chg: fallback to original hg if stdio fds are missing

If stdio fds are missing (ex. fd 0 is not present), chg might open
fds that take the numbers 0, and attachio would send the wrong fds
to the client, which might cause unwanted behaviors. Avoid that by
detecting the missing fds and falling back to the original hg.

create cvs repository

  $ mkdir cvsrepo
  $ cd cvsrepo
  $ CVSROOT=`pwd`
  $ export CVSROOT
  $ CVS_OPTIONS=-f
  $ export CVS_OPTIONS
  $ cd ..
  $ rmdir cvsrepo
  $ cvscall -q -d "$CVSROOT" init

Create a new project

  $ mkdir src
  $ cd src
  $ echo "1" > a
  $ echo "1" > b
  $ cvscall import -m "init" src v0 r0 | sort
  $ cd ..
  $ cvscall co src
  cvs checkout: Updating src
  $ cd src

Branch the project

  $ cvscall tag -b BRANCH
  cvs tag: Tagging .
  $ cvscall up -r BRANCH > /dev/null
  cvs update: Updating .

Modify file a, then b, then a

  $ sleep 1
  $ echo "2" > a
  $ cvscall ci -m "mod a"
  cvs commit: Examining .
  $ echo "2" > b
  $ cvscall ci -m "mod b"
  cvs commit: Examining .
  $ sleep 1
  $ echo "3" > a
  $ cvscall ci -m "mod a again"
  cvs commit: Examining .
