Added ssize_t to configure code.

Got 'religion' about using size_t and ssize_t for read/write stuff
as part of the code to expose 64 bits to the client.

This checkin does all the 'easy' stuff - such as all the read/write/lock
calls - but now comes the harder parts (open & friends) and all the
file enquiry functions.....

Jeremy.
