node: import symbols explicitly

There is no point in lazy importing mercurial.node, it is used all over
the place anyway. So consistently import the used symbols directly.
Fix one file using symbols indirectly via mercurial.revlog.

Test applying context diffs

  > lasteol = sys.argv[2] == '1'
  > patterns = sys.argv[3:]
  > 
  > fp = open(path, 'wb')
  > for i, pattern in enumerate(patterns):
  >     count = int(pattern[0:-1])
  >     char = pattern[-1].encode('utf8') + b'\n'
  >     if not lasteol and i == len(patterns) - 1:
  >         fp.write((char * count)[:-1])
  >     else:
  >         fp.write(char * count)
  > fp.close()
  > EOF
