FAQ/configure: update with recent autoconf
capiinfo/configure.ac: updated from configure.in

* rename configure.in to configure.ac for recent autotools
* require autoconf 2.68
* update obsolete macros
* quote arguments to AC_../AM_.. macros
* remove unneeded options --with-sbin / --with-man:
  --sbindir / --mandir serve exactly the same purpose
capiinfo: autoreconf

Update all files generated by autotools via a call to 'autoreconf -if'.
capiinfo/capiinfo.c: silence a compiler warning
isdnctrl/configure.ac: updated from configure.in

* rename configure.in to configure.ac for recent autotools
* require autoconf 2.68
* update obsolete macros
* quote arguments to AC_../AM_.. macros
* remove unneeded options --with-sbin / --with-man:
  --sbindir / --mandir serve exactly the same purpose
isdnctrl: autoreconf

Update all files generated by autotools via a call to 'autoreconf -if'
and remove unnecessary file acconfig.h.
rcapid/configure.ac: updated from configure.in

* rename configure.in to configure.ac for recent autotools
* require autoconf 2.68
* update/remove obsolete macros
* quote arguments to AC_../AM_.. macros
* remove unneeded options --with-sbin / --with-man:
  --sbindir / --mandir serve exactly the same purpose
rcapid: autoreconf

Update all files generated by autotools via a call to 'autoreconf -if'.
capi20/configure.ac: updated

* require autoconf 2.68
* update obsolete macros
* generate header file config.h
* quote arguments to AC_../AM_.. macros
capi20: autoreconf

Update all files generated by autotools via a call to 'autoreconf -if'
and add generated template config.h.in.

Note: the file config.h genereted from config.h.in by 'configure'
is not used (i.e. #include'd) yet in those source files that use
the preprocessor directive CAPI_LIBRARY_V2, namely capifunc.c,
capiutils.h, convert.c.
The problematic file is capiutils.h, as it is a public header file
for libcapi20, thatshould not pretend to offer two interfaces
based on a preprocessor directive.
Maybe we need to generate if from capiutils.h.in ;-)
