clang-analyzer: adding clang static analysis support
clang static analyzer is a source code analysis tool that
finds bugs in C, C++.
This patch automates clang analyzes part by integrating
it with 'make clang-check'
clang-checker.sh: runs clang analyzer with and without the
HEAD commit, and shows the bugs introduced by HEAD commit (if any)
sample report:
$[ glusterfs ]: make clang-check
================ Clang analyzer in progress ================
