packaging: update dulwich to drop the certifi dependency on Windows
The presence of `certifi` causes the system certificate store to be ignored,
which was reported as a bug against TortoiseHg[1]. It was only pulled in on
Windows because of `dulwich`, which was copied from the old TortoiseHg install
scripts, in order to support `hg-git`.
This version of `dulwich` raises the minimum `urllib3` to a version (1.25) that
does certificate verification by default, without the help of `certifi`[2]. We
already bundle a newer version of `urllib3`. Note that `certifi` can still be
imported from the user site directory, if installed there. But the installer no
longer disables the system certificates by default.

Test that the syntax of "unified tests" is properly processed
==============================================================
Simple commands:
$ echo foo
foo
$ printf 'oh no'
oh no (no-eol)
$ printf 'bar\nbaz\n' | cat
bar
baz
Multi-line command:
$ foo() {
> echo bar
> }
$ foo
bar
Return codes before inline python:
$ sh -c 'exit 1'
[1]
Doctest commands:
>>> print('foo')
foo
$ echo interleaved
interleaved
>>> for c in 'xyz':
... print(c)
x
y
z
>>> print()
>>> foo = 'global name'
>>> def func():
... print(foo, 'should be visible in func()')
>>> func()
global name should be visible in func()
>>> print('''multiline
... string''')
multiline
string
Regular expressions:
$ echo foobarbaz
foobar.* (re)
$ echo barbazquux
.*quux.* (re)
Globs:
$ printf '* \\foobarbaz {10}\n'
\* \\fo?bar* {10} (glob)
Literal match ending in " (re)":
$ echo 'foo (re)'
foo (re)
Windows: \r\n is handled like \n and can be escaped:
#if windows
$ printf 'crlf\r\ncr\r\tcrlf\r\ncrlf\r\n'
crlf
cr\r (no-eol) (esc)
\tcrlf (esc)
crlf\r (esc)
#endif
Escapes:
$ "$PYTHON" -c 'from mercurial.utils.procutil import stdout; stdout.write(b"\xff")'
\xff (no-eol) (esc)
Escapes with conditions:
$ "$PYTHON" -c 'from mercurial.utils.procutil import stdout; stdout.write(b"\xff")'
\xff (no-eol) (esc) (true !)
Combining esc with other markups - and handling lines ending with \r instead of \n:
$ printf 'foo/bar\r'
fo?/bar\r (no-eol) (glob) (esc)
#if windows
$ printf 'foo\\bar\r'
foo/bar\r (no-eol) (esc)
#endif
$ printf 'foo/bar\rfoo/bar\r'
foo.bar\r [(]no-eol[)] (re) (esc)
foo.bar\r \(no-eol\) (re)
testing hghave
$ hghave true
$ hghave false
skipped: missing feature: nail clipper
[1]
$ hghave no-true
skipped: system supports yak shaving
[1]
$ hghave no-false
Conditional sections based on hghave:
#if true
$ echo tested
tested
#else
$ echo skipped
#endif
#if false
$ echo skipped
#else
$ echo tested
tested
#endif
#if no-false
$ echo tested
tested
#else
$ echo skipped
#endif
#if no-true
$ echo skipped
#else
$ echo tested
tested
#endif
Exit code:
$ (exit 1)
