errors: introduce CanceledError and use it in a few places
This very similar to earlier patches (e.g. for `InputError`) and part
of https://www.mercurial-scm.org/wiki/ErrorCategoriesPlan.

transaction: split new files into a separate set
Journal entries with size 0 are common as they represent new revlog
files. Move them from the dictionary into a set as the former is more
dense. This reduces peak RSS by 70MB for the NetBSD test repository with
around 450k files under .hg/store.

transaction: change list of journal entries into a dictionary
The transaction object used to keep a mapping table of path names to
journal entries and a list of journal entries consisting of path and
file offset to truncate on rollback. The offsets are used in three
cases. repair.strip and rollback process all of them in one go, but they
care about the order. For them, it is perfectly reasonable to read the
journal back from disk as both operations already involve at least one
system call per journal entry. The other consumer is the revlog logic
for moving from inline to external data storage. It doesn't care about
the order of the journal and just needs to original offset stored.
Further optimisations are possible here to move the in-memory journal to
a set(), but without memoisation of the original revlog size this could
turn it into O(n^2) behavior in worst case when many revlogs need to
migrated.

transaction: rename find to findoffset and drop backup file support
transaction.find used to support access to both the regular file and
backup file list. They have different formats, so any consumer has to be
aware of the difference alredy. There is no in-core consumer for the
backup file access, so don't provide it.

transaction: drop per-file extra data support
At the moment, transactions support an optional extra data argument for
all files to be stored in addition to the original offset. This is used
in core only by the revlog inline to external data migration. It is used
to memoize the number of revisions before the transaction. That number
of can be computed during the walk easily, so drop the requirement.
