Fix #81252: PDO_ODBC doesn't account for SQL_NO_TOTAL

If `P->len` is negative (not only when it is `SQL_NULL_DATA`), we must
not go on, because the following code can't deal with that.

Fix #81252: PDO_ODBC doesn't account for SQL_NO_TOTAL

If `P->len` is negative (not only when it is `SQL_NULL_DATA`), we must
not go on, because the following code can't deal with that. This means
that the output parameter will be set to `NULL` without any indication
what went wrong, but it's still better than crashing.

Closes GH-7295.

Fix #44643: bound parameters ignore explicit type definitions

If `SQLDescribeParam()` fails for a parameter, we must not assume
`SQL_LONGVARCHAR` for any param which is not `PDO_PARAM_LOB`. At least
mapping `PDO_PARAM_INT` to `SQL_INTEGER` should be safe, and not
introduce a BC break.

Closes GH-6973.

Fix #80783: PDO ODBC truncates BLOB records at every 256th byte

It is not guaranteed, that the driver inserts only a single NUL byte at
the end of the buffer. Apparently, there is no way to find out the
actual data length in the buffer after calling `SQLGetData()`, so we
adjust after the next `SQLGetData()` call.

We also prevent PDO::ODBC_ATTR_ASSUME_UTF8 from fetching garbage, by
fetching all chunks with the same C type.

Closes GH-6716.

Fix #79038: PDOStatement::nextRowset() leaks column values

Firstly, we must not rely on `stmt->column_count` when freeing the
driver specific column values, but rather store the column count in
the driver data. Since the column count is a `short`, 16 bit are
sufficient, so we can store it in reserved bits of `pdo_odbc_stmt`.

Furthermore, we must not allocate new column value storage when the
statement is not executed, but rather when the column value storage has
not been allocated.

Finally, we have to introduce a driver specific `cursor_closer` to
avoid that `::closeCursor()` calls `odbc_stmt_next_rowset()` which then
frees the column value storage, because it may be still needed for
bound columns.

Remove local variables

This patch removes the so called local variables defined per
file basis for certain editors to properly show tab width, and
similar settings. These are mainly used by Vim and Emacs editors
yet with recent changes the once working definitions don't work
anymore in Vim without custom plugins or additional configuration.
Neither are these settings synced across the PHP code base.

A simpler and better approach is EditorConfig and fixing code
using some code style fixing tools in the future instead.

This patch also removes the so called modelines for Vim. Modelines
allow Vim editor specifically to set some editor configuration such as
syntax highlighting, indentation style and tab width to be set in the
first line or the last 5 lines per file basis. Since the php test
files have syntax highlighting already set in most editors properly and
EditorConfig takes care of the indentation settings, this patch removes
these as well for the Vim 6.0 and newer versions.

With the removal of local variables for certain editors such as
Emacs and Vim, the footer is also probably not needed anymore when
creating extensions using ext_skel.php script.

Additionally, Vim modelines for setting php syntax and some editor
settings has been removed from some *.phpt files. All these are
mostly not relevant for phpt files neither work properly in the
middle of the file.

Remove unused Git attributes ident

The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.

In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.

This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
