When configure detects some NO_XXX or NEEDS_XXX is unneeded, unset
this variable (actually set it to empty string).  This allow
autodetection to override the default set in Makefile.

The cmd_usage() routine was causing warning messages due to a NULL
format parameter being passed in three out of four calls. This is a
problem if you want to compile with -Werror. A simple solution is to
simply remove the GNU __attribute__ format pragma from the cmd_usage()
declaration in the header file. The function interface was somewhat
muddled anyway, so re-write the code to finesse the problem.

[jc: this incidentally revealed that t9100 test assumed that the output
 from "git help" to be fixed in stone, but this patch lower-cases
 "Usage" to "usage".  Update the test not to rely on "git help" output.]

These changes were originally part of the next patch, but have been
split out since they were peripheral to the main purpose of that patch.

  - update comment describing the signature format to reflect
    the current code.
  - remove trailing \n in calls to error(), since a \n is already
    provided by error().
  - remove redundant call to get_sha1_hex().
  - call sha1_to_hex(sha1) to convert to ascii, rather than attempting
    to print the raw sha1.

The new tests provide a regression suite to support the modifications
to git-mktag in this and the next patch.

This moves the built-in "always-use-pager" logic for log family
to the command dispatch table of git wrapper.  This makes it
easier to change the default use of pager, and has an added
benefit that we fork and exec the pager early before packs are
mmapped.

git-ls-files was broken by the setup_git_directory() calling changes,
because I had missed the fact that the "prefix" variable in that file was
static to the whole file, and unlike git-ls-tree (where I had fixed it
up), it ended up using two different variables with the same name
depending on what the scoping happened to be.

This fixes it up properly (by just removing the static variable, and
passing the automatic one around properly), and git-ls-files should work
again.

Doing an "strace" on "git diff" shows that we close() a file descriptor
twice (getting EBADFD on the second one) when we end up in ce_compare_data
if the index does not match the checked-out stat information.

The "index_fd()" function will already have closed the fd for us, so we
should not close it again.
