Problem: xxd: no color support
Solution: Add color support using xxd -R
Add some basic color support for xxd
The hex-value and value are both colored with the same color depending
on the hex-value, e.g.:
0x00 = white
0xff = blue
printable = green
non-printable = red
tabs and linebreaks = yellow
Each character needs 11 more bytes to contain color. (Same color in a
row could contain only one overhead but the logic how xxd creates colums
must be then changed.) Size of colored output is increased by factor of
~6. Also grepping the output will break when colors is used.
Flag for color is "-R", because less uses "-R".
Color uses parameters auto,always,never same as less and grep (among
others).
E.g.
xxd -R always $FILE | less -R
Add some screen-tests (that currently on work on linux) to verify the
feature works as expected.

Problem: Terminal test for current directory not used on FreeBSD.
Solution: Make it work on FreeBSD. (Ozaki Kiichi, closes#9516) Add
TermWait() inside Run_shell_in_terminal() as a generic solution.
Problem: Test sometimes fails waiting for shell in terminal.
Solution: Use WaitForAssert() so we can see the actual job status. Use
Run_shell_in_terminal().
Problem: Some terminals misinterpret the code for getting cursor style.
Solution: Send a sequence to the terminal and check the result. (IWAMOTO
Kouichi, closes#2126) Merged with current code.
Problem: Tests using term_wait() can still be flaky.
Solution: Increase the wait time when rerunning a test. (James McCoy,
closes#5899) Halve the initial times to make tests run faster
when there is no rerun.
Problem: When testing in the GUI may try to run gvim in a terminal.
Solution: Add the -v argument. (Yee Cheng Chin, closes#4605) Don't skip
tests that work now.
