e54ba33ea0 Avoid compiler casting warnings by assigning to the same type where possible
This saves instructions that are related to casting as well as compiler warnings.

2845ceafb0 Handle "locale -a" returning both C.UTF-8 and C.utf8.
It is possible to have mutiple matches from the output of "locale
-a".  Just take the first one.  Fixes GitHub issue #241.

334daf92b3 Escape control characters in log messages and "sudoreplay -l" output.
The log message contains user-controlled strings that could include
things like terminal control characters.  Space characters in the
command path are now also escaped.

Command line arguments that contain spaces are surrounded with
single quotes and any literal single quote or backslash characters
are escaped with a backslash.  This makes it possible to distinguish
multiple command line arguments from a single argument that contains
spaces.

If we cannot remove the directory tree that may indicate a file or

5683fc6f7a The name of the C locale w/ UTF-8 support is not always C.UTF-8.
Use a pattern to find it (if present) and use that value instead
of hard-coding C.UTF-8.  This works around a leak sanitizer crash
on certain inputs.

b19bd98531 iolog_pwfilt_run: apply regex on ttyout even if we disabled filtering.
The heuristic used to decide when to disable filtering is when we
see another ttyout buffer or find a cr or nl in the ttyin buffer.
However, we should also check the buffer that caused us to disable
filtering for a matching regex that would re-enable filtering.
Programs that prompt for a password twice might otherwise not have
the second password filtered.
