Catch potential exceptions during to string conversion

As of PHP 7.4.0, exceptions are allowed to be thrown from inside

exceptions early.

Fix #64130: COM obj parameters passed by reference are not updated

`ITypeInfo_GetIDsOfNames()` is supposed to fail with `E_NOTIMPL` for
out-of-process servers, thus we should not remove the already available
typeinfo of the object in this case.

We also properly free the `byref_vals`.

Avoid double-free

As of commit b2e3fd1[1] the `authid.User` is no longer newly allocated,

Fix #48585: com_load_typelib holds reference, fails on second call

Whether the type library is cached is actually irrelevant here; what
matters is that the symbols are imported, and since these are not
cached, we have to import them for every request. And we cannot cache
the symbols, because the import depends on the current codepage, but
the codepage is a `PHP_INI_ALL` setting.

Fix #63527: DCOM does not work with Username, Password parameter

We must not mix multibyte and wide character strings in the
`COAUTHIDENTITY` structure. Using wide character strings throughout
would have the advantage that the remote connection can be established
regardless of the code page of the server, but that would more likely
break BC, so we just drop the wide character string conversion of the
username.

Fix TsHashTable related race conditions

Although TsHashTable and the according API are supposed to easily make
a HashTable thread-safe, they do not; for instance, there can be race
conditions between finding and updating entries. We therefore avoid
the usage of TsHashTable in favor of a HashTable with our own mutex
management.

The patch has been provided by krakjoe@php.net; I only did some minor
fixes and tweaks.

Deprecate case-insensitive constants via typelib import

As of PHP 7.3.0, case-insensitive constants are deprecated. We catch
up on this with regard to ext/com_dotnet, which allows to import
constants from typelibs, by triggering a deprecation notice whenever
`com_load_typelib()` is called with `$case_sensitive` being `false`,
and whenever `com.autoregister_casesensitive` is set to `false`,
regardless of whether there are actually constants in the typelib which
would be imported.

Remove local variables

This patch removes the so called local variables defined per
file basis for certain editors to properly show tab width, and
similar settings. These are mainly used by Vim and Emacs editors
yet with recent changes the once working definitions don't work
anymore in Vim without custom plugins or additional configuration.
Neither are these settings synced across the PHP code base.

A simpler and better approach is EditorConfig and fixing code
using some code style fixing tools in the future instead.

This patch also removes the so called modelines for Vim. Modelines
allow Vim editor specifically to set some editor configuration such as
syntax highlighting, indentation style and tab width to be set in the
first line or the last 5 lines per file basis. Since the php test
files have syntax highlighting already set in most editors properly and
EditorConfig takes care of the indentation settings, this patch removes
these as well for the Vim 6.0 and newer versions.

With the removal of local variables for certain editors such as
Emacs and Vim, the footer is also probably not needed anymore when
creating extensions using ext_skel.php script.

Additionally, Vim modelines for setting php syntax and some editor
settings has been removed from some *.phpt files. All these are
mostly not relevant for phpt files neither work properly in the
middle of the file.

Fix localized error messages and memory leaks

The FormatMessage API needs to LocalFree the delivered error messages.
In cases where messages are delivered in non ASCII compatible encoding,
the messages might be unreadable. This aligns the error message encoding
with the encoding settings in PHP, the focus is UTF-8 as default.

Remove unused Git attributes ident

The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.

In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.

This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
