trailing whitespace removal

Added new API function 'zend_string* zend_string_tolower(zend_string*)'.
It simplifies code and avoids unnecessary allocation and copying if string is already in lower case.

first shot remove TSRMLS_* things

secured unserialize

- update for BC-compatible unserialize
- add tests

Update get_class_name semantics

* get_class_name is now only used for displaying the class name
in debugging functions like var_dump, print_r, etc. It is no
longer used in get_class() etc.
* As it is no longer used in get_parent_class() the parent
argument is now gone. This also fixes incorrect parent classes
being reported in COM.
* get_class_name is now always required (previously some places
made it optional and some required it) and is also required
to return a non-NULL value.
* Remove zend_get_object_classname. This also fixes a number of
potential leaks due to incorrect usage of this function.

Remove zend_get_class_entry function

Remove support for classes without class entries

get_class_entry must be non-NULL and return non-NULL.

Fix counting of "R:" references in serialize()

Fix tests/serialize/bug64146.phpt

The var hash now retains a reference to its elements, to ensure
that addresses are not reused.

Furthermore the var hash now only stores objects

Fix tests/serialize/bug64146.phpt

The var hash now retains a reference to its elements, to ensure
that addresses are not reused.

Furthermore the var hash now only stores objects and references
and directly uses their pointer as key, thus making serialization
about two times faster.

Add smart_str_append for appending zend_strings

Also replaces usages in Zend/ and ext/standard

Move smart_str implementation into Zend/

So we can use it there as well...

For now I've retained the zend_smart_str_public.h header, though
it would probably be better to just m

Move smart_str implementation into Zend/

So we can use it there as well...

For now I've retained the zend_smart_str_public.h header, though
it would probably be better to just move that one struct into
zend_types.h.

Make number printing functions less generic

Now that zend_ulong is 64bit on 64bit platforms, it should be
sufficient to always use it, rather than supporting multiple
types.

Make number printing functions less generic

Now that zend_ulong is 64bit on 64bit platforms, it should be

API changes:
* _zend_print_unsigned_to_buf and _zend_print_signed_to_buf
no longer exist.
* smart_str(ing)_print_long and smart_str(ing)_print_unsigned
no longer exist.
* Instead of all these, zend_print_ulong_to_buf and
zend_print_long_to_buf should be used.
* smart_str_append_generic_ex no longer exists.
* smart_str(ing)_append_off_t(_ex) no longer exists, use
smart_str(ing)_append_long(_ex) instead.

Use append_unsigned instead of append_long where appropriate

Use inline functions for most of smart_str

smart_str_free_ex no longer exists, always use smart_str_free instead.

smart_str_alloc no longer requires a newlen variable to be in scope

Use inline functions for most of smart_str

smart_str_free_ex no longer exists, always use smart_str_free instead.

smart_str_alloc no longer requires a newlen variable to be in scope,
instead it returns the new length.
