intl: report more information about message pattern parse errors

The message patterns can be pretty complex, so reporting a generic
U_PARSE_ERROR without any additional information makes it needlessly
hard to fix erroneous patterns.

This commit makes use of the additional UParseError* parameter to
umsg_open to retrieve more details about the parse error to report that
to the user via intl_get_error_message()

Additional improve error reporting from the IntlMessage constructor.
Previously, all possible failures when calling IntlMessage::__construct()
would be masked away with a generic "Constructor failed" message.
This would include invalid patterns.

This commit makes sure that the underlying error that caused the
constructor failure is reported as part of the IntlException error
message.

Closes GH-6325.

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.

Always throw TypeException on throwing zpp failures

Introduces a ZEND_PARSE_PARAMS_THROW flag for zpp, which forces to
report FAILURE errors using a TypeException instead of a Warning,
like it would happen in strict mode.

Adds a zend_parse_parameters_throw() convenience function, which
invokes zpp with this flag.

Converts all cases I could identify, where we currently have
throwing zpp usage in constructors and replaces them with this API.
Error handling is still replaced to EH_THROW in some cases to handle
other, domain-specific errors in constructors.

Partial fix that allows internal constructors to set $this to null.
The address of $this passed to drectly called internal constructor in execute_data->return_value.
Internal constructors should use ZEND_CTOR_MAKE_NULL() macro (insted of previous ZEND_NULL(EG(This))) to do the work.

This patch doesn't fix the problem for indirectly called constructors. e.g. parant::__construct().
