Add new option '--asan' for configuration to support dynamic
Address-Sanitizier debugging, which could detect kinds of invalid
memory accessing problems(eg. UAF, r/w OOB, etc.). Currently, only
ubifs-utils(mkfs.ubifs/fsck.ubifs) is supported.
Enable Address-Sanitizier debugging with configuration:
./configure --enable-asan
Notice: The Address-Sanitizier will stop the program and print
problems if memory problems are detected. Sometimes the memory
problems come from third libs(not mtd-utils), which could stuck
the testcases.
