Upgrade to VS2017. Added a property sheet with user variables to configure the
target installation directory and location of openssl library from within the
Visual Studio GUI and in a manner compatible with msbuild. This method is
inspired by the GTK project. It supports out of tree builds, and separate or
common directories for debug and release builds. The new install project copies
the library files to the selected target directory. It has all other projects
in dependency, so to build the library and utilities, you just build the
"install" target and it will take care of building the library, executable,
then copy to a tree with a unix-like structure (bin, lib, include).
Also fixes missing files in the testdriver project.
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.
Merge changes from PR #47 related to windows platform support.
Add full windows platform support including correct error checking and working regression tests and examples.
Remove need to build applications using libcoap with -DWITH_POSIX and to include coap_config.h. This applies to the examples as well.
