94dec9114b Modify libpq's string-escaping routines to be aware of encoding considerations 
and standard_conforming_strings.  The encoding changes are needed for proper
escaping in multibyte encodings, as per the SQL-injection vulnerabilities
noted in CVE-2006-2313 and CVE-2006-2314.  Concurrent fixes are being applied
to the server to ensure that it rejects queries that may have been corrupted
by attempted SQL injection, but this merely guarantees that unpatched clients
will fail rather than allow injection.  An actual fix requires changing the
client-side code.  While at it we have also fixed these routines to understand
about standard_conforming_strings, so that the upcoming changeover to SQL-spec
string syntax can be somewhat transparent to client code.

Since the existing API of PQescapeString and PQescapeBytea provides no way to
inform them which settings are in use, these functions are now deprecated in
favor of new functions PQescapeStringConn and PQescapeByteaConn.  The new
functions take the PGconn to which the string will be sent as an additional
parameter, and look inside the connection structure to determine what to do.
So as to provide some functionality for clients using the old functions,
libpq stores the latest encoding and standard_conforming_strings values
received from the backend in static variables, and the old functions consult
these variables.  This will work reliably in clients using only one Postgres
connection at a time, or even multiple connections if they all use the same
encoding and string syntax settings; which should cover many practical
scenarios.

Clients that use homebrew escaping methods, such as PHP's addslashes()
function or even hardwired regexp substitution, will require extra effort
to fix :-(.  It is strongly recommended that such code be replaced by use of
PQescapeStringConn/PQescapeByteaConn if at all feasible.

8f7fce2fd6 Fix ancient memory leak in PQprintTuples(); our code no longer uses this 
routine, but perhaps some applications do.  Found by Martijn van Oosterhout

8372956243 When using GCC on AMD64 and PPC, ECPGget_variable() takes a va_list *, not 
a va_list. Christof Petig's previous patch made this change, but neglected
to update ecpglib/descriptor.c, resulting in a compiler warning (and a
likely runtime crash) on AMD64 and PPC.

are inconsistent with the rest of the .po files, and apparently cause
problems for Sun's cc. Per report on IRC from "bitvector2".

8416036f5f Kerberos fixes from Magnus Hagander --- in theory Kerberos 5 auth 
should work on Windows now.  Also, rename set_noblock to pg_set_noblock;
since it is included in libpq, the former name polluted application
namespace.
