allow newlines in table syntax

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)

fix parse table bug: now <users> correctly refers to the table

add a mean to debug yylex

s/SIMPLEQ_/STAILQ_/g STAILQ_* macros seems to be more widespread than SIMPLEQ_*

error also if `tls pki' is missing

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'.

don't require strict ordering in listen + table misc
