficient, so increasing from 32 bits to 64 bits allows us
to correctly handle 6 GB files.

got stuck in an infinite loop as the able couldn't grow, and there

Remove the artifical 2^17 table limit and instead allow the table

Lazy load note subtrees from fanout levels
Instead of reading a note tree recursively up front when the NoteMap
is loaded, read only the root tree and load subtrees on demand when
they are accessed by the application. This gives a lower latency
to read a note for the recent commits on a branch, as only the paths
that are needed get read.
Given a 2/38 style fanout, the tree will fully load when 256 objects
have been accessed by the application. But unlike the prior version
of NoteMap, the NoteMap will load faster and answer lookups sooner,
as the loading time for all 256 levels is spread out across each of
the get() requests.
Given a 2/2/36 style fanout, the tree won't need to fully load until
about 65,536 objects are accessed.
To simplify the implementation we only support the flat layout (all
notes in the top level tree), or a 2/38, 2/2/36, 2/2/2/34, through
2/.../2 style fanout. Unlike C Git we don't support reading the old
experimental 4/36 fanout. This is sufficient because C Git won't
create the 4/36 style fanout when creating or updating a notes tree,
and there really aren't any in the wild today.

Define NoteMap, a simple note tree reader
The NoteMap makes it easy to read a small notes tree as created by
the `git notes` command in C Git. To make the initial implementation
simple a notes tree is read recursively into a map in memory.
This is reasonable if the application will need to access all notes,
or if there are less than 256 notes in the tree, but doesn't behave
well when the number of notes exceeds 256 and the application
doesn't need to access all of them.
We can later add support for lazily loading different subpaths,
thus fixing the large note tree problem described above.
Currently the implementation only supports reading. Writing notes
is more complex because trees need to be expanded or collapsed at
the exact 256 entry cut-off in order to retain the same tree SHA-1
that C Git would use for the same content. It also needs to retain
non-note tree entries such as ".gitignore" or ".gitattribute" files
that might randomly appear within a notes tree. We can also add
writing support later.

element of the inserted region after the LCS was also common but
had fewer occurrences (e.g. 10), while the LCS also contained a
unique element (1 occurrence).
This happens often in Java source code. The initial element for
the LCS might be the empty line ("\n"), and the inserted but common
element might be "\t/**\n", with the LCS being a large span of
lines that contains unique method declarations. Even though "/**"
occurs less often than the empty line its not a better LCS if the
LCS we already have contains a unique element.
The logic in HistogramDiff would normally have worked fine, except I
tried to optimize scanning of B by making tryLongestCommonSequence
return the end of the region when there are matching elements
found in A. This allows us to skip over the current LCS region,
as it has already been examined, but caused us to fail to identify
an element that had a lower occurrence count within the region.
The solution used here is to trade space-for-time by keeping a
table of A positions to their occurrence counts. This allows the
matching logic to always use the smallest count for this region,

extend the Main class and override the lookup.
This is primarily useful when developing new storage implementations
and trying to experiment with the results, without linking all of it
into the core JGit package.

Implemented the initial version of a cherry-pick command.
A correct error handling is missing (what happens if the
checkout fails, the cherry-pick leads to conflicts etc).
But straightforward cherry-picks works.

Add getString utility functions to RawText
These routines can be useful when debugging, because we can add an
expression to the Eclipse "Expressions" panel to show the text that
appears on a line. Gerrit Code Review also uses these in its own
subclass of RawText in order to format patch files, so pulling it up
to be part of core JGit may help other applications too.
