Repair "tcp server queue overflow" brokenness, more <stdbool.h> fallout.

Return value of mbuf_len() wrong - it's returning a length value, not
a yes/no value - so when the queue length approached 65 (full!), it
still only returned "1", leading to MBUF overflow later on.  Change
from "bool" to "unsigned int", misbehaviour gone...

This fixes OpenVPN trac ticket #263.

Fix parameter listing in non-debug builds at verb 4

When built with enable_debug=no, the parameter output expected at --verb
4 is not printed due to use of #ifdef ENABLE_DEBUG in the responsible
code sections. This appears to be a mistake when looking at the
configure help text for enable_small and enable_debug.

This change keys the relevant code off of enable_small instead,
including the parameter listing when enale_small=no (the
configure-script default.) Most of this code is in options.c, with some
callers present in plugin.c/h and route.c/h. No function code is
changed, just the #ifdef values to use the small feature instead of
debug.

This means builds no longer need enable_debug=yes in order to get the
expected log output at verb 4.

(updated) [PATCH] Warn when using verb levels >=7 without debug

This text change makes sense: I've adjusted it to read "NOTE: debug
verbosity..." and saved another byte removing the comma.

Updated patch attached.

Subject: [PATCH] Warn when using verb levels >=7 without debug

This patch adds a log warning when using --verb levels at 7 or higher
when running on builds lacking debug support. Since official builds are
now built with enable_debug=no, this warning will help developers
identify why expected debug messages may not be present in log output.

The test and message output code is omitted when built with
enable_debug=yes or enable_small=yes.

PolarSSL-1.2 support

Add support for PolarSSL-1.2, which has changed the API in several places.
This is a minimal port, new features have not been enabled. Only PolarSSL
1.2.5 and newer are accepted, as earlier versions contain unresolved
(security) issues.

Config compatibility patch. Added translate_cipher_name.

Added translate_cipher name to crypto_openssl.c and crypto_polarssl.c
to translate between OpenVPN(/OpenSSL) and PolarSSL data channel
cipher algorithm names. OpenSSL does not require any translating,
PolarSSL does for a small number of algorithms. This improves on
config file compatibility between the OpenSSL and PolarSSL builds.

Fix directly connected routes for "topology subnet" on Solaris.

This basically brings back the previously-working metric setting for
directly connected routes (add a "0" to the "route add" command) on
Solaris/OpenSolaris.  It was working in f0eac1a59790, and got broken
by the route.c/route.h refactoring in 576dc96ca1ef1 - the patch
un-does that change to the TARGET_SOLARIS code, plus adds some more
descriptive comments.
