This makes the receive path to only execute in context of the receive thread
and allows for further simplification.

When syslogd forks a process for '|' destinations, it closes all file
descriptors greater than 2.
Use closefrom() for this instead of a getdtablesize()/close() loop because
it is both faster and avoids leaving file descriptors open because the limit
was lowered after they were opened.

X11 side of things from bleeding into Xdialog(1) stderr output). It should
be duely noted that such errors are not a by-product of anything in the
Xdialog(1) utility or API, but optional libraries that it can link against
(such as Gtk1 versus Gtk2; if you compile xdialog from ports against Gtk2
AND misconfigure your fonts or generally make Gtk2 unhappy, these warning
messages can bleed into the captured stderr -- that is we we sanitize!).

by ~30-40% and doesn't harm req/resp time for stock netperf runs.
Future work will use a thread pool rather than a thread per tx queue.

Also, fix local variable names where necessary while we're here with
other minor comment-enhancements/typo-corrections.
improve debugging initialization. Also fixup USAGE statements while we're

This compiler flag enforces that that people either mark variables
static or use an external declarations for the variable, similar to how
-Wmissing-prototypes works for functions.
Due to the fact that Yacc/Lex generate code that cannot trivially be
changed to not warn because of this (lots of yy* variables), add a
NO_WMISSING_VARIABLE_DECLARATIONS that can be used to turn off this
specific compiler warning.
