fixes for psqlodbc-07.03.200 part 1 of 2

MIND PART 2

Here are my updates/fixes for version 07.03.200.
Details:
- EINTR safety for send/recv, NOT4WIN
- init vars before using them (most prominently in
  dlg_specific.c::SQLGetPrivateProfileString calls),
- avoid those notorious core dumps when logging on hitting
  "null" data... in result.c
- make 07.03.200 work with the new mutex_locks
- may use -DHAVE_ECO_THREAD_LOCKS, if you use libiodbc (or similar)
  which already shells every driver call in mutex_locks
- using the driver (in conjunction w/libiodbc) on Solaris in a
  threaded environment (thus --enable-pthreads) we also found that
  -DHAVE_LOCALTIME_R is a good idea, also configure does not auto-
  link libsocket which is needed anyway... (mind libnsl when not
  threaded)

please also read included README (which is a HISTORY as well)

P.S.: Always do right. This will gratify some people, and astonish the rest.
        - Mark Twain (1835-1910)
