common: 2 new debug logging levels for low system memory and package info

DAPL_DBG_TYPE_SYS_WARN = 0x800000
DAPL_DBG_TYPE_VER = 0x1000000

export DAPL_DBG_SYS_MEM = 5 will set the checking for memory less than 5%
when DAPL_DBG_TYPE is set with bit DAPL_DBG_TYPE_SYS_WARN.

The package must be built with --enable-counters for memory checking to
be enabled.

In addition, if DAPL_DBG_TYPE -s set with bit DAPL_DBG_TYPE_VER than
the package rev and build date will be sent to stdout during library
init.
