add: pass full=False to dirstate walk

Previously cmdutil.add would call wctx.walk(), which under the hood calls
dirstate.walk with full=True. This means it returns all of the clean files
(which we don't need when computing the add set), as well as the unclean files.
This results in 1) a lot more work being done and 2) this code path
circumventing the hgwatchman extension, resulting in worse performance in
hgwatchman environments ('hg add .' went from 9s to 1.8s).

  use 'echo' to diff repository (or selected files)
  
      Show differences between revisions for the specified files, using the
      'echo' program.
  
      When two revision arguments are given, then changes are shown between
      those revisions. If only one revision is specified then that revision is
      compared to the working directory, and, when no revisions are specified,
      the working directory files are compared to its parent.
  
  options ([+] can be repeated):
  
   -o --option OPT [+]      pass option to comparison program
   -r --rev REV [+]         revision
   -c --change REV          change made by revision
   -I --include PATTERN [+] include names matching the given patterns
   -X --exclude PATTERN [+] exclude names matching the given patterns
   -S --subrepos            recurse into subrepositories

Should diff cloned files directly:

Test diff during merge:

  $ hg update -C 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo c >> c
  $ hg add c
  $ hg ci -m "new branch" -d '1 0'
  created new head
  $ hg merge 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

Should diff cloned file against wc file:

#if windows
  $ hg falabala

  [1]
#else
  $ hg falabala
