Paul E. McKenney 5d43edb407 rcutorture: Check for self-detected stalls
The current scripts parse console output only for cases where one CPU
detect a stall on some other CPU or task.  This commit therefore adds
checks for self-detected stalls.

Paul E. McKenney fc91cbab11 rcutorture: Don't keep empty console.log.diags files
Currently, an error-free run produces an empty console.log.diags file.
This can be annoying when using "vi */console.log.diags" to see a full
summary of the errors.  This commit therefore removes any empty files
during the analysis process.

Paul E. McKenney 5708c64757 torture: Abbreviate console error dump
Currently, the scripts print a list of warning/bug indicators from the
console.log file.  This works well if there are only a few warnings or
bugs, but can be quite annoying if there is a large number.  This commit
therefore prints a summary listing the number of each type of warning/bug
indicator, but only if there is at least one such indicator.  The full
list is stored in the results directory at console.log.diags, which
makes it easier to find the warning/bugs in the full console.log.

Paul E. McKenney e9408e4f27 rcutorture: Add checks for stall ending before dump start
The current rcutorture scripting checks for actual stalls (via the "Call
Trace:" check), but fails to spot the case where a stall ends just as it
is being detected.  This commit therefore adds a check for this case.

Paul E. McKenney bc51896da2 torture: Check for nul bytes in console output
When starting a new torture run while an old one is still running, both
qemu processes can be outputting to the same console.out file.  This can
cause quite a bit of confusion, so this commit checks for this situation,
which is normally indicated by nul bytes in the console output.  Yes,
if your new run uses up an exact number of blocks of the file, this
check will be ineffective, but the odds are not bad.

Pranith Kumar 3327d924a7 rcutorture: Set executable bit and drop bash from Usage
This commit sets the executable bit on test scripts config2frag.sh
and kvm.sh.  Since #!/bin/bash is set in all the scripts, this commit
also drops it from all usage lines because the scripts can now all be
invoked directly.

Pranith Kumar 1a5e31fbf9 rcutorture: Use bash shell for all the test scripts
Some of the scripts encode a default /bin/sh shell. On systems which use
dash as default shell, these scripts fail as they are bash scripts. I
encountered this while testing the sprintf() changes on a Debian system
where dash is the default shell.

This commit changes all such uses to use bash explicitly.

Paul E. McKenney 0e342a87d5 rcutorture: Stop tracking FSF's postal address
All of the rcutorture scripts has the usual GPL header, which contains
a long-obsolete postal address for FSF.  To avoid the need to track the
FSF office's movements, this commit substitutes the URL where GPL may
be found.

Paul E. McKenney 6d40cc0cb4 rcutorture: Flag errors and warnings with color coding
The output of the rcutorture scripts often requires interpretation, so
this commit simplifies this interpretation by tagging messages as
BUGs (colored red) or WARNINGs (colored yellow).
