Update functions appropriately.
Move coap_new_client_session_pki() back into coap_session.h (its correct place)
Add in enum coap_asn1_privatekey_type_t
A simple structure for (D)TLS-specific unit tests has been added.
Currently, only general support and the version number as reported
by coap_get_tls_library_version() are checked.
As unit tests with IPv6 addresses keep failing on docker-based
travis CI, this changes reverts to IPv4 usage in following files:
test_wellknown.c
test_sendqueue.c
Update coap_context_set_psk() to return on failure. Add in call to
coap_dtls_context_set_psk() function
Add in new function coap_context_set_pki()
Update #includes for compilation
Update coap_new_client_session_psk() to clean up and return on error. Add in
call to coap_dtls_context_set_psk()
Add in new function coap_new_client_session_pki()
Additional check for a call of coap_new_client_session_*() in
coap_new_endpoint()
Remove PSK specifics from coap_dtls_new_context() and put into new
coap_dtls_context_set_psk().
Create a new coap_dtls_context_set_pki() for PKI.
Include checks that either of coap_dtls_context_set_psk() or
coap_dtls_context_set_pki() have been called before setting up a (D)TLS
session
Update #includes for compilation
Add in coap_get_tls_library_version() for determining TLS build base + version
Do not allow a dynamic openssl library to be loaded and used at application
runtime that is less than OpenSSL version 1.1.0.
A new function coap_get_tls_library_version() that returns a pointer to a
coap_tls_version_t structure that contains both the TLS library type libcoap
was compiled against as well as the current TLS library version.
John Carter has provided this (slightly edited) patch to set len to 0
for PDUs that do not contain a payload. This makes this function more
robust for callers that do not care about the function result.
This change fixes issue 120 [1].

The dead code detected by Coverity scan in CID 1458395 has been
replaced with explicitly setting the return value to 1 (the default
that has previously been used).
As coap_send() automatically releases the specified pdu, it must
not be accessed after coap_send() has returned.
This change fixes CID 1458399 reported by Coverity scan.
coap_send() always takes the ownership of the pdu that is passed
as argument to send, i.e., the memory will be released automatically
when the pdu is not needed anymore.
In CID 1459612, Coverity scan has complained about uninitialized use
of the variable bytes_read. Although this is a false positive here,
it seems to be more safe to always initialize bytes_read.
In coap_session_create_client(), the default port for TCP did not
correctly distinguish between TCP and TLS as pointed out in [1] by
Joan Shallow. This change applies the suggested fix.

The value of the observe option is kept for each resource rather than being global to the context.
The value of the observe option must wrap to be stay below 2^24.
The value of the observe option must be different from the initial value when a notification is sent.
