fast-import: Fix incorrect fanout level when modifying existing notes refs

This fixes the bug uncovered by the tests added in the previous two patches.

When an existing notes ref was loaded into the fast-import machinery, the
num_notes counter associated with that ref remained == 0, even though the
true number of notes in the loaded ref was higher. This caused a fanout
level of 0 to be used, although the actual fanout of the tree could be > 0.
Manipulating the notes tree at an incorrect fanout level causes removals to
silently fail, and modifications of existing notes to instead produce an
additional note (leaving the old object in place at a different fanout level).

This patch fixes the bug by explicitly counting the number of notes in the
notes tree whenever it looks like the num_notes counter could be wrong (when
num_notes == 0). There may be false positives (i.e. triggering the counting
when the notes tree is truly empty), but in those cases, the counting should
not take long.

t9301: Fix testcase covering up a bug in fast-import's notes fanout handling

There is a bug in fast-import where the fanout levels of an existing notes
tree being loaded into the fast-import machinery is disregarded. Instead, any
tree loaded is assumed to have a fanout level of 0. If the true fanout level
is deeper, any attempt to remove a note from that tree will silently fail
(as the note will not be found at fanout level 0).

However, this bug was covered up by the way in which the t9301 testcase was
written: When generating the fast-import commands to test mass removal of
notes, we appended these commands to an already existing 'input' file which
happened to already contain the fast-import commands used in the previous
subtest to generate the very same notes tree. This would normally be harmless
(but suboptimal) as the notes created were identical to the notes already
present in the notes tree. But the act of repeating all the notes additions
caused the internal fast-import data structures to recalculate the fanout,
instead of hanging on to the initial (incorrect) fanout (that causes the bug
described above). Thus, the subsequent removal of notes in the same 'input'
file would succeed, thereby covering up the bug described above.

This patch creates a new 'input' file instead of appending to the file from
the previous subtest. Thus, we end up properly testing removal of notes that
were added by a previous fast-import command. As a side effect, the notes
removal can no longer refer to commits using the marks set by the previous
fast-import run, instead the commits names must be referenced directly.

The underlying fast-import bug is still present after this patch, but now we
have at least uncovered it. Therefore, the affected subtests are labeled as
expected failures until the underlying bug is fixed.

on success due to an accident.  cherry-pick --abort is designed to

 2) call "git reset --merge <commit>" to move to that commit
 3) remove the .git/sequencer directory

.git/sequencer directory as a secondary effect --- after moving to
<commit>, or so the logic goes, it is unlikely but possible that the
caller of git reset wants to continue the series of cherry-picks that
was in progress, so git renames the sequencer state to
.git/sequencer-old to be helpful while allowing the cherry-pick to be
resumed if the caller did not want to end the sequence after all.

archive: don't let remote clients get unreachable commits

Usually git is careful not to allow clients to fetch
arbitrary objects from the database; for example, objects
received via upload-pack must be reachable from a ref.
Upload-archive breaks this by feeding the client's tree-ish
directly to get_sha1, which will accept arbitrary hex sha1s,
reflogs, etc.

This is not a problem if all of your objects are publicly
reachable anyway (or at least public to anybody who can run
upload-archive). Or if you are making the repo available by
dumb protocols like http or rsync (in which case the client
can read your whole object db directly).

But for sites which allow access only through smart
protocols, clients may be able to fetch trees from commits
that exist in the server's object database but are not
referenced (e.g., because history was rewound).

This patch tightens upload-archive's lookup to use dwim_ref
rather than get_sha1. This means a remote client can only
fetch the tip of a named ref, not an arbitrary sha1 or
reflog entry.

This also restricts some legitimate requests, too:

  1. Reachable non-tip commits, like:

        git archive --remote=$url v1.0~5

  2. Sub-trees of reachable commits, like:

        git archive --remote=$url v1.7.7:Documentation

Local requests continue to use get_sha1, and are not
restricted at all.

config.c: Fix a static buffer overwrite bug by avoiding mkpath()

On cygwin, test number 21 of t3200-branch.sh (git branch -m q q2
without config should succeed) fails. The failure involves the
functions from path.c which parcel out internal static buffers
from the git_path() and mkpath() functions.

In particular, the rename_ref() function calls safe_create_leading\
_directories() with a filename returned by git_path("logs/%s", ref).
safe_create_leading_directories(), in turn, calls stat() on each
element of the path it is given. On cygwin, this leads to a call
to git_config() for each component of the path, since this test
explicitly removes the config file. git_config() calls mkpath(), so
on the fourth component of the path, the original buffer passed
into the function is overwritten with the config filename.

Note that this bug is specific to cygwin and it's schizophrenic
stat() functions (see commits adbc0b67faee6b and 7974843). The
lack of a config file and a path with at least four elements is
also important to trigger the bug.

In order to fix the problem, we replace the call to mkpath() with
a call to mksnpath() and provide our own buffer.

Makefile: add option to disable automatic dependency generation

2011-08-18), there is no easy way to force it off.  For example,
setting COMPUTE_HEADER_DEPENDENCIES to the empty string in config.mak
just tells the makefile to treat it as undefined and run a test
command to see if the -MMD option is supported.

So allow setting COMPUTE_HEADER_DEPENDENCIES=no to explicitly force
the feature off.  The new semantics:

 - "yes" means to explicitly enable the feature
 - "no" means to disable it
 - "auto" means to autodetect

The default is still "auto".  Any value other than these three will
cause the build to error out with a descriptive message so typos and
stale settings in config.mak don't result in mysterious behavior.

Makefile:1278: *** please set COMPUTE_HEADER_DEPENDENCIES to
yes, no, or auto (not "1").  Stop.

So now when someone using a compiler without -MMD support reports
trouble building git, you can reproduce it by running "make
COMPUTE_HEADER_DEPENDENCIES=no".
