setup: build C extensions with -Werror=declaration-after-statement

MSVC 2008 still needs declarations at the top of the scope.  I added it to the
3rd party code too in case somebody vendors a new version with a problem-
they'll get an early warning.  Clang seems to ignore this (at least on 10.14
with Xcode 10), and gcc 7.4 will error out as desired on Ubuntu 18.04.  Thanks
to Yuya for remembering the name of the option.

Build a GIT repo with at least 1 tag

  $ mkdir git-repo
  $ cd git-repo
  $ git init >/dev/null 2>&1
  $ echo a > a
  $ git add a
  $ action commit -m "rev1"
  $ action tag -m "tag1" tag1
  $ cd ..

Convert without tags

  $ hg convert git-repo hg-repo --config convert.skiptags=True
  initializing destination hg-repo repository
  scanning source...
  sorting...
  converting...
  0 rev1
  updating bookmarks
  $ hg -R hg-repo tags
  tip                                0:d98c8ad3a4cf
  $ rm -rf hg-repo

Do a first conversion

  $ convertrepo
  initializing destination hg-repo repository
  scanning source...
  sorting...
  converting...
  0 rev1
  updating tags
  updating bookmarks

Simulate upstream  updates after first conversion

  $ cd git-repo
  $ echo b > a
  $ git add a
  $ action commit -m "rev2"
  $ action tag -m "tag2" tag2
  $ cd ..

Perform an incremental conversion

  $ convertrepo
  scanning source...
  sorting...
  converting...
  0 rev2
  updating tags
  updating bookmarks

Print the log

  $ cd hg-repo
  $ glog
  o  3 "update tags" files: .hgtags
  |
  | o  2 "rev2" files: a
  | |
  o |  1 "update tags" files: .hgtags
   /
  o  0 "rev1" files: a
  

  $ cd ..
