Autoconf 2.59d (released in 2006) 1 started promoting several macros
as not relevant for newer systems anymore, including the AC_FUNC_VPRINTF.
This macro checks for presence of the vprint function otherwise checks
for presence of the _doprnt function. This check was relevant on very
old systems and today can be omitted since it should be well supported
by now. [2]
Also PHP doesn't use the HAVE_VPRINTF or HAVE_DOPRNT symbols.

Autoconf 2.59d (released in 2006) [1] started promoting several macros
as not relevant for newer systems anymore, including the `AC_STRUCT_TM`.
This macro checks if `struct tm` is defined in either `<sys/time.h>` or
`<time.h>` and defines the `TM_IN_SYS_TIME` symbol accordingly. This
check was relevant in times before the C89 for some embedded systems,
microcontrollers or very old systems. For newer systems it can be
avoided and the `<time.h>` should be included instead since current
systems should be well supported by now. [2]
Since PHP requires at least C89, this patch removes the obsolescent call
and time.h checks.

This patch makes several scripts and PHP development tools files
executable and adds more proper shebangs to the PHP scripts.
The `#!/usr/bin/env php` shebang provides running the script via
`./script.php` and uses env to find PHP script location on the system.
At the same time it still provides running the script with a user
defined PHP location using `php script.php`.
The AC_ARG_PROGRAM Autoconf macro provides program name transformations
when installing. This patch implements #64517 and prepares the
implementation for the request #60518.
In ./configure --help it additionally outputs --program-prefix=PREFIX,
--program-suffix=SUFFIX and the upcoming --program-transform-name=PROGRAM
option.
Macro AC_ARG_PROGRAM is available since Autoconf 2.0 and needs to be
called after the AC_CANONICAL_TARGET macro.

This change results in using the same buffer for multiple
stdio events which should fix inconsistencies of handling
messages that are not ended with a new line and possibly
very long messages that are split to multiple events.
