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.
Create where appropriate default values for the Congestion control base
values and update the derived CC values accordingly.
Move derived value #define to coap_session_internal.h.
Update coap_session_t to hold the new CC values.
Update documentation for the new CC functions that update / get the
appropriate values.
NOTE: PROBING_WAIT is not currently checked in the code.

Move coap_context_t and coap_queue_t to coap_net_internal.h.
Move internal context and queue based function definitions to
coap_net_internal.h.
Replace most references to "struct coap_context_t" with "coap_context_t".
Provide new functions to allow applications to access parts of coap_context_t
as appropriate and document these functions.
Update examples to use these new access functions where appropriate.
For the man documentation, move the server session setup functions to (new)
coap_endpoint_server(3) and update coap_context(3) with all the context access
functions as these are common to both the client and server.
Move coap_session_t and coap_addr_hash_t to coap_session_internal.h.
Move internal session based function definitions to coap_session_internal.h.
Replace most references to "struct coap_session_t" with "coap_session_t".
Provide new functions to allow applications to access parts of coap_session_t
as appropriate and document these functions.
Update examples to use these new access functions where appropriate.
For the man documentation, move the client session setup functions to (new)
coap_endpoint_client(3) and update coap_session(3) with all the session access
functions as these are common to both the client and server.
[coap_endpoint_server(3) will be created when coap_context_t is obfuscated.]
Make the old installed libcoap-2.{so,la,a,pc} libcoap-2-notls.{so,la,a,pc}, and
make the installed libcoap-2.{so,la,a,pc} be a set of soft links to installed
libcoap-2.{tlstype}.{so,la,a,pc}.
Thus installed libcoap-2.{so,la,a,pc} will be based on the latest (D)TLS
library build.
Update the linking documentation.

CoAP transaction id was formerly defined as a hash of the remote address and

message id.
Replace occurences of 'transaction id' with 'message id' to reflect naming in
RFC7252.
Correct the definition of coap_tid_t to what it actually represents.
Replace occurrences of coap_tid_t with coap_mid_t.

Update
There needs to be an easy way to validate that the examples provided in the
man pages compile without errors.
This PR provides a new executable examples-code-check that can be run against
the .txt.in files that are in the man directory. It abstracts the code for
each example and then runs the compiler against that stub code reporting errors
and warnings as appropriate for subsequent fixing in the man page.
.gitignore:
Ignore the new executable and the files it generates.
Makefile.am:
configure.ac:
Remove MAN_DIR and hard code in the man directory so that examples-code-check
is always built.
autogen.sh:
Make sure that all the temporary stub code files are cleaned up.
man/Makefile.am:
Support building and clean-up of the new examples-code-check.
man/examples-code-check.c: (new)
The code that parses the man pages, looking for examples and the gets
the examples compiled, testing for errors.
The function definitions in the SYNOPSIS section are also included in the
compilation of the examples.
scripts/build.sh:
If WITH_TESTS is set, check that the man page examples compile.
