hgweb: add a "URL breadcrumb" to the index and repository pages

The purpose of this change is to make it much easier to navigate up the
repository tree when the hg web server is used to serve more than one
repository.

A "URL breadcrumb" is a path where each of the path items can be clicked to go
to the corresponding path page.

This lets you go up the folder hierarchy very quickly. For example, when showing
the list of repositories in http://myserver/myteams/myprojects, the following
"breadcrumb" will be shown:

Mercurial > myteams > myprojects

Clicking on "myprojects" reloads the page. Clicking on "myteams" goes up one
folder. Clicking on the leftmost "Mercurial" goes to the server root.

This "breadcrumb" also appears on all repository pages. For example on the
summary page of the repository at http://myserver/myteams/myprojects/myrepo the
following will be shown:

Mercurial > myteams > myprojects > myrepo / summary

This change has been applied to all templates that already had a link to the
main repository page (i.e. gitweb, monoblue, paper and coal) plus to the index
page of the spartan template.

In order to make the breadcumb links stand out the some of the template styles
have been customized.

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
  

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'
  foo/bar\r (no-eol) (glob) (esc)
#if windows
  $ printf 'foo\\bar\r'
  foo/bar\r (no-eol) (glob) (esc)
#endif
  $ printf 'foo/bar\rfoo/bar\r'
  foo.bar\r \(no-eol\) (re) (esc)
  foo.bar\r \(no-eol\) (re)

testing hghave

  $ "$TESTDIR/hghave" true
  $ "$TESTDIR/hghave" false
  skipped: missing feature: nail clipper
  [1]
  $ "$TESTDIR/hghave" no-true
  skipped: system supports yak shaving
  [1]
  $ "$TESTDIR/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)
