Remove the "say" function, with various rewrites of the remaining
git-*.sh code to C and the preceding change to have git-submodule.sh
stop using the GIT_QUIET variable there were only four uses in
git-subtree.sh. Let's have it use an "arg_quiet" variable instead, and
move the "say" function over to it.

The only other use was a trivial message in git-instaweb.sh, since it
has never supported the --quiet option (or similar) that code added in
0b624b4c

 (instaweb: restart server if already running, 2009-11-22)
can simply use "echo" instead.

The remaining in-tree hits from "say" are all for the sibling function
defined in t/test-lib.sh. It's safe to remove this function since it
has never been documented in Documentation/git-sh-setup.txt.
