global: bulk replace simple pycompat.iteritems(x) with x.items() pycompat.iteritems() just calls .items(). This commit applies a regular expression search and replace to convert simple instances of pycompat.iteritems() with .items(). There are still a handful of calls to pycompat.iteritems() remaining. But these all have more complicated expressions that I wasn't comfortable performing an automated replace on. In addition, some simple replacements were withheld because they broke pytype. These will be handled by their own changesets. Differential Revision: https://phab.mercurial-scm.org/D12318

worker: silence type error when calling pickle pytype is complaining that the argument to `pickle.load()` is not an `IO`. pytype isn't wrong: `_blockingreader` doesn't implement `io.RawIOBase`, only `read()` and `readline()`. But it appears this is enough for pickle. So we silence the false positive. This fixes a regression introduced by D12304 / cc0e059d2af8: worker: remove Python 2 support code.
