context: remove basectx.__int__ (API)

basectx is the only type in the repo having __int__ implemented.

This magic method can result in unexpected coercion. Furthermore,
having it implemented is wrong for some contexts, since rev() may
return None in some cases.

Previous commits removed known cases in core where contexts are
coerced to integers. So let's delete basectx.__int__.

This commit is a bit dangerous. While the test suite passes, there
are likely still some callers in core that rely on __int__ that
don't have test coverage. An alternative would be to issue a
deprecation warning and let this bake for a few releases.

.. api::

   context.basectx no longer implements __int__. Context instances
   will no longer cast to ints. Consumers should call ``ctx.rev()``
   instead.

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:

  >>> from __future__ import print_function
  >>> 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

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)
