Add new function coap_package_build() which returns "git describe --tags"
if available at library build time, else standard package version.
The value of "git describe --tags" is created at run time and passed in as
a compiler -D definition.
Update copyright end dates for updated files.
doc/module_api_wrap.h: New
Used to split modules into Application and Internal only.
include/coap/*.h:
Module (@defgroup) description put into group application_api or internal_api
as appropriate.
Add in @file information if missing.
src/*.c
Add in @file information.
The syslog LOG_ definitions are defined in <syslog.h> and can be defined in
coap_debug.h (wrapped by a HAVE_SYSLOG_H wrapper to prevent duplicaton).
However, the coding order of
include <coap3/coap.h>
include <stdio.h
works, but
include <stdio.h
include <coap3/coap.h>
but fails if the application build environment does not define HAVE_SYSLOG_H
(as is the case of the examples in the examples/ directory).
The former "just" happens to work as the values of the variables are the same.
This fix is to remove the coap_log_t enum and replace it by simple #define
if LOG_ALERT etc. is not already defined.
Make coap_log_t int to remove Visual Studio compile warnings.
