backport type change for parse.y
Don't declare variables as "unsigned char *" that are passed to functions that take "char *" arguments. Where such chars are assigned to int or passed to ctype functions, explicitly cast them to unsigned char. For OpenBSD' clang, -Wpointer-sign has been disabled by default, but when the parse.y code was built elsewhere, the compiler would complain. (originally by naddy@ for various parse.y in the tree)
s/SIMPLEQ_/STAILQ_/g
STAILQ_* macros seems to be more widespread than SIMPLEQ_*
add flags to listener; warn if missing auth_table
in the future we'll have also plain 9p, so mark the tls listeners with L_TLS and add the libtls machinery only in that case.
avoid redefining symbol `listen'
on some version of bison there's an issue since we have a rule `listen' and a variable `listen'.
