Single shared Watcher used to avoid inotify limit

Benoit Sigoure f69ef84e36 Fix race in the detection of truncation. 
Before going into ChangeEvents(), the code was calling stat on the file
to know where it was at, which is incorrect as stat could return the new
file size post truncation.  Instead we now ask the file descriptor about
our current offset, so we can compare our offset to the file size to try
to detect truncation.

Truncation detection remains brittle, but this closes an annoying race
we frequently run into.

Sridhar Ratnakumar 929590016a use ReadString instead of ReadLine 
ReadLine is a low-level primitive, and we don't do a good job of
splitting the lines as they are being read. best to read the entire
line and then split it in one go.

with this change, there is one test failure that will be resolved
next:

  --- FAIL: TestMaxLineSize (0.10 seconds)
