bundle2: implement consume() API on unbundlepart

We want bundle parts to not be seekable by default. That means
eliminating the generic seek() method.

A common pattern in bundle2.py is to seek to the end of the part
data. This is mainly used by the part iteration code to ensure
the underlying stream is advanced to the next bundle part.

In this commit, we establish a dedicated API for consuming a
bundle2 part data. We switch users of seek() to it.

The old implementation of seek(0, os.SEEK_END) would effectively
call self.read(). The new implementation calls self.read(32768)
in a loop. The old implementation would therefore assemble a
buffer to hold all remaining data being seeked over. For seeking
over large bundle parts, this would involve a large allocation and
a lot of overhead to collect intermediate data! This overhead can
be seen in the results for `hg perfbundleread`:

! bundle2 iterparts()
! wall 10.891305 comb 10.820000 user 7.990000 sys 2.830000 (best of 3)
! wall 8.070791 comb 8.060000 user 7.180000 sys 0.880000 (best of 3)
! bundle2 part seek()
! wall 12.991478 comb 10.390000 user 7.720000 sys 2.670000 (best of 3)
! wall 10.370142 comb 10.350000 user 7.430000 sys 2.920000 (best of 3)

Of course, skipping over large payload data isn't likely very common.
So I doubt the performance wins will be observed in the wild.

  $ hg help mq
  mq extension - manage a stack of patches
  
  This extension lets you work with a stack of patches in a Mercurial
  repository. It manages two stacks of patches - all known patches, and applied
  patches (subset of known patches).
  
  Known patches are represented as patch files in the .hg/patches directory.
  Applied patches are both patch files and changesets.
  
  Common tasks (use 'hg help COMMAND' for more details):
  
    create new patch                          qnew
    import existing patch                     qimport
  
    print patch series                        qseries
    print applied patches                     qapplied
  
    add known patch to applied stack          qpush
    remove patch from applied stack           qpop
    refresh contents of top applied patch     qrefresh
  
  By default, mq will automatically use git patches when required to avoid
  losing file mode changes, copy records, binary files or empty files creations
  or deletions. This behavior can be configured with:
  
    [mq]
    git = auto/keep/yes/no
  
  If set to 'keep', mq will obey the [diff] section configuration while
  preserving existing git patches upon qrefresh. If set to 'yes' or 'no', mq
  will override the [diff] section and always generate git or regular patches,
  possibly losing data in the second case.
  
  It may be desirable for mq changesets to be kept in the secret phase (see 'hg
  help phases'), which can be enabled with the following setting:
  
    [mq]
    secret = True
  
  You will by default be managing a patch queue named "patches". You can create
  other, independent patch queues with the 'hg qqueue' command.
  
  If the working directory contains uncommitted files, qpush, qpop and qgoto
  abort immediately. If -f/--force is used, the changes are discarded. Setting:
  
    [mq]
    keepchanges = True
  
  make them behave as if --keep-changes were passed, and non-conflicting local
  changes will be tolerated and preserved. If incompatible options such as
  -f/--force or --exact are passed, this setting is ignored.
  
  This extension used to provide a strip command. This command now lives in the
  strip extension.
  
  list of commands:
  
   qapplied      print the patches already applied
   qclone        clone main and patch repository at same time
   qdelete       remove patches from queue
   qdiff         diff of the current patch and subsequent modifications
   qfinish       move applied patches into repository history
   qfold         fold the named patches into the current patch
   qgoto         push or pop patches until named patch is at top of stack
   qguard        set or print guards for a patch
   qheader       print the header of the topmost or specified patch
   qimport       import a patch or existing changeset
   qnew          create a new patch
   qnext         print the name of the next pushable patch
   qpop          pop the current patch off the stack
   qprev         print the name of the preceding applied patch
   qpush         push the next patch onto the stack
   qqueue        manage multiple patch queues
   qrefresh      update the current patch
   qrename       rename a patch
   qselect       set or print guarded patches to push
   qseries       print the entire series file
   qtop          print the name of the current patch
   qunapplied    print the patches not yet applied
