configure: Remove AC_HEADER_STDBOOL, AC_C_ and AC_TYPE_ macros

The following macros check if particular C types in specific header file
exists, these header files defines them and are already included in the
source code. So, remove them.

AC_HEADER_STDBOOL - stdbool.h
AC_TYPE_INT and AC_TYPE_UINT - stdint.h or inttypes.h
AC_TYPE_OFF_T and AC_TYPE_UID_T - sys/types.h
AC_TYPE_SIZE_T - stddef.h, string.h, stdlib.h or stdio.h

Remove AC_C_CONST and AC_C_INLINE as gcc supports inline and const
keywords.
