wireprotov2: change how revisions are specified to changesetdata
Right now, we have a handful of arguments for specifying the revisions
whose data should be returned. Defining how all these arguments
interact when various combinations are present is difficult.
This commit establishes a new, generic mechanism for specifying
revisions. Instead of a hodgepodge of arguments defining things, we
have a list of dicts that specify revision selectors. The final set
of revisions is a union of all these selectors.
We implement support for specifying revisions based on:
* An explicit list of changeset revisions
* An explicit list of changeset revisions plus ancestry depth
* A DAG range between changeset roots and heads
If you squint hard enough, this problem has already been solved by
revsets. But I'm reluctant to expose revsets to the wire protocol
because that would require servers to implement a revset parser.
Plus there are security and performance implications: the set
of revision selectors needs to be narrowly and specifically tailored
for what is appropriate to be executing on a server. Perhaps there
would be a way for us to express the "parse tree" of a revset
query, for example. I'm not sure. We can explore this space another
time. For now, the new mechanism should bring sufficient flexibility
while remaining relatively simple.
The selector "types" are prefixed with "changeset" because I plan
to add manifest and file-flavored selectors as well. This will enable
us to e.g. select file revisions based on a range of changeset
revisions.

Additional tricky linkrev case ------------------------------ If the first file revision after the diff base has a linkrev pointing to a changeset on another branch with a revision lower that the diff base, we can jump past the copy detection limit and fail to detect the rename. $ hg init diffstoplinkrev $ cd diffstoplinkrev $ touch f $ hg ci -Aqm 'empty f' Make a simple change $ echo change > f $ hg ci -m 'change f' Make a second branch, we use a named branch to create a simple commit that does not touch f. $ hg up -qr 'desc(empty)' $ hg branch -q dev $ hg ci -Aqm dev Graft the initial change, as f was untouched, we reuse the same entry and the linkrev point to the older branch. $ hg graft -q 'desc(change)' Make a rename because we want to track renames.
