[PATCH 0/6] git p4 error handling

These are assorted minor fixes. They should be safe for 1.8.1, and are not urgent enough for maint.

Four of them deal with handling errors from p4d better. The first two of these have been seen on the list already. The third showed up in my own testing. The fourth adds a test to make sure that existing error handling continues to work.

  git p4: catch p4 describe errors
  git p4: handle servers without move support
  git p4: catch p4 errors when streaming file contents
  git p4 test: display unresolvable host error

These two are small cleanups found by pylint, one of which is an obvious (but rare) bug.

  git p4: fix labelDetails typo in exception
  git p4: remove unneeded cmd initialization
