Patch for bug's in SocketPort and IOException

[Prochnow, Christian]

Hi List,

found some problems in recently added features:

in IOException::getSystemErrorString():
- _systemErrorString must only be allocated once.

- i thought "if ( NULL == _systemErrorString )" was not the intention of the 
programmer, instead it should be "if ( NULL != _systemErrorString )"

- in IOException::~IOException():
delete _systemErrorString - simply not right - array`s are deleted with
delete[] not with delete.

SocketPort connecting constructor:
- do not restore the O_NDLAY flag when ::connect() has failed!
 this caused the connectError() to store a zero error code cause the fcntl() 
after connect() succeeded :)

Regards,
Christian
