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.

Fixed wrong zval_dtor() usage

Use zval_ptr_dtor() instead of zval_dtor() in internal functions that destroy new created object (This is safer and produces less code)

Replace legacy zval_dtor() by zval_ptr_dtor_nogc() or even more specialized destructors.
zval_dtor() doesn't make a lot of sense in PHP-7.* and it's used incorrectly in some places.

Add _IS_NUMBER as cast_object() target type

convert_scalar_to_number() will now call cast_object() with an
_IS_NUMBER argument, in which case the cast handler should return
either an integer or floating point number, whichever is more
appropriate.

Previously convert_scalar_to_number() unconditionally converted
objects to integers instead.

Move constants into read-only data segment

Add gmp_kronecker()

Exposes the mpz_kronecker(), mpz_si_kronecker() and
mpz_kronecher_si() for computing the Kronecker symbol.

Add gmp_perfect_power()

Exposes the mpz_perfect_power_p() function.

We already had the more specific gmp_perfect_square() function.

Add gmp_lcm()

Exposes mpz_lcm() and mpz_lcm_ui() for calculating the least
common multiple.

We already expose the somewhat complementary gmp_gcd() function.

Add gmp_binomial()

Adds PHP bindings for mpz_bin_ui and mpz_bin_uiui, for calculating
binomial coefficients.
