This is not actually related to SSL handshake but stream socket creation
which does not clean errors if the error handler is set. This fix
prevents emitting errors until the stream is freed.

RFC: https://wiki.php.net/rfc/dnf_types
This allows to combine union and intersection types together in the following form (A&B)|(X&Y)|T but not of the form (X|A)&(Y|B) or (X|A)&(Y|B)|T.
* Improve union type parsing

MAP_FIXED guarantees mmap will return that exact address or fail so the
address comparison is redundant.
The return value of this function is unused but I kept it because it
improves readability.
The new Linux 5.17 feature PR_SET_VMA_ANON_NAME can give names to
anonymous private memory, see:
https://lwn.net/Articles/867818/
It can be useful while debugging, to identify which portion of the
process's memory belongs to which subsystem.
This is how /proc/PID/maps can look like:
555ccd400000-555ccdc00000 r-xp 00000000 00:00 0 [anon:huge_code_pages]
7f6ec6600000-7f6ec6800000 rw-p 00000000 00:00 0 [anon:zend_alloc]
The first mapping is the PHP executable copied to anonymous memory by
option "opcache.huge_code_pages". The second one is a memory area for
the "zend_alloc.h" memory allocator library.
Unfortunately, it is not possible to give names to shared memory
(MAP_SHARED), because Linux MAP_SHARED really maps /dev/zero (see
shmem_zero_setup()), which makes madvise_vma_anon_name() believe this
is a file mapping, failing the prctl() with EBADF.
Also add a new ZEND_MM_NEED_EIGHT_BYTE_REALIGNMENT definition.
This fixes many [-Wsign-conversion] warnings.

* ext/oci8: use zend_string_equals()
Eliminate duplicate code.
* main/php_variables: use zend_string_equals_literal()
Eliminate duplicate code.
* Zend/zend_string: add zend_string_equals_cstr()
Allows eliminating duplicate code.
* Zend, ext/{opcache,standard}, main/output: use zend_string_equals_cstr()
Eliminate duplicate code.
* Zend/zend_string: add zend_string_starts_with()
* ext/{opcache,phar,spl,standard}: use zend_string_starts_with()
This adds missing length checks to several callers, e.g. in
cache_script_in_shared_memory(). This is important when the
zend_string is shorter than the string parameter, when memcmp()
happens to check backwards; this can result in an out-of-bounds memory
access.
* ext/opcache/ZendAccelerator: make check_persistent_script_access() static
* ext/opcache/ZendAccelerator: convert "int" to "bool"
* ext/opcache/zend_file_cache: convert "int" to "bool"
* ext/opcache: use true/false for zend_persistent_script.corrupted
* ext/opcache/ZendAccelerator: move duplicate code to zend_accel_discard_script()
* ext/opcache/ZendAccelerator: convert accel_deactivate_now() to function
Simplify the #iddef ZEND_WIN32.
* ext/opcache/zend_file_cache: simplify iovec initializer
* ext/opcache/zend_file_cache: add local zend_string* variables
Eliminates lots of redundant casts and avoids reloading the variable
from RAM into registers.
* ext/opcache/zend_file_cache: use ZSTR_VAL()
* ext/opcache/zend_file_cache: move code to zend_file_cache_script_write()
This eliminates duplicate error handling code.
- for packed arrays we store just an array of zvals without keys.
- the elements of packed array are accessible throuf as ht->arPacked[i]
instead of ht->arData[i]
- in addition to general ZEND_HASH_FOREACH_* macros, we introduced similar
familied for packed (ZEND_HASH_PACKED_FORECH_*) and real hashes
(ZEND_HASH_MAP_FOREACH_*)
- introduced an additional family of macros to access elements of array
(packed or real hashes) ZEND_ARRAY_ELEMET_SIZE, ZEND_ARRAY_ELEMET_EX,
ZEND_ARRAY_ELEMET, ZEND_ARRAY_NEXT_ELEMENT, ZEND_ARRAY_PREV_ELEMENT
- zend_hash_minmax() prototype was changed to compare only values
Because of smaller data set, this patch may show performance improvement
on some apps and benchmarks that use packed arrays. (~1% on PHP-Parser)
TODO:
- sapi/phpdbg needs special support for packed arrays (WATCH_ON_BUCKET).
- zend_hash_sort_ex() may require converting packed arrays to hash.
It's possible for delayed early binding opcodes to get optimized
away if they are "unreachable". However, we still need to attempt
early binding for them. (In some cases we also corrupt the early
binding list outright during optimization, which is how I got here.)
Fix this by storing information about delayed early binding
independently of DECLARE_CLASS_DELAYED opcodes, so early binding is
performed even after the opcode has been dropped.
Latest linux kernel use large number (12 bits for major device, 20
bits for minor device). Current code only supports previous standard
(5 chars), which means 8 bits for major and 8 bits for minor device.
It will fail if device number is out of that range. So this patch
increases device number read from /proc/self/maps file.
Closes GH-7512.
