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 superfluous variable

Require SQLite ≥ 3.7.4 for ext/sqlite3

`SQLite3::readOnly()` uses `sqlite3_stmt_readonly()` which is only
available as of libsqlite 3.7.4. For older SQLite3 versions we return
always `false`, which can be confusing. Instead of sticking with this
behavior, or even undefining the method for old SQLite3 versions, we
lift the requirements to SQLite 3.7.4 (released on 2010-12-08),
according to a respective discussion[1].

Since pdo_sqlite doesn't use `sqlite3_stmt_readonly()`, we stick with
the minimum requirement of SQLite 3.5.0.

Require SQLite ≥ 3.5.0 for ext/sqlite3 and ext/pdo_sqlite

It is possible to pass flags when opening an SQLite database. For
Sqlite < 3.5.0 these are ignored, since `sqlite3_open` doesn't support
flags. Neither a warning or notice is raised in this case, nor is this
behavior documented in the PHP manual. Instead of fixing it either
way, we lift the requirement to SQLite 3.5.0 (released on 2007-09-04)
instead of the former SQLite 3.3.9 (released on 2007-01-04).

Unbundle libsqlite3

Since there is no need to patch libsqlite3 for our purposes, and since
libsqlite3 ≥ 3.3.9 (which is our current requirement) is widely
available on distros, there is no reason anymore to bundle the library.

Besides removing the bundled libsqlite, and adapting the configuration
respectively, we also fix the use of the SQLITE_ENABLE_COLUMN_METADATA
compile time constant to detect whether sqlite3_column_table_name() is
available by a working feature detection (otherwise bug_42589.phpt
would fail). We also skip bug73068.phpt for libsqlite 3.11.0 to
3.14.1 which have a bug (<https://sqlite.org/src/info/ef360601>).

We also completely drop support for the obscure pdo_sqlite_external
extension (which could have been enabled on Windows only by passing
`--pdo-sqlite-external` to configure), since it is not needed anymore.

Furthermore, we remove references to the bundled libsqlite from
Makefile.gcov, CONTRIBUTING.md and README.REDIST.BINS.

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.
