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 unused variable warning in curl

Fix 77264: curl_getinfo returning microseconds, not seconds

Since curl 7.55.0, libcurl introduced new constants to return
more sensible variable types with curl_getinfo.

When curl_getinfo with no option was called, and curl >= 7.55.0, some
of the result were returned as int when they where returned as float
in previous versions. This commit remove this BC Break.

If someone still want to use more sensible variable types, it's always
possible to call curl_getinfo with newer constants.

CURLINFO_CONTENT_LENGTH_DOWNLOAD => CURLINFO_CONTENT_LENGTH_DOWNLOAD_T
CURLINFO_CONTENT_LENGTH_UPLOAD => CURLINFO_CONTENT_LENGTH_UPLOAD_T
CURLINFO_SIZE_DOWNLOAD => CURLINFO_SIZE_DOWNLOAD_T

CURLINFO_SPEED_DOWNLOAD => CURLINFO_SPEED_DOWNLOAD_T
CURLINFO_SPEED_UPLOAD => CURLINFO_SPEED_UPLOAD_T
CURLINFO_APPCONNECT_TIME => CURLINFO_APPCONNECT_TIME_T
CURLINFO_CONNECT_TIME => CURLINFO_CONNECT_TIME_T
CURLINFO_NAMELOOKUP_TIME => CURLINFO_NAMELOOKUP_TIME_T
CURLINFO_PRETRANSFER_TIME => CURLINFO_PRETRANSFER_TIME_T

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.

Since 7.52.x libcurl file:// scheme was implemented in a way described
in https://tools.ietf.org/html/draft-ietf-appsawg-file-scheme-16 . The
draft is still not accepted and the change contained a BC breach with
win32 path handling. It was reported upstream and 7.52.x fixed it, but
the BC breaching behavior was reintroduced in 7.56.1. Thus, it is better
to handle this on the PHP side.
