syslog support; bitwise logior and logand functions become variadic.

* Makefile: Use -iquote to restrict our #include search paths from being
processed for #include <...>.  Add syslog.o to OBJS-y if have_syslog is y.

* configure (have_syslog): New variable, set by detecting syslog API.

* eval.c (eval_init): logand and logior registrations changed to
go to variadic versions. New syslog variables and functions registered.

* lib.c (logandv, logiorv): New functions.

* lib.h (logandv, logiorv): Declared.

* txr.c (main): Call syslog_init.

* syslog.c: New file.

* syslog.h: New file.
