725d3fdc20 Prefer putchar over fputc where possible 
putchar is easier to understand than fputc and printf and does less work than those two do.

522f1b634f tsdump: quiet compiler warnings on some platforms. 
Quiet a -Wshadow warning from gcc.
Cast major() and minor() to unsigned int when printing.

288593875d tsdump: display both the terminal path and device number. 
If no terminal device can be found, print "major, minor" device
numbers instead.

5ff6f49653 tsdump: update to use a uid-based path by default 
This matches the changes in sudo 1.9.15 to the sudoers policy module.

14d514e5ac Avoid using %zu or %zd with printf() and fprintf(). 
This prevents problems on systems where the system printf(3) is not
C99-compliant.  We use our own snprintf() on such systems so that
is safe.

e095069d2a Prefer fputs over fprintf where possible 
fprintf does extra work and meant for formatting strings.

e343e07543 Use #include <foo.h> instead of #include "foo.h" in most cases. 
We rely on the include path to find many of these headers.  It
especially doesn't make sense to use #include "foo.h" for headers
in the top-level include directory.

22079c3072 Avoid compiler casting warnings Part 2 
This saves instructions that are related to casting as well as compiler warnings.

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.

e707ffe58b Place C23 attributes before keywords in function declarations. 
In practice this means we must use "sudo_noreturn static foo(void)"
instead of "static sudo_noreturn foo(void)".

304726a215 Move gcc-style __attribute__ macros to config.h.in 
Renamed __malloc -> sudo_malloclike, __printflike -> sudo_printflike,
__printf0like -> sudo_printf0like.
Add sudo_noreturn instead of __attribute__((__noreturn__)).
We do not use stdnoreturn.h since it has been deprecated in C23
in favor of the [[noreturn]] attribute.

bb5843055e Replace messages like "unknown foo: %s" with "unknown foo %s". 
The colon really doesn't belong there; we generally use a colon to
separate a message from the warning detail.

446ae3f507 Include string.h unconditionally and only use strings.h for strn?casecmp() 
In the pre-POSIX days BSD had strings.h, not string.h.
Now strings.h is only used for non-ANSI string functions.

dd88460800 We no longer need to include headers we don't use for sudo*.h files. 
Previously we needed to include headers required by the various
sudo*h files.  Now those files are more self-sufficient and we
should only include headers needed by code in the various .c files.

985600e7f0 Minor snprintf() usage tweaks: 
1) don't assume snprintf() returns -1 on error, check for <0
2) when comparing return value of sizeof(foo), cast the sizeof, not the len
3) cast return value to void in cases where snprintf cannot fail

ff5ac3ef0e Add tsdump, a simple utility to dump a timestamp file. To build, 
run "make tsdump" in the plugins/sudoers directory (it is not built
by default).  In order to map the tty device number to a name,
sudo_ttyname_dev() has been moved into libsudo_util.
