eefb7b0d54 Use a consistent version of fuzz_conversation() with all fuzzers. 
Also undo a change to fuzz_sudoers.c that snuck in to the last commit.

7d964875df Fuzzers should not produce output. 
Excessive output makes the fuzzer runs much less efficient.

23d04dde24 iolog_nextid(): make iolog_dir argument const. 
We make a copy of the directory so there's no real reason that
parameter can't be const.

55171df5e5 Check strftime(3) return value in all cases. 
Old versions of strftime(3) didn't guarantee to NUL-terminate the buffer
so we explicitly clear the last byte of the buffer and check it.

695f4bea05 Add support for an optional offset when parsing the ID to replay. 
The offset is a suffix in the form of @sec[.nanosec]

e4568ceafe iolog_mkdtemp: umask must not be more restrictive than the file modes. 
We need this even though we will be calling mkdtemp() since the
umask affects the mode of any parent directories.

b913a832e8 Make sure we link with libsudo_util *after* libfuzzstub. 
This only affects builds with a static libsudo_util.
Also fix a warning on HP-UX about main not being public.

dfff132122 Add a new "fuzz" target that executes the fuzzers for 8192 runs each. 
To run indefinately, set FUZZ_RUNS=-1, e.g. "make FUZZ_RUNS=-1 fuzz"

95bfd65fec Flush stdout before successful return from LLVMFuzzerTestOneInput(). 
Fixes a problem with diag lines from libFuzzer being interspersed
with test output.

4c182c90f1 Rename "fuzz" makefile target to "check-fuzzer". 
It's purpose is to run the fuzzers are part of a normal "make check"
to avoid bit rot, not to perform a fuzzer run.
The fuzz_logsrvd_conf fuzzer was not wired up to "make check" previously.

9bbf120bd8 For regess/fuzz set LC_ALL to C.UTF-8 if possible, falling back on C. 
Works around a crash in leak sanitizer when the locale is set to C
and TLS support is enabled.

ea7a70e85d For "make fuzz" only fuzz the seed corpus. 
This way we avoid files generated by the fuzzer itself.

eedc72d7b9 Make fuzz targets depend on fuzzer stub library. 
We really want a dependency on $(LIB_FUZZING_ENGINE) but that could
be a flag like "-fsanitize=fuzzer" instead of a path.

53e3dca7a6 Fix up some .la file library dependencies. 
libsudo_iolog.la already depends on libsudo_util.la and libsudo_eventlog.la
so we don't need to list those explicitly when libsudo_iolog.la is listed.

bbfd430cf9 feof(3) returns non-zero at EOF, not necessarily 1. 
On Illumos at least it returns a value other than 1.

30d9497eb6 Add stub library that just feeds files to the fuzzing target. 
This will allow the fuzzers to be run as part of "make check".

4480e26972 Build (but don't run) fuzzers as part of "make check". 
Uses a stub to make it possible to link w/o libfuzzer.
The goal is to ensure the fuzzers are always buildable and avoid bit rot.
