Fix stubs for bzerr* functions

These can return false if the stream is not a bz2 stream. Also
emit a warning in this case, this should not be failing silently.

Make $use_less_memory a boolean parameter

Change leftover RETURN_FALSE to RETURN_THROWS() from 4095c0a

Promote empty filename to ValueError in BZ2 extension

Review the usage of apostrophes in error messages

Closes GH-5590

Remove proto comments from C files

Closes GH-5758

Fix [-Wundef] warning in BZip2 extension

Improve some TypeError and ValueError messages

Closes GH-5377

Improve some ValueError messages

Closes GH-5340

Improve gen_stub.php

Closes GH-5350
Add support for generating deprecated function entries, as well as forward declaration
of function aliases.

Improve error messages of various extensions

Closes GH-5278

Make error messages more consistent by fixing capitalization

Closes GH-5066 As a first step, let's capitalize their initial letter when it is applicable.

Convert some warnings to Errors in BZip2

Closes GH-4984

Use RETURN_THROWS() after zend_type_error()

Use RETURN_THROWS() during ZPP in bz2, calendar, com_dotnet extensions

Add type error on filename which contain null bytes in bzopen

Remove mention of PHP major version in Copyright headers

Closes GH-4732.

Don't explicitly set return value on ZPP failure

Failing ZPP throws as of PHP 8.0.0, so explicitly setting a return
value is useless, and also slightly confusing.

Creating stub for ext bz2

Report errors from stream read and write operations

The php_stream_read() and php_stream_write() functions now return
an ssize_t value, with negative results indicating failure. Functions
like fread() and fwrite() will return false in that case.

As a special case, EWOULDBLOCK and EAGAIN on non-blocking streams
should not be regarded as error conditions, and be reported as
successful zero-length reads/writes instead. The handling of EINTR
remains unclear and is internally inconsistent (e.g. some code-paths
will automatically retry on EINTR, while some won't).

I'm landing this now to make sure the stream wrapper ops API changes
make it into 7.4 -- however, if the user-facing changes turn out to
be problematic we have the option of clamping negative returns to
zero in php_stream_read() and php_stream_write() to restore the
old behavior in a relatively non-intrusive manner.

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 arginfo for bzcompress

bzcompress() has 1 required parameter, not 2.

See http://php.net/manual/en/function.bzcompress.php or invoke

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.
