wireproto: use new peer interface
The wirepeer class provides concrete implementations of peer interface
methods for calling wire protocol commands. It makes sense for this
class to inherit from the peer abstract base class. So we change
that.
Since httppeer and sshpeer have already been converted to the new
interface, peerrepository is no longer adding any value. So it has
been removed. httppeer and sshpeer have been updated to reflect the
loss of peerrepository and the inheritance of the abstract base
class in wirepeer.
The code changes in wirepeer are reordering of methods to group
by interface.
Some Python code in tests was updated to reflect changed APIs.
.. api::
peer.peerrepository has been removed. Use repository.peer abstract
base class to represent a peer repository.

2 files. |
| 14686 | 3 |
| 4 Like other file patterns, this pattern type is indicated by a prefix, | |
| 5 'set:'. The language supports a number of predicates which are joined | |
| 6 by infix operators. Parenthesis can be used for grouping. | |
| 7 | |
| 8 Identifiers such as filenames or patterns must be quoted with single | |
| 9 or double quotes if they contain characters outside of | |
| 10 ``[.*{}[]?/\_a-zA-Z0-9\x80-\xff]`` or if they match one of the | |
| 11 predefined predicates. This generally applies to file patterns other | |
| 12 than globs and arguments for predicates. | |
| 13 | |
| 14 Special characters can be used in quoted identifiers by escaping them, | |
| 15 e.g., ``\n`` is interpreted as a newline. To prevent them from being | |
| 16 interpreted, strings can be prefixed with ``r``, e.g. ``r'...'``. | |

| 14686 | 23 There is a single prefix operator: |
| 24 | |
| 25 ``not x`` | |
| 26 Files not in x. Short form is ``! x``. | |
| 27 | |
| 28 These are the supported infix operators: | |
| 29 | |
| 30 ``x and y`` | |
| 31 The intersection of files in x and y. Short form is ``x & y``. | |
| 32 | |
| 33 ``x or y`` | |
| 34 The union of files in x and y. There are two alternative short | |
| 35 forms: ``x | y`` and ``x + y``. | |
| 36 | |
| 37 ``x - y`` | |
| 38 Files in x but not in y. | |
