We backport the slightly modified variant from master.
Duplicate metadata can only happen if someone tampers with the phar, so
we can and should treat that as error.
* PHP-7.3:
  Fix #79503: Memory leak on duplicate metadata
Partially reverts 846b647: instead of
throwing, this skips uninitialized typed properties when serializing objects.

This makes serialize with __sleep() behave the same as serialize()
without __sleep().

As in the non-__sleep() case, unserialize(serialize($x)) identity
may not be preserved due to replacement of uninitialized/unset
properties with default values. Fixing this will require changes to
the serialization format.

Closes phpGH-5396.
(cherry picked from commit a1a044d
on author's explicit request)
* PHP-7.3:
  Add additional preg_match test case
We have to destroy (un-opened) ZEND_HANDLE_FILENAMEs.
We add support for Activision HSM (`IO_REPARSE_TAG_ACTIVISION_HSM`) and
VFS for Git (`IO_REPARSE_TAG_PROJFS`).  The latter fixes bug #78784.
* PHP-7.3:
  Fix #79470: PHP incompatible with 3rd party file system on demand
We add a `get_properties` handler which complements the already
existing `has_property` and `read_property`handlers.
* PHP-7.3:
  Bump version
This reverts commit 6bc8f7e.

This causes an assertion failure in PHPUnit.
The timeout is only real-time based on Windows. Make this use
a busy wait loop instead. If hard_timeout is broken, this will
fail with a run-tests enforced timeout instead.
We have to actually determine the proper `SIZEOF_OFF_T`.
Interestingly, it is `4` on Windows x64.

We also have to prevent the redefinition in pg_config.h.  The clean
solution would likely be to not include pg_config.h at all, but that's
out of scope for BC reasons for now.
* 'PHP-7.4' of git.php.net:/php-src:
  Fix #79532: sizeof off_t can be wrong
  Make 045.phpt busy wait
  Revert "Fix #79065: DOM classes do not expose properties to Reflection"
  Bump version
  Fix #79065: DOM classes do not expose properties to Reflection
  Fix #79470: PHP incompatible with 3rd party file system on demand
On Windows, reusing/sharing of OPcache instances with different
configuration is not necessarily supported, so we have to make that it
does not happen for the clean scripts, by using `$orig_ini_settings`
instead of `$clean_params`.
Let's go from 32 to 16 parallel jobs. We can reduce this further
if necessary.

Closes phpGH-5426.
Revert "Fix #61597: SXE properties may lack attributes and content"

This reverts commit 7c081db.
* PHP-7.3:
  Fix #79528: Different object of the same xml between 7.4.5 and 7.4.4
This function is lacking any tests so far.
* PHP-7.3:
  Add basic sapi_windows_cp_conv() test
Disabling postgresql entirely for now, because I can't figure out
how to fix it. Something broke big time with i386 packages on
Azure pipelines.
We did not allocate a cache slot for FETCH_CLASS. This is already
fixed on newer PHP versions.
* PHP-7.3:
  Fixed bug #79535
nikic and others added 26 commits July 9, 2020 11:54
Some of the code paths leading to this do not fetch op data.
Hopefully this fixes the release build failure.
Both tests used the same folder, which could clash in case the tests
are run simultaneously.
* PHP-7.3:
  Fix some memory bugs in ldap.c
We mark symlink_link_linkinfo_is_link_error2.phpt as XFAIL on Windows
ZTS.  Several Windows API file system functions ignore trailing spaces
in absolute filenames after the final directory separator, which causes
`link(' ', $link)` to actually call `CreateHardLink()` which then
fails, because linking folders is not supported.  However, with NTS
builds (as well as on other systems), the $target is found to not
exist, so the function fails without actually attempting to create the
link.  This needs further investigation.
These tests fail on Windows for different reasons, but not because
symlinks, links, or lstat() would not be supported on Windows
generally.
Use *_IND macros in a few places in string.c.
* PHP-7.3:
  Fixed bug #79817
HashTable was reallocated (zend_hash_packed_grow) during php_var_dump, so we should call GC_ADDREF to make SEPARATE_ARRAY work.

Closes phpGH-5837.
* PHP-7.3:
  Fixed bug #79821
This also fixes memory error in debug_zval_dump and var_export.
* PHP-7.3:
  Fixed bug #79830 introduced by fixing bug #79821
It introduced by fixing bug #79830
* PHP-7.3:
  Fixed BC break of php_debug_zval_dump
`st_dev` deliberately overflows on such systems, cf.
<http://svn.php.net/viewvc?view=revision&revision=350100>.
* PHP-7.3:
  Fixed bug #79849
* upstream/PHP-7.4:
  Fix test for x86 Windows
Similar to what is done for ReflectionType itself, copy the
type name stored inside ReflectionProperty. Also make sure the
type field is always initialized for dynamic properties.

This is a non-issue in PHP 8, because we store a pointer to the
property_info there, rather than a copy.
While the comparison result changes, the equality comparison is not
going to care about it in the end.

even without sanitizers, it is reproducible but with the following

```
<?php
$g = gmp_init(256);
var_dump(gmp_pow($g, PHP_INT_MAX));

we get this
