Daniel Rosenberg aea95681c2 Fix diff between symlinks and fifos 
diff should allow comparison between regular files and fifos
Added a few tests to help catch regressions here, and added
some cleanup for files the test creates.

Elliott Hughes 85a4098424 diff.test: mksh compatibility. 
This test never passed on Android, but a quirk of how we were running
it meant we never noticed before.

James Farrell 7ab529557d Handle diffing FIFOs. 
Also exit immediately if a seek fails.

In addition to the supplied test, also tested manually with:

./toybox diff <(echo -e "1\n2") <(echo -e "1\n3")

However, the "testing" function in runtest.sh doesn't handle such
syntax.

James Farrell 9f5fb9ae9a Diff line format options. 
--unchanged-line-format
--old-line-format
--new-line-format

We want to use Toybox to make AOSP builds closer to hermetic, and these
flags are used here:

Elliott Hughes 36b1b7d1f8 diff: implement --strip-trailing-cr. 
Used by some ART tests and also some LLVM tests. (The motivating example
is the latter, but I noticed the former when looking for other users.)

Elliott Hughes b1562a6fda diff: use TOYFLAG_ARGFAIL. 
This one with a little cleanup of unnecessary duplication.

Elliott Hughes 4d673c9ad4 diff: add timestamps to the ---/+++ lines and --color. 
(My apologies for mixing these two unrelated changes up.)

Andy Chu 433296f880 Fix a buffer overflow in diff -r. 
We were doing two 32-byte memset()s instead of two 16-byte memset()s.
'dir' referred to the instance (array of 2) and not the struct type.

Add some test coverage for diff, including a case that hit this bug.

The bug was found by running cp.test under AddressSanitizer, since it
happens to use diff.
