PushCertificateParser: Add method for parsing from a stream
We intend to store received push certificates somewhere, like a
particular ref in the repository in question. For reading data back
out, it will be useful to read push certificates (without pkt-line
framing) in a streaming fashion.
Change-Id: I70de313b1ae463407b69505caee63e8f4e057ed4
Discussion on the git mailing list has concluded[1] that the intended
behavior for all (non-sideband) portions of the receive-pack protocol
is for trailing LFs in pkt-lines to be optional. Go back to using
PacketLineIn#readString() everywhere.
For push certificates specifically, we agreed that the payload signed
by the client is always concatenated with LFs even though the client
MAY omit LFs when framing the certificate for the wire. This is still
reflected in the implementation of PushCertificate#toText().

Use local variable in RepositoryTestCase.indexState
There is a signature of the test helper method `indexState`,
in `RepositoryTestCase`, that accepts a `Repository` object
as an argument. However, there was one line of code where
this variable was not being used, and the method was instead
referring to a member variable `db`. I believe this was
probably just an oversight in a previous refactor, and
that the correct behavior is to use the variable from
the argument list. This change also has the benefit
of making it possible to convert this method to a static
method, since it no longer relies on any state from the class.

IllegalArgumentException. Since InvalidObjectIdException is a child of
IllegalArgumentException, callers that catch IllegalArgumentException

Avoid double-colon in InvalidObjectIdException description
The invalidId message in JGitText and the asAscii bad id both contain a

Fix it by keeping the colon in the translated message and not adding

Add a separate type for the identity in a push certificate
These differ subtly from a PersonIdent, because they can contain
anything that is a valid User ID passed to gpg --local-user. Upstream
git push --signed will just take the configuration value from
user.signingkey and pass that verbatim in both --local-user and the
pusher field of the certificate. This does not necessarily contain an
email address, which means the parsing implementation ends up being
substantially different from RawParseUtils.parsePersonIdent.
Nonetheless, we try hard to match PersonIdent behavior in
questionable cases.

a85e817d is a slightly breaking API change to classes that were
technically public and technically released in 4.0. However, it is
highly unlikely that people were actually depending on public behavior,
since there were no public methods to create PushCertificates with
anything other than null field values, or a PushCertificateParser that
did anything other than infinite loop or throw exceptions when reading.

Introduce PostUploadHook to replace UploadPackLogger
UploadPackLogger is incorrectly named--it can be used to trigger any
post upload action, such as GC/compaction. This change introduces
PostUploadHook/PostUploadHookChain to replace
UploadPackLogger/UploadPackLoggerChain and deprecates the latter.
It also introduces PackStatistics as a replacement for
PackWriter.Statistics, since the latter is not public API.
It changes PackWriter to use PackStatistics and reimplements
PackWriter.Statistics to delegate to PackStatistics.

Treat CloneCommand.setBranch(null) as setBranch("HEAD")
This method is documented to take a branch name (not a possibly null
string). The only way a caller could have set null without either
re-setting to a sane value afterward or producing NullPointerException
was to also call setNoCheckout(true), in which case there would have
been no reason to set the branch in the first place.
Make setBranch(null) request the default behavior (remote's default
branch) instead, imitating C git's clone --no-branch.

Treat CloneCommand.setRemote(null) as setRemote("origin")
A non-bare clone command with null remote produces a
NullPointerException when trying to produce a refspec to fetch against.
In a bare repository, a null remote name is accepted by mistake,
producing a configuration with items like 'remote.url' instead of
'remote.<remote>.url'. This was never meant to work.
Instead, let's make setRemote(null) undo any previous setRemote calls
and re-set the remote name to DEFAULT_REMOTE, imitating C git clone's
--no-origin option.
While we're here, add some tests for setRemote working normally.

- Consistently return structured data, such as actual ReceiveCommands,
which is more useful for callers that are doing things other than
verifying the signature, e.g. recording the set of commands.
- Store the certificate version field, as this is required to be part
of the signed payload.
- Add a toText() method to recreate the actual payload for signature
verification. This requires keeping track of the un-chomped command
strings from the original protocol stream.
- Separate the parser from the certificate itself, so the actual
PushCertificate object can be immutable. Make a fair attempt at deep
immutability, but this is not possible with the current mutable
ReceiveCommand structure.
- Use more detailed error messages that don't involve NON-NLS strings.
- Document null return values more thoroughly. Instead of having the
undocumented behavior of throwing NPE from certain methods if they
are not first guarded by enabled(), eliminate enabled() and return
null from those methods.
- Add tests for parsing a push cert from a section of pkt-line stream
using a real live stream captured with Wireshark (which, it should
be noted, uncovered several simply incorrect statements in C git's
Documentation/technical/pack-protocol.txt).

submodule test: Use config.unset instead of setting to null
Most relative-URL tests for SubmoduleInitCommand carry out the following
steps:
1. add a submodule at path "sub" to the index
2. set remote.origin.url in .git/config
3. configure .gitmodules, possibly using relative URLs, and see what
happens
resolveWorkingDirectoryRelativeUrl() is meant to test the fallback when
remote.origin.url is not set, to match C git which treats the URL as
relative to the cwd in that case. To do so, in step (2) it sets
remote.origin.url to null.
However, Config.setString when taking a null value does not actually
unset that value from the configuration --- it sets it to the empty
string. This means we are testing a behavior that C git never
supported. Use Config.unset instead.
