If the source repository was packed, and git-local-fetch needed to
fetch a pack file, it spewed a misleading error message about not
being able to find the unpacked object.  Fixed by adding the

of error messages in case the source file does not exist.

"git-local-fetch -s" did not work with a packed repository, because
symlink() happily created a link to a non-existing object file,
therefore fetch_file() always returned success, and fetch_pack() was
not called.  Fixed by calling stat() before symlink() to ensure the
file really exists.

When making changes to different files (i.e. dirty working tree) and
committing logically separate changes in groups, often it is necessary
to run 'git diff --cached HEAD' to make sure that the changes being
committed makes sense.  Saying 'git diff --cached' by mistake gives
rather uninformative error message from git-diff-files complaining it
does not understand --cached flag.

The call to parse_object() in process() is not actually needed - if
the object type is unknown, parse_object() will be called by loop();
if the type is known, the object will be parsed by the appropriate
process_*() function.

After this change blobs which exist locally are no longer parsed,
which gives about 2x CPU usage improvement; the downside is that there
will be no warnings for existing corrupted blobs, but detecting such
corruption is the job of git-fsck-objects, not the fetch programs.
Newly fetched objects are still checked for corruption in http-fetch.c
and ssh-fetch.c (local-fetch.c does not seem to do it, but the removed
parse_object() call would not be reached for new objects anyway).

After adding the SEEN flag, the SCANNED flag became obviously
redundant - each object can get into process_queue through process()
only once, and therefore multiple calls to process_object() for the
same object are not possible.

The process() function is very often called multiple times for the
same object (because lots of trees refer to the same blobs), but did
not have a fast check for this, therefore a lot of useless calls to
has_sha1_file() and parse_object() were made before discovering that
nothing needs to be done.

This patch adds the SEEN flag which is used in process() to make it
look at each object only once.  When testing git-local-fetch on the
repository of GIT, this gives a 14x improvement in CPU usage (mainly
because the redundant calls to parse_object() are now avoided -
parse_object() always unpacks and parses the object data, even if it
was already parsed before).

In all places where process() is called except the one in pull() (which
is executed only once) the pointer to the object is already available,
so pass it as the argument to process() instead of sha1 and avoid an
unneeded call to lookup_object_type().

This patch makes git-daemon --verbose log some useful things on stderr -
in particular connects, disconnects and upload requests, and in such a
way to be able to trace a particular session. Some more errors are now
also logged (even when --verbose is not passed). It is still not perfect
since messages produced by the non-daemon-specific code are obviously
not formatted properly.

git-export was done as a concept example on how easy it is to export
the git data to something else. It's much less powerful than any
number of trivial one-liner scripts now, and real exporters would not
ever use git-export.

It's obviously much less powerful than "git-whatchanged", or just
about any combination of git-rev-list + git-diff-tree.

We generate the ASCII representation of our internal date representation
("seconds since 1970, UTC + timezone information") in two different
places.

One of them uses the stupid and obvious way to make sure that it gets the
sexagecimal representation right for negative timezones even if they might
not be exact hours, and the other one depends on the modulus operator
always matching the sign of argument.

Hey, the clever one works. And C90 even specifies that behaviour. But I
had to think about it for a while when I was re-visiting this area, and
even if I didn't have to, it's kind of strange to have two different ways
to print out the same data format.

So use a common helper for this. And select the stupid and straighforward
way.
