wireprotov2: define and implement "filedata" command
Continuing our trend of implementing *data commands for retrieving
information about specific repository data primitives, this commit
implements a command for retrieving data about an individual tracked
file.
The command is very similar to "manifestdata." The only significant
difference is that we have a standalone function for obtaining
storage for a tracked file. This is to provide a monkeypatch point
for extensions to implement path-based access control.
With this API available, wire protocol version 2 now exposes all
data primitives necessary to implement a full clone. Of course,
since "filedata" can only resolve data for a single path at a time,
clients would need to issue N commands to perform a full clone. On
the Firefox repository, this would be ~461k commands. We'll likely
need to implement a file data retrieval command that supports
multiple paths. But that can be implemented later.

+filedata
+--------
+
+Obtain various data related to an individual tracked file.
+
+The command accepts the following arguments:
+
+fields
+ (set of bytestring) Which data associated with a file to fetch.
+ The following values are recognized:
+
+ parents
+ Parent nodes for the revision.
+
+ revision
+ The raw revision data for a file.
+
+nodes
+ (array of bytestrings) File nodes whose data to retrieve.
+
+path
+ (bytestring) Path of the tracked file whose data to retrieve.
+
+TODO allow specifying revisions via alternate means (such as from
+changeset revisions or ranges)
+
+The response bytestream starts with a CBOR map describing the data that
+follows. It has the following bytestream keys:
+
+totalitems
+ (unsigned integer) Total number of file revisions whose data is
+ being returned.
+
+Following the header map is a series of 0 or more CBOR values. The first
+value is always a map describing a file revision. If this map has the
+``deltasize`` or ``revisionsize`` keys, a bytestring containing the delta
+or revision, respectively, will immediately follow the map. Otherwise
+the next value will be a map describing the next file revision.
+
+Each map has the following bytestring keys:
+
+node
+ (bytestring) The node of the file revision whose data is represented.
+
+deltabasenode
+ (bytestring) Node of the file revision the following delta is against.
+
+ Only present if the ``revision`` field is requested and delta data
+ follows this map.
+
+deltasize
+ (unsigned integer) The size of the delta data that follows this map.
+
+ Only present if the ``revision`` field is requested and delta data
+ follows this map.
+
+parents
+ (array of bytestring) The nodes of the parents of this file revision.
+
+ Only present if the ``parents`` field is requested.
+
+revisionsize
+ (unsigned integer) The size of the fulltext revision data that follows
+ this map.
+
+ Only present if the ``revision`` field is requested and fulltext revision
+ data follows this map.
+
+When ``revision`` data is requested, the server chooses to emit either fulltext
+revision data or a delta. What the server decides can be inferred by looking
+for the presence of the ``deltasize`` or ``revisionsize`` keys in the map.
+Servers MUST NOT define both keys.
