Feature: add git repo reference to mdsdcl

git commands has been added to obtain the RELEASE_TAG from git if the code has been
installed from sources. All added information are written to mdsdcl structure that
can be accessed through "mdsdcl show git", with some further optional qualifiers:
TAG, BRANCH, COMMIT, REMOTE, REMOTE_URL

the GIT_TAG is formatted as follow:
 [closest_release_tag]-[number_of_commit_ahead]-g[short_commit_hash]<"M" if code has uncommitted changes>

Some additional improvement have been also added within the same commit:
1) a help-more command that writes the commented targets tagged with ##@@argument
2) the autmatic reconfigure upon changes in any Makfile.in
3) a new configure parameter --disable-uncommitted-install prevent install
   action if there are uncommitted changes
