Remove AC_FUNC_UTIME_NULL

Autoconf 2.59d (released in 2006) [1] started promoting several macros
as not relevant for newer systems, including the AC_FUNC_UTIME_NULL.

This macro checks if `utime(file, NULL)` sets file's timestamp to the
current time and defines the `HAVE_UTIME_NULL` symbol. This check was
relevant on very old systems (for example, 4.3BSD released in 1986) and
today can be omitted for systems with utime since it should be well
supported by now. [2]

Remove AC_FUNC_VPRINTF

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.

Implement #64517: Add AC_ARG_PROGRAM macro

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.
