The JSON API restart in stop() cost a RESTART_BURST_PROTECTION wait (7s) on
every exit and brought the HTTP server back up in the middle of the core
teardown, republishing resources whose backing services were about to stop.
It was not gratuitous: it made "delete mJsonApiProvider" safe, because the
running restbed service holds the resources this provider returned and their
handlers capture it. libretroshare now stops the JSON API at the top of
rsGlobalShutDown(), before stopPlugins(), so the resources are already gone
by the time stop() runs and the provider can be deleted directly. Without
that companion change this commit would turn a slow shutdown into a
use-after-free, so the two go together.
Also replace the five std::cerr traces with one RsDbg line on success and an
RsInfo when the JSON API is not available, matching how the rest of the tree
reports.
Avoid the need of dirty patching to set the version at build time
In case RS version is not passed as argument attempt to determine it
using git describe, if unavailable use hardcoded default
Moved header file with version information to retroshare/rsversion.h.
Added version information to Windows executable.
