Add zend_string_init_fast() as a helper for the empty string /
one char interned string / zend_string_init() pattern.

Also add corresponding ZVAL_STRINGL_FAST etc macros.

Ensure ctype_string is NULL for C locale

We already document that this is the case, but currently it's only
true if setlocale() has not been called. Make sure ctype_string is
always NULL, even with an explicit "C" locale call, so we can
more efficiently check whether we are in the "C" locale.

(minus maximum look-behind, but let's ignore that), so we can

Fix php_pcre_mutex_free()

We should only set the mutex to NULL if we actually freed it.
Due to missing braces non-main threads may currently set it to
NULL first.

Add pcre_get_compiled_regex_cache_ex() with local_aware flag

A new function `pcre_get_compiled_regex_cache_ex()` is introduced,
which allows to compile regexp pattern using the "C" locale instead
of a current locale.

This will be needed to replace setlocale() usage in fileinfo,
which is not thread-safe.
