c131b27474 For 'make check-verbose' run fuzzers with -verbose=1 
This is the default for libFuzzer but not for the stub fuzzer lib.

cadfbfedb9 Add tests for iolog filtering. 
This is the functionality used by the log_passwords and passprompt_regex
options.

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.

6564f1ae4c Work around a glibc regcomp() bug with repeated '+' operators. 
Glibc regcomp() has a bug where it uses excessive memory for repeated
'+' ops.  Collapse them to avoid running the fuzzer out of memory.

946404434e lib/iolog: add support for filtering password out of tty input 
If a password regex is found in the tty output, tty input will be
replaced with '*' chars until a newline or another tty output
character is received.

a554629d84 Flush I/O logs before we send a commit point. 
The commit point message means we have written the data to disk so
we should not be buffering it any longer.
We do not currently fsync(2) the data after flushing, perhaps we should.

23d04dde24 iolog_nextid(): make iolog_dir argument const.

parameter can't be const.

so we explicitly clear the last byte of the buffer and check it.

e4568ceafe iolog_mkdtemp: umask must not be more restrictive than the file modes.

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.
