Update BSD service implementation (#363)

Browse source 
* Update BSD service to handle libnx's 'smart IPC buffers' for address info

* Use existing "GetBufferType0x21" for certain BSD socket methods

* Parse address port as unsigned short

* Fix bounds check on reading the IPC buffer

* Implement Read, Write methods

* rebased and cleaned

* addressed nits

* remove unused swap method

* fixed alignments
