py3: use io.BytesIO directly

Previously, pycompat.bytesio and pycompat.stringio referred to
io.BytesIO. And util.bytesio and util.stringio aliased the pycompat
symbols.

This commit switches everything to use io.BytesIO directly. util.bytesio
and util.stringio still exist to provide backwards compatibility, as
they were the preferred symbols.

subsetparents: p1/p2 order
-------------------------

  $ cd named-branch-order

Parents should be sorted in p1/p2 order since p1 is likely to belong to
the same named branch:

  $ hg log -Gq -T '{rev} {tags}: {subsetparents(rev, revset("0+1+2+6"))}\n' -r '0+1+2+6'
  o    6 : 2 1 0
  :\
  : \
  : :\
  : : o  2 :
  : :
  : o  1 :
  :
  o  0 :
  

  $ hg log -Gq -T '{rev} {tags}: {subsetparents(rev, revset("0+1+2+6+10"))}\n' -r '0+1+2+6+10'
  @    10 tip: 6
  :\
  : o    6 : 2 1 0
  :/:\
  : : o  2 :
  : :
  o :  1 :
   /
  o  0 :
  

And p1 path should be selected if both p1/p2 paths exist:

  $ hg log -Gq -T '{rev} {tags}: {subsetparents(rev, revset("0+1+2+10"))}\n' -r '0+1+2+10'
  @    10 tip: 1 2 0

  : : o  2 :

  o :  1 :

  o  0 :
