expression evaluation.

Easter <reaster@comptechnews.com>, heavily massaged by me.  Also cleaned up
value expressions a bit.

here is the patch attached which do check in each BLOB operation, if we are
in transaction, and raise an error otherwise. This will prevent such mistakes.

(elog.c and exc.c), instead.  Modify these routines to check for a
NULL or empty-string return from strerror, too, since some platforms
define strerror to return empty string for unknown errors (what a useless
definition that is ...).  Clean up some cruft in ExcPrint while at it.

I'll leave it to the freebsders to look at that.

comment from lack of Cygwin UNIX domain socket support and to list of
current Cygwin UNIX domain socket issues.
