build: Add sanitizer options
Build using Address Sanitizer (asan), Leak Sanitizer (lsan), or
Undefined Behavior Sanitizer (ubsan) by using one of these options for
the configure script:
--enable-asan
--enable-lsan
--enable-ubsan
For each of these to work, the compiler must support the requested
sanitizer and the requisite libraries must be installed (libasan,
liblsan, libubsan).
