curl: progress bar refresh, get width using ioctl()
Get screen width from the environment variable COLUMNS first, if set. If not, use ioctl(). If nether works, assume 79. Closes #2242 The "refresh" is for the -# output when no total transfer size is known. It will now only use a single updated line even for this case: The "-=O=-" ship moves when data is transferred. The four flying "hashes" move (on a sine wave) on each refresh, independent of data.
