Subject: [PATCH 14/21] upatch-build: fix 'file detection cause build failure'
issue
File relation detection does not work as we expected sometimes.
We changed the way to parse file relations from parsing dwarf info
to reading symlink, which is generated by hijacker.
This method would list all generated symlinks after each build,
finding the file it points to and create a file map. Because of build results
are same, we can use the symlink path as a KEY to find the relationship
between patched objects and original objects, which is the previous step for
comparing difference of each build.
Sometimes, the directory of generated objects may be different than source
directory. Thus, we provide a new argument '--object-dir', which would be
same as '--source-dir' by default.

Subject: [PATCH 20/21] upatch-diff: only check changed file symbols
1. sync compare results (SAME/NEW/CHANGED) to correlated objects
2. mark file changes by looking up symbol changes
3. check orignal object & debuginfo when file changes were detected
4. defer symbol check until after calculation changes
