tag: invalidate tag cache immediately after adding new tag (issue3210)

New tags were written to .hgtags / .hglocaltags without updating or
invalidating the localrepo cache.

Before afd459933d5f a lock was acquired soon after the new tags had been
written, and that invalidated the cache so the new tags for example could be
seen in pretxncommit hooks. With afd459933d5f the lock had already been
acquired at this point and the missing cache invalidation was exposed.

The tag caches will now explicitly and immediately be invalidated when new tags
are added.

Mercurial's internal web server, hgweb, can serve either a single
repository, or a collection of them. In the latter case, a special
configuration file can be used to specify the repository paths to use
and global web configuration options.

This file uses the same syntax as other Mercurial configuration files,
but only the following sections are recognized:

  - web
  - paths
  - collections

The ``web`` section can specify all the settings described in the web
section of the hgrc(5) documentation. See :hg:`help config` for
information on where to find the manual page.

The ``paths`` section provides mappings of physical repository
paths to virtual ones. For instance::

  [paths]
  projects/a = /foo/bar
  projects/b = /baz/quux
  web/root = /real/root/*
  / = /real/root2/*
  virtual/root2 = /real/root2/**

- The first two entries make two repositories in different directories
  appear under the same directory in the web interface
- The third entry maps every Mercurial repository found in '/real/root'
  into 'web/root'. This format is preferred over the [collections] one,
  since using absolute paths as configuration keys is not supported on every
  platform (especially on Windows).
- The fourth entry is a special case mapping all repositories in
  '/real/root2' in the root of the virtual directory.
- The fifth entry recursively finds all repositories under the real
  root, and maps their relative paths under the virtual root.

The ``collections`` section provides mappings of trees of physical
repositories paths to virtual ones, though the paths syntax is generally
preferred. For instance::

  [collections]
  /foo = /foo

Here, the left side will be stripped off all repositories found in the
right side. Thus ``/foo/bar`` and ``foo/quux/baz`` will be listed as
``bar`` and ``quux/baz`` respectively.
