build: Add sanitizer options

Browse Source 
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).
