add: notify when adding a file that would cause a case-folding collision

On a case-sensitive file system, files can be added with names that differ
only in case (a "case collision"). This would cause an error on case-insensitive
filesystems. A warning or error is now given for such collisions, depending on
the value of ui.portablefilenames ('warn', 'abort', or 'ignore'):

    $ touch file File
    $ hg add --config ui.portablefilenames=abort File
    abort: possible case-folding collision for File
    $ hg add File
    warning: possible case-folding collision for File

run only on case-sensitive filesystems

  $ "$TESTDIR/hghave" no-icasefs || exit 80

test file addition with colliding case

  $ hg init repo1
  $ cd repo1
  $ echo a > a
  $ echo A > A
  $ hg add a
  $ hg st
  A a
  ? A
  $ hg add --config ui.portablefilenames=abort A
  abort: possible case-folding collision for A
