Add new event types to report the TCP connection status and CSM exchange
status to the application. Add optional auto send of ping messages for
reliable client sessions. Add default timeout of 30s for receiving a CSM
message from the remote host after connect.

New struct coap_binary_t - same as coap_string_t, used for tokens
Deprecate struct str with the intent of removing it downstream as it
polutes namespace.
Make end of coap_string_t data a NUL.
Updated coap_make_str_const(), removing .length= and .s= to keep upstream
compilers happy.
Update Doxygen for str.h

Update
Add in -d max option, which then causes coap_resource_unknown_init() to get
called.
Number of dynamic resoures is limited by 'max'. The current set of resources
can be determined by using .well-known/core
If max is reached, 4.06 is returned.
Fixed typo in man coap_resource(3) in example for unknown resources
Updated to support the new coap_dtls_pki_t.
Add in new -C and -R options to support / test PKI mutual authentication
Make sure time resource is triggered no more frequently than once a sec.
coap_show_pdu()'s API is now coap_show_pdu(coap_log_t, coap_pdu_t*)
New function void coap_set_show_pdu_output(int use_fprintf)
Default is use fprintf() instead of coap_log()
The output buffer size can be configuring -DCOAP_DEBUG_BUF_SIZE
Output COAP_OPTION_SIZE2 option as well
For binary data, output ascii readable equivalent immediately under the
hex output for ease of debugging.

To document that uri.port input to coap_encode_var_safe() never
has more than 16 bits, an explicit bit mask has been added. This
change is supposed to avoid the false positive CID 1469635.
cmdline_content_type() treated option numbers as 8-bit integers and
therefore could not parse values >255. Now, option numbers are
represented as uint16_t to allow for numbers between 0 and 65535.
Moreover, as RFC 7252 has made the Accept option non-repeatable,
cmdline_content_type() now will only add a single Accept option.
Calling strncpy() on the variable (and erroneous) calculated token
length in cmdline_token() has caused stringop-overflow warning by
GCC 8. This change fixes the error and replaces strncpy() by
memcpy() to quieten the compiler.
Update code / examples / man pages with the updated function.
include/coap/libcoap.h:
Add in new define COAP_DEPRECATED to generate compiler warnings when used
include/coap/encode.h
New coap_encode_var_safe() function that includes the size of the output
buffer as a parameter.
Make coap_encode_var_bytes() a wrapper for coap_encode_var_safe() and
mark it as COAP_DEPRECATED for backwards compatability

New coap_encode_var_safe() function that includes the size of the output
buffer as a parameter.
examples/coap-server.c:
examples/contiki/server.c:
Make the ticks resource consistent in case
The function is not used because most of the timer handling has
been moved to coap_run_once().
This change avoids clang to emit a warning due to -Wunused-function.
coap_add_optlist_pdu() sorted the options for insertion, but did not update
the coap_optlist_t head (whch may then no longer point to the first entry in the
sorted chain) and so when coap_delete_optlist() was called, the first few
entries of the sorted chain may not get deleted.
Fixed by making it
coap_add_optlist_pdu(coap_pdu_t *pdu, coap_optlist_t** optlist_chain)
instead of
coap_add_optlist_pdu(coap_pdu_t *pdu, coap_optlist_t* optlist_chain)
Additionally deleted options_start() and options_next() as they are not
required - Issue #184.

As discussed in bug #185 [1], const strings should be protected
from being overwritten. This change adds -Wwrite-strings to the
compiler warning flags and fixes resulting warnings by making
static strings const.

The input value for time in hnd_put_time() is not sanity checked for the
upper limit. If too large, gmtime() etc. functions will return a failure
(errno is EOVERFLOW).
Validate the input value to hnd_put_time(). Return 4.00 if failure
Verify return from gmtime() in hnd_get_time() before trying to convert to
ascii readable string. Return 4.04 if failure.
[Time may just be valid when updated in hnd_put_time(), but then
increments to be too large - hence check also in hnd_get_time()]

Remove coap_list_t structure and replace with coap_optlist_t to maintain
backward code compatability.
Make use of the new coap_optlist_* functions
Use the new coap_optlist_t structure
Remove unneeded header includes
warn() -> coap_log(LOG_WARNING, )
debug() -> coap_log(LOG_DEBUG, )
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.
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.
Make coap_pdu-t independent of the header style.
Use C99 sized types when applicable.
Use transaction ids in host byte order in the library.
Make coap_pdu_t payload storage grow on demand.
Add parsing and encoding of PDUs with UDP or TCP style headers.
Adapt examples and unit tests to the new PDU format.
