Dave Borowitz	a85e817dc2	Rewrite push certificate parsing - 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). This 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.

Rewrite push certificate parsing

- 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).

This 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.
