Fix `serverURIs` iterating in MQTTAsync.c

This commit fixes two bugs related to `serverURIs` iterating in MQTTAsync.c

1. Segfault occurs when there is no healthy connection in `serverURIs`

   Two off-by-one errors of the `currentURI` cause the issue. The first
   one happens when doing boundary check of `serverURIs`, and the other
   one happens when accessing `serverURIs` without checking the boundary
   first.

2. The first URI in `serverURIs` gets skipped when restricting
   `MQTTVersion` to a particular value

   `currentURI` gets increased *before* connection attempts in each
   iteration.

Updates the RPM packaging makefile

Replaces the build directory with the build.paho directory in the RPM
source tarball creation, otherwise the tarball may contain locally
generated files and fail to properly build the RPM package.

Proposal for non-SSL version error. Issue #251

Compile static ssl libraries with OPENSSL=1

Extend the willOptions initializer to include the new binary payload fields

Merge branch 'testcase-for-issue-190-without-serverURI' of https://github.com/JuergenKosel/paho.mqtt.c into fixes

Non-SSL version of the library report an error if the caller requests an SSL connection. Possible soluiton for Issue #251

Explicitly enable OPENSSL=1 for the static ssl enabled libraries.
Otherwise a linker error is generated when using the libraries.
