uROSocketUtils needs some adjustments for it to work with C++Builder

Hello,

I’ve just installed the latest available build, 1593, and the uROSocketUtils unit needs some changes so the resulting header can be compiled with C++Builder:

Basically it needs to have the same {$EXTERNALSYM} directives for the consts: SD_SEND and SD_BOTH, and for the PFD_SET type as they are already for the rest of the unit.
