shelve: teach new shelf class to check if .shelve file exists
This removes the only remaining use for `shelvedfile`, so the class
now goes away.

Test the extensions.afterloaded() function
$ cat > foo.py <<EOF
> from mercurial import extensions
> def uisetup(ui):
> ui.write(b"foo.uisetup\\n")
> ui.flush()
> def bar_loaded(loaded):
> ui.write(b"foo: bar loaded: %r\\n" % (loaded,))
> ui.flush()
> extensions.afterloaded(b'bar', bar_loaded)
> EOF
$ cat > bar.py <<EOF
> def uisetup(ui):
> ui.write(b"bar.uisetup\\n")
> ui.flush()
> EOF

Test afterloaded with the opposite extension load order
$ cd ..
$ hg init basic_reverse
$ cd basic_reverse
$ echo foo > file
$ hg add file
$ hg commit -m 'add file'
$ echo '[extensions]' >> .hg/hgrc
$ echo "bar = $basepath/bar.py" >> .hg/hgrc
$ echo "foo = $basepath/foo.py" >> .hg/hgrc
$ hg log -r. -T'{rev}\n'
bar.uisetup
foo.uisetup
foo: bar loaded: True
0
Test the extensions.afterloaded() function when the requested extension is not
loaded
$ cd ..
$ hg init notloaded
$ cd notloaded
$ echo foo > file
$ hg add file
$ hg commit -m 'add file'
$ echo '[extensions]' >> .hg/hgrc
$ echo "foo = $basepath/foo.py" >> .hg/hgrc
$ hg log -r. -T'{rev}\n'
foo.uisetup
foo: bar loaded: False

Test the extensions.afterloaded() function when the requested extension is not
configured but fails the minimum version check
$ cd ..
$ cat > minvers.py <<EOF
> minimumhgversion = b'9999.9999'
> def uisetup(ui):
> ui.write(b"minvers.uisetup\\n")
> ui.flush()
> EOF
$ hg init minversion
$ cd minversion
$ echo foo > file
$ hg add file
$ hg commit -m 'add file'
$ echo '[extensions]' >> .hg/hgrc
$ echo "foo = $basepath/foo.py" >> .hg/hgrc
$ echo "bar = $basepath/minvers.py" >> .hg/hgrc
$ hg log -r. -T'{rev}\n'
(third party extension bar requires version 9999.9999 or newer of Mercurial (current: *); disabling) (glob)

Test the extensions.afterloaded() function when the requested extension is not
configured but fails the minimum version check, using the opposite load order
for the two extensions.
$ cd ..
