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.

Create user cache directory

  $ USERCACHE=`pwd`/cache; export USERCACHE
  $ cat <<EOF >> ${HGRCPATH}
  > [extensions]
  > hgext.largefiles=
  > [largefiles]
  > usercache=${USERCACHE}
  > EOF
  $ mkdir -p ${USERCACHE}

Create source repo, and commit adding largefile.

  $ hg init src
  $ cd src
  $ echo large > large
  $ hg add --large large
  $ hg commit -m 'add largefile'
  $ cd ..

Discard all cached largefiles in USERCACHE

  $ rm -rf ${USERCACHE}

Create mirror repo, and pull from source without largefile:
"pull" is used instead of "clone" for suppression of (1) updating to
tip (= cahcing largefile from source repo), and (2) recording source
repo as "default" path in .hg/hgrc.

  $ hg init mirror
  $ cd mirror
  $ hg pull ../src
  pulling from ../src
  requesting all changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files
  (run 'hg update' to get a working copy)
  caching new largefiles
  0 largefiles cached

Update working directory to "tip", which requires largefile("large"),
but there is no cache file for it.  So, hg must treat it as
"missing"(!) file.

  $ hg update
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  getting changed largefiles
  large: Can't get file locally
  (no default or default-push path set in hgrc)
  0 largefiles updated, 0 removed
  $ hg status
  ! large

Update working directory to null: this cleanup .hg/largefiles/dirstate

  $ hg update null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  getting changed largefiles
  0 largefiles updated, 0 removed

Update working directory to tip, again.

  $ hg update
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  getting changed largefiles
  large: Can't get file locally
  (no default or default-push path set in hgrc)
  0 largefiles updated, 0 removed
  $ hg status
  ! large
