Fixed bug #67169: []= after_array_splice incorrect

This fixes a regression I introduced in beta 1.

Reimplement strtr()

Fix strict array comparison

Fixes Symfony test failures

Combine HashTable.flags and HashTable.nApplyCount into single 32-bit word

Cleanup (1-st round)

Add only_integer_keys option to zend_hash_reindex

This allows to either do a full reindex, or only reindex the integer
keys.

Add zend_hash_splice

This implements the original functionality of php_splice, but
as an in-place operation, thus avoiding copying the HT.

Add zend_hash_splice

This implements the original functionality of php_splice, but
as an in-place operation, thus avoiding copying the HT.

This is much faster (~10x) if the splice removes a small portion
of the array and doesn't insert many elements.

array).

Refactored zend_hash_* iteration API zend_hash_fove_forward_ex(ht, pos) and family require second argument to be real pointer.
&(ht)->nInternalPointer should be passed instead of NULL.

Refactored zend_hash_* iteration API zend_hash_fove_forward_ex(ht, pos) and family require second argument to be real pointer.
&(ht)->nInternalPointer should be passed instead of NULL.
zend_hash_update_current_key() may work only with internal pointer.

Allocate HashTable->arData and HashTable->arHash at once

"incremental" hash bucket initialization

Refactored ZVAL flags usage to simplify various checks (e.g. Z_REFCOUNTED(), candidate for GC, etc)

Changed data layout to allow more efficient operations

Avoid useless memset()

Use STR_COPY() instead of STR_DUP() where possible

Refactored IS_INDIRECT usage for CV and object properties to support HashTable resizing

fix C89 compat

Revert "Add helper function for updating bucket contents"

Reverting this for now, because it would require further changes
thanks to the zend signals tsrms-but-only-sometimes awesomeness.

Rename+move zend_hash_apply_deleter and reuse it

The interruption handling was normalized to wrap the entire deletion
operation (instead of leaving out the destructor call and/or the
deallocation) per the recommendation of somebody (don't remember who)
familiar with zend signals.

There is an always-inlined variant of the function for use in
the main deletion function, to ensure there is no performance
impact.

Make zend_hash_apply_deleter() void, to allow reuse

Also remove lies in the comment above the function. apply_deleter
is not safe against modification, if the modification involves
removing the next bucket.

Also modified the implementation of zend_hash_graceful_destroy()
to be fully graceful (the reverse variant already was).

Add helper function for updating bucket contents

Remove unnecessary check

In case of an update the key already existed, so the next free
element can not change.

Fixed serialize/unserialize problems

Don't include trailing zero into hash caclculation

Fixed possible HashTable modification in its destructor
