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.

cc22cca34f Add an fd argument to sudo_get_ttysize() instead of always using stderr.
For sudoreplay we open /dev/tty, so use that instead of stderr when
determining the terminal size.

2d9c0d9034 Add eventlog_store_sudo() and use it in sudoreplay.
This replaces the custom log formatting used by "sudoreplay -l".

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.

1f58e5a8e0 Fix IS_IDLOG macro, it was testing the wrong byte for the NUL.
This causes the macro to evaluate to false even for valid TSIDs.

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.

4e4b506f22 Sync "sudo -l" output with normal sudo log format.
It now prints runchroot and runcwd (falling back on cwd).
As a result, submithost is now printed first, matching sudo.
Also avoid printing NULL pointers and skip entries that don't have
at least command, submituser and runuser set.

70aef0eb2d sudo_debug_register: add minfd argument to specify lowest fd number

fd which the shell reserves for use by scripts.

cbad17a994 Move inclusion of compat headers up with the system headers.
Now that sudo_dso_public is defined in config.h we don't need sudo_compat.h

452be1a4c5 Add a follow option (-F) to support replaying a live session.
By default, sudoreplay will exit when it reaches the end of the
timing file.  With the -F option, it will keep going until the
timing file is finished and its write bit is cleared.

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

a71eb86a71 Add new -S option to sleep while the command was suspended.

e318f27fba When parsing an I/O log timing line, store the result in a timespec,
not a double.  The speed factor (for scaling the delay) in sudoreplay
is still a double but we only need to adjust the delay if the factor
is something other than 1.0.

04d1f56d90 Use struct timespec, not struct timeval in the event subsystem.
