Disable cert validation when pre-establishing connections in rlm_rest

We don't have a valid TLS configuration to use.

libcurl appears to do the right thing, and validate the cert when reconfigured to for subsequent requests.

We tell libcurl to *only* establish the connection and not send any data, so there's no chance of us
leaking sensitive information.

Remove unnecessary debug message
Move suppression of debugging messages to a better place.  Closes #772

vradlog() should always log.  It's static to log.c, so the *callers*
should take care to avoid calling vradlog().

The checks for debugging messages are pushed to radlog(), which
is the external API.

Added a static radlog_always(), which always calls vradlog().
It's just a wrapper to deal with the varargs stuff.

The vradlog_request() function now calls radlog_always(), as
vradlog_request() takes care of checking if debugging is enabled.

the references come from Cisco.
dictionary.altiga: Fix small typo & space-to-tab

Try unifying mixed usage of spaces and tabs (later seems more common)
then pass with the formatter.
