- Use tabs instead of spaces for indentation

- Proper m4 quoting of parameters

- Fix broken AC_ARG_* handling:
  --without-foo/--disable-foo set withval="no"/enableval="no"
  and the third parameter of the AC_ARG_* macros is always
  "user provided an --with*-foo/--*able-foo option" _NOT_ "yes",
  while the fourth parameter is "user didn't provide this option"
  (= the default if neither --with-foo/--enable-foo nor --without-foo/--disable-foo
     has been set)

- Drop FTDM_CFLAGS in MY_CFLAGS (what was that used for anyway?)

- Drop MYLIB

- Drop SOLINK (unused)

- Rename MY_CFLAGS to FTDM_CFLAGS

- Rename all AM_CONDITION variables to HAVE_* for (optional) dependencies
  and WANT_* for features

- Reorder mod_LTLIBRARIES lines

- Move some things in configure.ac around to group them

- Add -shared to modules LDFLAGS (we don't need "ftmod_foo.a" static modules, do we?)

- Import ax_compiler_vendor.m4, drop the macro definition from configure.ac

- Add AUTOMAKE_OPTS to Makefile.am and define FreeTDM as a foreign (= non-GNU) project

- Add ACLOCAL_FLAGS to Makefile.am and set AC_CONFIG_MACRO_DIR in configure.ac
  custom m4 macros are kept in the build subdirectory

- Enable silent rules for automake-1.11 and newer (use make V=1 to get verbose output)

- configure option --with-modinstdir requires a value now and quits with an error message
  if called without one (e.g. "./configure --without-modinstdir" or "./configure --with-modinstdir")

- Add configuration summary screen and category headers for modules in configure output

- Requires non-public development version of libisdn(!)
- Based on older patches from http://oss.axsentis.de/gitweb/?p=ftmod_isdn.git;a=summary
- Rework of ftmod_isdn related buildsystem parts (Makefile.am, configure.in and libpcap.m4)

mod_callcenter: Make callcenter_config agent get return the value of the item requested.  Also added queue param max-wait-time-with-no-agent-time-reached: If the max-wai-time-with-no-agent is already reached for the queue, then new caller can wait for x ammount of second before it kicked out of the queue rather than get rejected automaticly.

add -ncwait for Unix based implememtations to make the backgrounder wait to make sure the process starts before detaching

fix race in codec failure condition, then fix bug in sdp parsing (likely a regression from recent codec changes) to never have the problem in the first place so you are double-protected
