statichttprepo: stop shadowing the `bytes` builtin

PyCharm flagged it, but I also misunderstood when looking at the code, because
the name implied a byte string, not a number.

  $ hg init repo
  $ cd repo
  $ echo 123 > a
  $ echo 123 > c
  $ echo 123 > e
  $ hg add a c e
  $ hg commit -m "first" a c e

nothing changed

  $ hg revert
  abort: no files or directories specified
  (use --all to revert all files)
  [10]
  $ hg revert --all

Introduce some changes and revert them
--------------------------------------

  $ echo 123 > b

  $ hg status
  ? b
  $ echo 12 > c

  $ hg status
  M c
  ? b
  $ hg add b

  $ hg status
  M c
  A b
  $ hg rm a

  $ hg status

revert removal of a file

  $ hg revert a
  $ hg status
  M c
  A b

revert addition of a file

  $ hg revert b
  $ hg status

  ? b

revert modification of a file (--no-backup)

  $ hg revert --no-backup c
  $ hg status

revert deletion (! status) of a added file
------------------------------------------

  $ hg add b

  $ hg status b

  $ rm b
  $ hg status b
  ! b
  $ hg revert -v b
  forgetting b
  $ hg status b

Test creation of backup (.orig) files
-------------------------------------

  $ echo z > e
  $ hg revert --all -v
  saving current version of e as e.orig
  reverting e

Test creation of backup (.orig) file in configured file location
----------------------------------------------------------------

  $ echo z > e
  $ hg revert --all -v --config 'ui.origbackuppath=.hg/origbackups'
  creating directory: $TESTTMP/repo/.hg/origbackups
  saving current version of e as .hg/origbackups/e
  reverting e
  $ rm -rf .hg/origbackups

revert on clean file (no change)
--------------------------------

  $ hg revert a
  no changes needed to a

revert on an untracked file
---------------------------

  $ echo q > q
  $ hg revert q
  file not managed: q
  $ rm q

revert on file that does not exists
-----------------------------------

  $ hg revert notfound
  notfound: no such file in rev 334a9e57682c
  $ touch d
  $ hg add d
  $ hg rm a
  $ hg commit -m "second"
  $ echo z > z
  $ hg add z
  $ hg st
  A z
  ? e.orig

revert to another revision (--rev)
----------------------------------

  $ hg revert --all -r0
  forgetting z
  removing d
  adding a

revert explicitly to parent (--rev)
-----------------------------------

  $ hg revert --all -rtip
  forgetting a
  undeleting d
  $ rm a *.orig

revert to another revision (--rev) and exact match
--------------------------------------------------

exact match are more silent

  $ hg revert -r0 a
  $ hg st a
  A a
  $ hg rm d
  $ hg st d
  R d

should keep d removed

  $ hg revert -r0 d
  no changes needed to d
  $ hg st d
  R d

  $ hg update -C
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

revert of exec bit
------------------

#if execbit
  $ chmod +x c
  $ hg revert --all
  reverting c

  $ test -x c || echo non-executable
  non-executable

  $ chmod +x c
  $ hg commit -m exe

  $ chmod -x c
  $ hg revert --all
  reverting c

  $ test -x c && echo executable
  executable
#endif

Test that files reverted to other than the parent are treated as
"modified", even if none of mode, size and timestamp of it isn't
changed on the filesystem (see also issue4583).

Systematic behavior validation of most possible cases
=====================================================

This section tests most of the possible combinations of revision states and
working directory states. The number of possible cases is significant but they
but they all have a slightly different handling. So this section commits to
and testing all of them to allow safe refactoring of the revert code.

A python script is used to generate a file history for each combination of
states, on one side the content (or lack thereof) in two revisions, and
on the other side, the content and "tracked-ness" of the working directory. The
three states generated are:

- a "base" revision
- a "parent" revision
- the working directory (based on "parent")

The files generated have names of the form:

 <rev1-content>_<rev2-content>_<working-copy-content>-<tracked-ness>

All known states are not tested yet. See inline documentation for details.
Special cases from merge and rename are not tested by this section.

Write the python script to disk

  > for filename in files:

The diff is filtered to include change only. The only difference should be
additional `.orig` backup file when applicable.

actual tests: reverting to something else than a merge parent

  $ hg merge
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

  $ hg status --rev 'p1()'
  M A
  $ hg status --rev 'p2()'
  A B
  $ hg status --rev '1'
  M A
  A B
  $ hg revert --rev 1 --all
  removing B
  reverting A
  $ hg status --rev 1

From the other parents

  $ hg up -C 'p2()'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg merge
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
