dirstate: only call lstat once per flags invocation This makes a big difference to performance in some cases. hg --time locate 'set:symlink()' mozilla-central (70,000 files): before: 2.92 sec after: 2.47 another repo (170,000 files): before: 7.87 sec after: 6.86

util: add functions to check symlink/exec bits These are not yet used.

setup.py: properly discard trust warning. This modification was missing from the fa91ddfc3f36 changeset.

scmutil.addremove: use iteritems on walk results Now that we no longer sort all the walk results, using iteritems becomes possible. This is a relatively minor speedup: on a large repository with 170,000 files, perfaddremove goes from 2.13 seconds to 2.10.

scmutil.addremove: stop sorting all walk results The only place where the order matters is in printing out added or removed files. We already sort that set. On a large repository with 170,000 files, this speeds up perfaddremove from 2.34 seconds to 2.13.
