"Export" relevant GD macros

For parity with non Windows systems, we should `AC_DEFINE` these macros
so that they are defined in config.w32.h instead of directly passed to
the compiler. This allows extensions which have ext/gd as dependency
to check for these macros. E.g. ext/ps does this[1], and fails to
build on Windows, because `HAVE_GD_BUNDLED` isn't defined.

Closes GH-7680.

Use the standard _WIN32 instead of the custom MSWIN32 in libgd

We're already checking `_WIN32` elsewhere in our bundled libgd, so it
makes no sense to also have a custom `MSWIN32`.

Export php_gd_libgdimageptr_from_zval_p()

Some extension may need to retrieve the `gdImagePtr` from an `GdImage`
object; thus, we export the respective function. To not being forced
to include gd.h in php_gd.h, we use the opaque `struct gdImageStruct *`
as return type.

We also rename php_gd2.dll to php_gd.dll, since there's not really much
point in giving the DLL a version number, since there is no php_gd.dll
for years (if there ever has been). Renaming, on the other hand,
matches the name on other systems (gd.so), and allows to actually use
`ADD_EXTENSION_DEP()`.

Add imagegetinterpolation()

While `imagesetinterpolation()` is available as of PHP 5.5.0,
there is no according getter function, so users would have to track the
current interpolation method manually.

To remedy this, we introduce `imagegetinterpolation()` as thin wrapper
for `gdImageGetInterpolationMethod()` (which has been introduced with
libgd 2.1.1), and use `im->interpolation_id` as fallback for older
libgd. Since our bundled libgd does not yet have this function, we add
it.

We also simplify the recently introduced bug79068.phpt, where it is
sufficient to check that the interpolation method has not been changed.

Support TGA reading

We add PHP bindings for libgd's features to read TGA files, which are
available as of libgd 2.1.0.

As PHP's bundled libgd doesn't yet include the respective features of the
external libgd, we add these.

Since TGA has no easily recognizable file signature, we don't add TGA
support for imagecreatefromstring() or getimagesize() and friends.

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.

Remove unused compilation unit

gd_arc_f_buggy.c has already been removed in GD 2.0.34RC, so we're also
getting rid of the file.

--enable-gd-native-ttf did set USE_GD_IMGSTRTTF, which is otherwise unused
as of commit 8a90aad3 (i.e. PHP 5.5.0), at least.

Replaced libvpx by libwebp (first draft; Windows only)

ext/gd/libgd/gd_webp.c has been taken from libgd[1]. Mainly, gd_error(X) has
been subsituted by zend_error(E_ERROR, X) and BGD_DECLARE(X) by X. Further
modifications are obvious from the diff.

All GD tests are passing, what raises hope, but we need more WebP tests,
anyway.
