Bug #9954 mysql-4.1.11/cmd-line-utils/libedit/makelist.sh is not portable

  - Changed makelist.sh
  - Bump up required version of autoconf
  - Use new style to init mutex in my_thr_init


cmd-line-utils/libedit/makelist.sh:
  Changed file so it works also on windows cr/lf files.
configure.in:
  Bump up required AC version number so that correct version of aclocal and autoconf is selected.
include/my_pthread.h:
  Use PTHREAD_MUTEX_ADAPTIVE_NP to see if "fast" mutexes are available
  Remove "errorcheck" mutexes, since they are never used.
mysys/my_thr_init.c:
  Use new style functions to init mutex if PTHREAD_ADAPTIVE_MUTEX_INITIALIZER_NP is defined
  Add comment what mutex "kind" means

Note that the following statement may give a compiler warning under
some configurations, but there isn't anything we can do about this as
this is a bug in the header files for the thread implementation
Set mutex type to "fast" a.k.a "adaptive"
The mutex kind determines what happens if a thread attempts to lock
a mutex it already owns with pthread_mutex_lock(3). If the mutex
is of the ``fast'' kind, pthread_mutex_lock(3) simply suspends
the calling thread forever. If the mutex is of the ``error checking''
kind, pthread_mutex_lock(3) returns immediately with the error
code EDEADLK.
