Fix #77594: ob_tidyhandler is never reset

We reset to original INI value on request shutdown.

Closes GH-6425.

Don't crash on uninitialized tidy object

"Uninitialized" here means that the object was created ordinarily
-- no constructor skipping involved. Most tidy methods seem to
handle this fine, but these three need to be guarded.

Fix #77040: tidyNode::isHtml() is completely broken

The documentation of `tidyNode::isHtml()` states that this method
"checks if a node is part of a HTML document". That is, of course,
nonsense, since a tidyNode is "an HTML node in an HTML file, as
detected by tidy."

What this method is actually supposed to do is to check whether a node
is an element (unless it is the root element). This has been broken by
commit d8eeb8e[1], which assumed that `enum TidyNodeType` would
represent flags of a bitmask, what it does not.

Closes GH-6290.

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.

Add zend_object_alloc() API

Using ecalloc() to create objects is expensive, because the
dynamic-size memset() is unreasonably slow. Make sure we only
zero the main object structure with known size, as the properties
are intialized separately anyway.

Technically we do not need to zero the embedded zend_object
structure either, but as long as the memset argument is constant,
a couple more bytes don't really matter.
