Formerly, this had to be enabled by passing the configuration flag
`--enable-crt-debug`; now it can be enabled by setting the environment
variable `PHP_WIN32_DEBUG_HEAP`. The advantage is that it is no longer
necessary to do separate builds, at the cost of a very minor
performance penalty during process startup.

Building with `/W3` shows an awful lot of warnings on Windows, so it's
really hard to spot the more important ones. Since it is not possible
to override the hard-coded `/W3`, we drop it altogether, so MSVC uses
the default `/W1`. Users are encouraged to increase the warning level
via the environment variable `CFLAGS` before doing configure.
We also enable `/WX` (treat warnings as errors) for AppVeyor CI, using
`/W1` for now, since otherwise the build would fail.

`zend_llist_add_element()` and `zend_llist_prepend_element()` now
explicitly expect a *const* pointer.
We use the macro `ZEND_VOIDP()` instead of a `(void*)` cast to suppress
C4090; this should prevent accidential removal of the cast by
clarifying the intention, and makes it easier to remove the casts if
the issue[1] will be resolved sometime.

This is basically the same as commit 3427545[1], but for Windows.

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.

Since DIR_W32.offset is declared as `uint16_t`, we have an overflow for
directories with many entries. This patch changes the field to
`uint32_t`.

Prefer '%define api.value.type' to '#define YYSTYPE', so that Bison
know the type.
Use '%code requires' to declare what is needed to define the api.value.type
(that code is output in the generated header before the generated
definition of YYSTYPE).
Prefer '%define api.prefix' inside the grammar file to '-p' outside,
as anyway the functions defined in the file actually use this prefix.
Prefer `%param` to both `%parse-param` and `%lex-param`.

In the buildconf and configure batch files, Windows' cscript utility was being
run without the /e:jscript flag. This works on systems that have not had the
default .js file association changed, but if .js has been re-associated to
(say) an IDE, the batch files fail with the error message:
Input Error: There is no script engine for file extension ".js".

Disable optimizations for ASan instrumented builds

ASan instrumentation does not support the MSVC debug runtime, but still
it does not make sense to enable optimizations for such builds, since
they are not meant for production usage anyway, and although memory
corruption issues are still found in optimized builds, the generated
diagnostics are close to being useless, and apparently sometimes even
outright wrong. Therefore, we disable all optimizations for ASan
instrumented builds.
We also introduce and use `ZEND_WIN32_NEVER_INLINE` for ASan enabled
builds to avoid inlining of functions, so we get even better
diagnostics.

In the php-src repository, the test runner is named run-tests.php, but
when it is copied to the tests packs, it is renamed to run-test.php.
This renaming does not make sense, and is actually somewhat confusing.
Although changing the name back to run-tests.php constitutes a BC
break, we think the benefit of having a single name outweights the
disadvantages in the long run.

Currently mail related tests are split for *nix and Windows (if there
are even Windows versions). The basic difference is that the *nix
variants set the INI directive sendmail_path to just write the email to
disk, while the Windows tests use ext/imap. The latter tests are way
more verbose, and such duplicated tests are generally a pain point.
Furthermore, the Windows tests are much slower, and could not be run
without ext/imap being available.
We therefore introduce a small fakemail application, which basically
works like `tee <path> >/dev/null`, and which will be shipped with the
Windows tests packs. fakemail.exe would also need to be added to the
PHP binary SDK, so these tests could be run during developments.
To cater to the remaining differences, we also introduce support for
`{MAIL:<path>}` placeholders in the INI sections to run-tests.php. How
to use this can be seen in mail_basic.phpt, which is currently the only
modified test case, because these tests are yet supposed to fail on
Windows, due to the missing fakemail.exe in the PHP SDK.

Snapshot builds are release builds, and therefore enabling sanitizers
is undesireable.

We no longer try to retrieve the filename of a given stream when

in PHP 7.3 and earlier, we regard this as sensible trade-off.

Since we need `headers_lc` as well as `headers_trim` in the following,
we do not release the former even if they are the same string, to avoid
complicating the release logic even more.
A new test case is not necessary, since we already have
mail_basic_alt2-win32.phpt and others.
