fixes for psqlodbc-07.03.20 part 2 of 2

MIND PART 1

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.: Not every question deserves an answer.
