Jon Shallow 3897d2334c Logging: Make logging consistent across (D)TLS libraries ...

Set up coap_log_t as an enum, using syslog variable names prefixed by
COAP_.

Add function coap_dtls_log() for logging information from (D)TLS libraries.

Update the log output to have use Lower-case variants for the logging levels to
indicate that output is from the (D)TLS library instead of the CoAP library.

(D)TLS libraries updated to be consistent in the usage of
coap_dtls_set_log_level()/coap_dtls_get_log_level().

Add in coap_log_emerg(), coap_log_alert() etc. as wrappers to reduce the line
length required for log entries.  Updating all the coap_log() functions to
no longer use syslog variants will be a part of a separate PR.

Added in the "-V" option to the examples, with an initial default of
COAP_LOG_ERR, separating out the CoAP and (D)TLS logging levels.

Note: TinyDTLS log output will be consistent when built against a TinyDTLS
version that contains support for an external logging handler.
