hgweb: support Content Security Policy

Content-Security-Policy (CSP) is a web security feature that allows
servers to declare what loaded content is allowed to do. For example,
a policy can prevent loading of images, JavaScript, CSS, etc unless
the source of that content is whitelisted (by hostname, URI scheme,
hashes of content, etc). It's a nifty security feature that provides
extra mitigation against some attacks, notably XSS.

Mitigation against these attacks is important for Mercurial because
hgweb renders repository data, which is commonly untrusted. While we
make attempts to escape things, etc, there's the possibility that
malicious data could be injected into the site content. If this happens
today, the full power of the web browser is available to that
malicious content. A restrictive CSP policy (defined by the server
operator and sent in an HTTP header which is outside the control of
malicious content), could restrict browser capabilities and mitigate
security problems posed by malicious data.

CSP works by emitting an HTTP header declaring the policy that browsers
should apply. Ideally, this header would be emitted by a layer above
Mercurial (likely the HTTP server doing the WSGI "proxying"). This
works for some CSP policies, but not all.

For example, policies to allow inline JavaScript may require setting
a "nonce" attribute on <script>. This attribute value must be unique
and non-guessable. And, the value must be present in the HTTP header
and the HTML body. This means that coordinating the value between
Mercurial and another HTTP server could be difficult: it is much
easier to generate and emit the nonce in a central location.

This commit introduces support for emitting a
Content-Security-Policy header from hgweb. A config option defines
the header value. If present, the header is emitted. A special
"%nonce%" syntax in the value triggers generation of a nonce and
inclusion in <script> elements in templates. The inclusion of a
nonce does not occur unless "%nonce%" is present. This makes this
commit completely backwards compatible and the feature opt-in.

The nonce is a type 4 UUID, which is the flavor that is randomly
generated. It has 122 random bits, which should be plenty to satisfy
the guarantees of a nonce.

  $ hg help mq
  mq extension - manage a stack of patches
  
  This extension lets you work with a stack of patches in a Mercurial
  repository. It manages two stacks of patches - all known patches, and applied
  patches (subset of known patches).
  
  Known patches are represented as patch files in the .hg/patches directory.
  Applied patches are both patch files and changesets.
  
  Common tasks (use 'hg help command' for more details):
  
    create new patch                          qnew
    import existing patch                     qimport
  
    print patch series                        qseries
    print applied patches                     qapplied
  
    add known patch to applied stack          qpush
    remove patch from applied stack           qpop
    refresh contents of top applied patch     qrefresh
  
  By default, mq will automatically use git patches when required to avoid
  losing file mode changes, copy records, binary files or empty files creations
  or deletions. This behavior can be configured with:
  
    [mq]
    git = auto/keep/yes/no
  
  If set to 'keep', mq will obey the [diff] section configuration while
  preserving existing git patches upon qrefresh. If set to 'yes' or 'no', mq
  will override the [diff] section and always generate git or regular patches,
  possibly losing data in the second case.
  
  It may be desirable for mq changesets to be kept in the secret phase (see 'hg
  help phases'), which can be enabled with the following setting:
  
    [mq]
    secret = True
  
  You will by default be managing a patch queue named "patches". You can create
  other, independent patch queues with the 'hg qqueue' command.
  
  If the working directory contains uncommitted files, qpush, qpop and qgoto
  abort immediately. If -f/--force is used, the changes are discarded. Setting:
  
    [mq]
    keepchanges = True
  
  make them behave as if --keep-changes were passed, and non-conflicting local
  changes will be tolerated and preserved. If incompatible options such as
  -f/--force or --exact are passed, this setting is ignored.
  
  This extension used to provide a strip command. This command now lives in the
  strip extension.
  
  list of commands:
  
   qapplied      print the patches already applied
   qclone        clone main and patch repository at same time
   qdelete       remove patches from queue
   qdiff         diff of the current patch and subsequent modifications
   qfinish       move applied patches into repository history
   qfold         fold the named patches into the current patch
   qgoto         push or pop patches until named patch is at top of stack
   qguard        set or print guards for a patch
   qheader       print the header of the topmost or specified patch
   qimport       import a patch or existing changeset
   qnew          create a new patch
   qnext         print the name of the next pushable patch
   qpop          pop the current patch off the stack
   qprev         print the name of the preceding applied patch
   qpush         push the next patch onto the stack
   qqueue        manage multiple patch queues
   qrefresh      update the current patch
   qrename       rename a patch
   qselect       set or print guarded patches to push
   qseries       print the entire series file
   qtop          print the name of the current patch
   qunapplied    print the patches not yet applied
