  About ASan: AddressSanitizer a.k.a. ASan is a widely-used debugging tool to detect memory access
errors. It helps to detect issues like use-after-free, various kinds of buffer overruns in C/C++
programs, and other similar errors, as well as printing out detailed debug information whenever
an error is detected. ASan is integrated with gcc and clang and can be enabled via a meson option:
-Db_sanitize=address, See the documentation for details (especially regarding clang).

About ASan test: DTS adds one parameter named asan to control ASan test, It contains three steps:
 - Append ASan build parameters to meson build options. this may open the function of ASan detect
   memory access errors. if occuring memory access errors, the stack info will recorded in DTS log

 - After all cases tested finish, analyze DTS log and redefine case test result according to whether
   case log contain memory access error info. modify the result to failed if contain otherwise inherit
   the original result.

 - Generate ASan report to distinguish it from the original report.
