Test whether an engine opened successfully

[GoogleCodeExporter]

Hi Arsen,

I came across an issue related to engine-specific parameters you introduced
in r1079 -- many thanks. If a plugin needs some parameters from config, it
must be initialized in mrcp_engine_virtual_open(), not in
mrcp_plugin_create(). But the server does not care whether the
initialization was successful or not. You should check the return value in
mrcp_server.c:632.

Thanks.

Hi Vali,
I completely agree, return value must be checked and I'll have closer look at 
this
issue hopefully soon.
Thanks,
Arsen.

Hi Vali,
I addressed this issue in r1125, but seemed to forget update the status here.
Briefly, I added internal state to engine (is_open), which indicates whether 
engine
has been successfully opened or not. In any case engine remains in the table, 
but
will not be used if open method fails.
