Documentation: prepare to be consistent about "git-" versus "git "
With the dashed forms of git commands not in $(bindir), we have

for consistency it is at times appropriate to make the opposite
change. In some cases, the change is not so simple as changing one
character.

git-svn: avoid filling up the disk with temp files.
Commit ffe256f9bac8a40ff751a9341a5869d98f72c285 ("git-svn: Speed up fetch")
introduced changes that create a temporary file for each object fetched by
svn. These files should be deleted automatically, but perl apparently
doesn't do this until the process exits (or perhaps when its garbage
collector runs).
This means that on a large fetch, especially with lots of branches, we
sometimes fill up /tmp completely, which prevents the next temp file from
being written completely. This is aggravated by the fact that a new temp
file is created for each updated file, even if that update produces a file
identical to one already in git. Thus, it can happen even if there's lots
of disk space to store the finished repository.
We weren't adequately checking for write errors, so this would result in an
invalid file getting committed, which caused git-svn to fail later with an
invalid checksum.
This patch adds a check to syswrite() so similar problems don't lead to
corruption in the future. It also unlink()'s each temp file explicitly
when we're done with it, so the disk doesn't need to fill up.

Allow "git-reset path" when unambiguous
Resetting a selected set of index entries is done with

This updates the command to follow the general rule:
* When -- appears, revs come before it, and paths come after it;
* When there is no --, earlier ones are revs and the rest are paths, and
we need to guess. When lack of -- marker forces us to guess, we
protect from user errors and typoes by making sure what we treat as
revs do not appear as filenames in the work tree, and what we treat as
paths do appear as filenames in the work tree, and by erroring out if
that is not the case. We tell the user to disambiguate by using -- in
such a case.
which is employed elsewhere in the system.
When this rule is applied to "reset", because we can have only zero or one
rev to the command, the check can be slightly simpler than other programs.
We have to check only the first one or two tokens after the command name
and options, and when they are:
-- A:
no explicit rev given; "A" and whatever follows it are paths.
A --:
explicit rev "A" given and whatever follows the "--" are paths.
A B:
"A" could be rev or path and we need to guess. "B" could
be missing but if exists that (and everything that follows) would
be paths.
So we apply the guess only in the last case and only to "A" (not "B" and
what comes after it).
* As long as "A" is unambiguously a path, index entries for "A", "B" (and
everything that follows) are reset to the HEAD revision.
* If "A" is unambiguously a rev, on the other hand, the index entries for
"B" (and everything that follows) are reset to the "A" revision.

Keep some git-* programs in $(bindir)
Otherwise remote executions directly over ssh won't find them as they used
to. --upload-pack and --receive-pack options _could_ be used on the
client side, but things should keep working out-of-box for older clients.
Later versions of clients (fetch-pack and send-pack) probably could start
asking for these programs with dashless form, but that is a different
topic.

Ship sample hooks with .sample suffix
We used to mark hooks we ship as samples by making them unexecutable, but
some filesystems cannot tell what is executable and what is not.
This makes it much more explicit. The hooks are suffixed with .sample
(but now are made executable), so enabling it is still one step operation
(instead of "chmod +x $hook", you would do "mv $hook.sample $hook") but
now they won't get accidentally enabled on systems without executable bit.

refactor pack structure allocation
New pack structures are currently allocated in 2 different places
and all members have to be initialized explicitly. This is prone
to errors leading to segmentation faults as found by Teemu Likonen.
Let's have a common place where this structure is allocated, and have
all members explicitly initialized to zero.

Prepare execv_git_cmd() for removal of builtins from the filesystem
Currently, execv_git_cmd() always try running the dashed form, which
means we cannot easily remove the git-foo hardlinks for built-in
commands. This updates the function to always exec "git foo" form, and
makes sure "git" potty does not infinitely recurse to itself.

implement some resilience against pack corruptions
We should be able to fall back to loose objects or alternative packs when
a pack becomes corrupted. This is especially true when an object exists
in one pack only as a delta but its base object is corrupted. Currently
there is no way to retrieve the former object even if the later is
available in another pack or loose.
This patch allows for a delta to be resolved (with a performance cost)
using a base object from a source other than the pack where that delta
is located. Same thing for non-delta objects: rather than failing
outright, a search is made in other packs or used loose when the
currently active pack has it but corrupted.
Of course git will become extremely noisy with error messages when that
happens. However, if the operation succeeds nevertheless, a simple
'git repack -a -f -d' will "fix" the corrupted repository given that all
corrupted objects have a good duplicate somewhere in the object store,
possibly manually copied from another source.
