tds: Prevent infinite loop when sending disconnect request

For TDS 5 (Sybase) connections, a disconnect request is sent
    automatically during disconnect.

If the request cannot be sent, the disconnect logic may retry the
    disconnect operation, causing another disconnect request to be sent.
    This can lead to an infinite loop of failed disconnect requests.

Fix compatibility with Nettle 4 library

Hash length parameter was removed from digest functions like
    nettle_md4_digest and sha1_digest.

Change similar to commit e2bf8f3a3e81f1aa94fd15fa206dd4ec5ddf2ec7
    (cfr "utils: Fix compatibility with Nettle 4 library").

odbc: Make SQLSetDescField extend automatically the descriptor

This it's the correct behaviour for SQLSetDescField, not
    returning error if the record is missing.

odbc: Fix SQL_DESC_BIND_OFFSET_PTR handling

Use sql_desc_bind_offset_ptr not only on structure binding or
    on following (not first) rows.
    SQLExtendedFetch uses sql_desc_bind_offset_ptr so do not clear it.
    Add a test, partially from Bob Kline.
    This fixes https://github.com/FreeTDS/freetds/issues/716.

odbc: Fix leak in SQLDriverConnect if string is invalid

Login structure was not freed if odbc_parse_connect_string
    returned false, which can simply happen if the string has
    an invalid syntax.

tds: Avoid overflow converting numeric to string

Author: Aaron M. Ucko <ucko@ncbi.nlm.nih.gov>
Date:   Thu May 9 16:36:31 2024 -0400

Improve support for TDS 5 (Sybase) bulk transfers.

* Read defaults, send them back explicitly as needed, and clean up
      their storage afterwards.
    * tds5_bcp_add_variable_columns:
    ** Send spaces in lieu of fully empty SYB(VAR)CHAR data.
    ** Send correct textpos values in all cases.
    ** When writing the adjustment table, avoid a potential Sybase "row
       format error" by eliding the (effective) column count when it would
       have repeated the largest adjustment table entry.
    * tds_deinit_bcpinfo: Free and reset current_row for transfers in.
      Avoid potentially trying to interpret fragments of outgoing TDS
      data as BLOB pointers.

odbc: Fix for SQL_COPT_SS_OLDPWD attribute

This attribute allows to change the password while logging
    to the server.
    Code was wrongly taking the length of the attribute in
    characters instead of bytes causing a failure using wide
    function.

Fix ABI breakage for tdsdump_open under Windows

tdsdump_open is exported by our DB-Library implementation.
    Before version 1.5 tdsdump_open always accepted a "const char*"
    string, however in 1.5 this was changed to "const wchar_t*" for
    Windows to support Unicode.
    This broke ABI for Windows.
    Provide tdsdump_open with old ABI and a new tdsdump_wopen
    (Windows only).

odbc: Accept any variable data type using DATA_AT_EXEC length

Reported in https://github.com/FreeTDS/freetds/issues/667.

The behaviour is consistent with Microsoft driver.

This caused an issue using PHP ODBC PDO driver.

Use CORK flag correctly, do not delay partial packets

Resetting TCP_CORK flag in Linux causes the partial packets
    to be flushed however if the queue is full partial packets
    are not moved to the queue.
    Partial packets are then processed when space is available.
    However FreeTDS used to set again the flag causing partial
    packets to be delayed.
    Remove that delay reducing latency.

          |                                       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
          |                                                                                    |

long should be enough for 49 days in case of 32 bit, I hope
    your query doesn't take so long.
