I'm sending new version of patch.

I've replaced readonly option with target_server_type (with JDBC
compatibility alias targetServerType), 

use logic of setting defaults based on number of hosts in the connect
string instead of complicated condition in the state machine,

added checks for return values of memory allocation function.

Also, I've solved pg_usleep problem by linking pgsleep.c into libpq
along with some other libpgport objects which are already linked there.

Thus client applications don't need to link with libpgport and libpq
shared library is self-containted.
