bundle2: urlquote stream parameter name and value

This introduces support for arbitrary characters in stream parameters name and
value.  The urlquote format has been chosen because it is:

- simple,
- standard,
- no-op on simple alphanumerical entry.

The extension requires a repo (currently unused)

  $ hg init main
  $ cd main
  $ touch a
  $ hg add a
  $ hg commit -m 'a'


Empty bundle
=================

- no option
- no parts

Test bundling

  $ hg bundle2
  HG20\x00\x00\x00\x00 (no-eol) (esc)

Test unbundling

  $ hg bundle2 | hg unbundle2
  options count: 0
  parts count:   0

Test old style bundle are detected and refused

  $ hg bundle --all ../bundle.hg
  1 changesets found
  $ hg unbundle2 < ../bundle.hg
  abort: unknown bundle version 10
  [255]

Test parameters
=================

- some options
- no parts

advisory parameters, no value
-------------------------------

Simplest possible parameters form

Test generation simple option

  $ hg bundle2 --param 'caution'
  HG20\x00\x07caution\x00\x00 (no-eol) (esc)

Test unbundling

  $ hg bundle2 --param 'caution' | hg unbundle2
  options count: 1
  - caution
  parts count:   0

Test generation multiple option

  $ hg bundle2 --param 'caution' --param 'meal'
  HG20\x00\x0ccaution meal\x00\x00 (no-eol) (esc)

Test unbundling

  $ hg bundle2 --param 'caution' --param 'meal' | hg unbundle2
  options count: 2
  - caution
  - meal
  parts count:   0

advisory parameters, with value
-------------------------------

Test generation

  $ hg bundle2 --param 'caution' --param 'meal=vegan' --param 'elephants'
  HG20\x00\x1ccaution meal=vegan elephants\x00\x00 (no-eol) (esc)

Test unbundling

  $ hg bundle2 --param 'caution' --param 'meal=vegan' --param 'elephants' | hg unbundle2
  options count: 3
  - caution
  - elephants
  - meal
      vegan
  parts count:   0

parameter with special char in value
