When a submodule is moved, the "name" field remains the same, while
the "path" field changes. Git uses the "name" field in .git/config
when a submodule is initialized, so this patch makes JGit do so too.

Originally the patterns were escaped twice leading
to wrong matching results.

The intent with the setCompressionLevel and checkExisting methods (which
are already public) is for callers to be able to call them, but they
can't do that if the class itself is not public.

These are ignored by C git when parsing:
$ git config -f - --list <<EOF
[foo "x\0y"]
bar = baz
[foo "x\qy"]
bar = baz
[foo "x\by"]
bar = baz
[foo "x\ny"]
bar = baz
[foo "x\ty"]
bar = baz
EOF
foo.x0y.bar=baz
foo.xqy.bar=baz
foo.xby.bar=baz
foo.xny.bar=baz
foo.xty.bar=baz
This behavior is different from value parsing, where an invalid escape
sequence is an error (which JGit already does as well):
$ git config -f - --list <<EOF
[foo]
bar = x\qy
EOF
fatal: bad config line 2 in standard input

When interleaving reads and writes from an unflushed pack, we forgot to
reset the file pointer back to the end of the file before writing more
new objects. This had at least two unfortunate effects:
* The pack data was potentially corrupt, since we could overwrite
previous portions of the file willy-nilly.
* The CountingOutputStream would report more bytes read than the size
of the file, which stored the wrong PackedObjectInfo, which would
cause EOFs during reading.
We already had a test in PackInserterTest which was supposed to catch
bugs like this, by interleaving reads and writes. Unfortunately, it
didn't catch the bug, since as an implementation detail we always read a
full buffer's worth of data from the file when inflating during
readback. If the size of the file was less than the offset of the object
we were reading back plus one buffer (8192 bytes), we would completely
accidentally end up back in the right place in the file.
So, add another test for this case where we read back a small object
positioned before a large object. Before the fix, this test exhibited
exactly the "Unexpected EOF" error reported at crbug.com/gerrit/7668.

Where the exception being thrown has a constructor that takes a
Throwable, use that instead of instantiating the exception and then
explicitly calling initCause.

In 5e7eed4 a new StoredObjectRepresentationNotAvailableException
constructor was added, that takes a Throwable to initialize the
exception cause.
Update more call sites to use this constructor instead of first
instantiating it and explicitly calling initCause().
All callers now use the new constructor, so annotate the other one as
deprecated.

If the cause can be passed into the constructor, callers don't need to
instantiate it and then explicitly call initCause.
Note that the constructors in this class cause "non-API parameter type"
warnings because ObjectToPack is internal, however it's probably OK
since the only non-internal reference to it is in the pgm.debug package.

Previously, Config was using the same method for both escaping and
parsing subsection names and config values. The goal was presumably code
savings, but unfortunately, these two pieces of the git config format
are simply different.
In git v2.15.1, Documentation/config.txt says the following about
subsection names:
"Subsection names are case sensitive and can contain any characters
except newline (doublequote `"` and backslash can be included by
escaping them as `\"` and `\\`, respectively). Section headers cannot
span multiple lines. Variables may belong directly to a section or to
a given subsection."
And, later in the same documentation section, about values:
"A line that defines a value can be continued to the next line by
ending it with a `\`; the backquote and the end-of-line are stripped.
Leading whitespaces after 'name =', the remainder of the line after
the first comment character '#' or ';', and trailing whitespaces of
the line are discarded unless they are enclosed in double quotes.
Internal whitespaces within the value are retained verbatim.
Inside double quotes, double quote `"` and backslash `\` characters
must be escaped: use `\"` for `"` and `\\` for `\`.
The following escape sequences (beside `\"` and `\\`) are recognized:
`\n` for newline character (NL), `\t` for horizontal tabulation (HT,
TAB) and `\b` for backspace (BS). Other char escape sequences
(including octal escape sequences) are invalid."
The main important differences are that subsection names have a limited
set of supported escape sequences, and do not support newlines at all,
either escaped or unescaped. Arguably, it would be easy to support
escaped newlines, but C git simply does not:
$ git config -f foo.config $'foo.bar\nbaz.quux' value
error: invalid key (newline): foo.bar
baz.quux
I468106ac was an attempt to fix one bug in escapeValue, around leading
whitespace, without having to rewrite the whole escaping/parsing code.
Unfortunately, because escapeValue was used for escaping subsection
names as well, this made it possible to write invalid config files, any
time Config#toText is called with a subsection name with trailing
whitespace, like {foo }.
Rather than pile hacks on top of hacks, fix it for real by largely
rewriting the escaping and parsing code.
In addition to fixing escape sequences, fix (and write tests for) a few
more issues in the old implementation:
* Now that we can properly parse it, always emit newlines as "\n" from
escapeValue, rather than the weird (but still supported) syntax with a
non-quoted trailing literal "\n\" before the newline. In addition to
producing more readable output and matching the behavior of C git,
this makes the escaping code much simpler.
* Disallow '\0' entirely within both subsection names and values, since
due to Unix command line argument conventions it is impossible to pass
such values to "git config".
* Properly preserve intra-value whitespace when parsing, rather than
collapsing it all to a single space.
