filemerge: make `_maketempfiles()` more reusable

`_maketempfiles()` is very specialized for its current use. I hope to
use it also when creating temporary files for input for tools that do
partial conflict resolution. That'll be possible if the function is
more generic. Instead of passing in two contexts (for "other" and
"base") and an optional path (for "local"), let's pass a single list
of files to make backups for. Even if we don't end up using for
partial conflict resolution, this is still a simplification (but I do
have a WIP patch for partial conflict resolution and it is able to
benefit from this).

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

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)
  [1]
