RC manipulation cleanup

Remove some unnecessary duplications

Prevent reference-counting on persistent zvals (internal constants, default properties and constants of internal classes).
New macro ZVAL_COPY_OR_DUP() is used perform duplication, if necessary.

Prevent reference-counting on persistent zvals (internal constants, default properties and constants of internal classes).
New macro ZVAL_COPY_OR_DUP() is used perform duplication, if necessary.
This should eliminate related race-coditions in ZTS build and prevent reference-counting bugs after unclean shutdown.

Mostly the callback name is only used to report an error. Try to
avoid calculating it if no error occurred.

Don't leave holes in func_get_args() and backtraces

Argument lists should always be continuous and hole-free, even if
local variables are unset. Replace UNDEF values with NULLs.

Updated some str functions to new parameter API

Interned strings unification for TS/NTS

Hereby, interned strings are supported in thread safe PHP. The patch
implements two types of interned strings

- interning per process, strings are not freed till process end
- interning per request, strings are freed at request end

There is no runtime interning.

With Opcache, all the permanent iterned strings are copied into SHM on
startup, additional copying into SHM might happen on demand.
