Just like MISC_H (see previous commit), there is no reason to track
xdiff and vcs-svn headers separately from the rest of the headers.
The only purpose of these variables is to keep track of recompilation
dependencies.
As a pleasant side effect, folding these into LIB_H lets us stop
tracking GIT_OBJS and VCSSVN_TEST_OBJS separately from the list of all
OBJECTS.

Mac OS X mangles file names containing unicode on file systems HFS+,
VFAT or SAMBA. When a file using unicode code points outside ASCII
is created on a HFS+ drive, the file name is converted into
decomposed unicode and written to disk. No conversion is done if
the file name is already decomposed unicode.
Calling open("\xc3\x84", ...) with a precomposed "Ä" yields the same
result as open("\x41\xcc\x88",...) with a decomposed "Ä".
As a consequence, readdir() returns the file names in decomposed
unicode, even if the user expects precomposed unicode. Unlike on
HFS+, Mac OS X stores files on a VFAT drive (e.g. an USB drive) in
precomposed unicode, but readdir() still returns file names in
decomposed unicode. When a git repository is stored on a network
share using SAMBA, file names are send over the wire and written to
disk on the remote system in precomposed unicode, but Mac OS X
readdir() returns decomposed unicode to be compatible with its
behaviour on HFS+ and VFAT.
The unicode decomposition causes many problems:
- The names "git add" and other commands get from the end user may
often be precomposed form (the decomposed form is not easily input
from the keyboard), but when the commands read from the filesystem
to see what it is going to update the index with already is on the
filesystem, readdir() will give decomposed form, which is different.
- Similarly "git log", "git mv" and all other commands that need to
compare pathnames found on the command line (often but not always
precomposed form; a command line input resulting from globbing may
be in decomposed) with pathnames found in the tree objects (should
be precomposed form to be compatible with other systems and for
consistency in general).
- The same for names stored in the index, which should be
precomposed, that may need to be compared with the names read from
readdir().
NFS mounted from Linux is fully transparent and does not suffer from
the above.
As Mac OS X treats precomposed and decomposed file names as equal,
we can
- wrap readdir() on Mac OS X to return the precomposed form, and
- normalize decomposed form given from the command line also to the
precomposed form,
to ensure that all pathnames used in Git are always in the
precomposed form. This behaviour can be requested by setting
"core.precomposedunicode" configuration variable to true.
The code in compat/precomposed_utf8.c implements basically 4 new
functions: precomposed_utf8_opendir(), precomposed_utf8_readdir(),
precomposed_utf8_closedir() and precompose_argv(). The first three
are to wrap opendir(3), readdir(3), and closedir(3) functions.
The argv[] conversion allows to use the TAB filename completion done
by the shell on command line. It tolerates other tools which use
readdir() to feed decomposed file names into git.
When creating a new git repository with "git init" or "git clone",
"core.precomposedunicode" will be set "false".
The user needs to activate this feature manually. She typically
sets core.precomposedunicode to "true" on HFS and VFAT, or file
systems mounted via SAMBA.

Without this change, clang complains:

This code uses an old and common idiom for suppressing an
"uninitialized variable" warning, and clang is wrong to warn about it.
The idiom tells the compiler to leave the variable uninitialized,
which saves a few bytes of code size, and, more importantly, allows
valgrind to check at runtime that the variable is properly initialized
by the time it is used.
But MSVC and clang do not know that idiom, so let's avoid it in
vcs-svn/ code.
Initialize pre_off to -1, a recognizably meaningless value, to allow
future code changes that cause pre_off to be used before it is

When we see a signed-off-by line (and its friends), we set $signoff
to true, but then we process the next line after we are done without
giving control to the rest of the loop. And when the line we saw is
not a signed-off-by line, we reset $signoff to false before running
the remainder of the loop.
Hence, the check for $signoff that attempts to remove an extra empty
line between two signed-off-by line was not doing anything useful.
Rename $empty to a more explicit name $skip_blank_line to tell us to
skip a blank line when we see one, set it after we see and emit a
blank line (to avoid showing more than one empty lines in a raw) or
after we handle a signed-off-by line (to avoid empty lines after
such a line), to fix this bug, and get rid of the $signoff variable
that is not useful.

* hv/remote-end-hung-up:
remove the impression of unexpectedness when access is denied
When we try to push a ref and the right-hand side of the
refspec does not find a match, we try to create it. If it is
not fully qualified, we try to guess where it would go in
the refs hierarchy based on the left-hand source side. If
the source side is not a ref, then we give up and give a
long explanatory message.
For deletions, however, this doesn't make any sense. We
would never want to create on the remote side, and if an
unqualified ref can't be matched, it is simply an error. The
current code handles this already because the left-hand side
is empty, and therefore does not give us a hint as to where
the right-hand side should go, and we properly error out.
Unfortunately, the error message is the long "we tried to
qualify this, but the source side didn't let us guess"
message, which is quite confusing.
Instead, we can just be more succinct and say "we can't
delete this because we couldn't find it". So before:
$ git push origin :bogus
error: unable to push to unqualified destination: bogus
The destination refspec neither matches an existing ref on the remote nor
begins with refs/, and we are unable to guess a prefix based on the source ref.
error: failed to push some refs to '$URL'
and now:
$ git push origin :bogus
error: unable to delete 'bogus': remote ref does not exist
error: failed to push some refs to '$URL'
It is tempting to also catch a fully-qualified ref like
"refs/heads/bogus" and generate the same error message.
However, that currently does not error out at all, and
instead gets sent to the remote side, which typically
generates a warning:
$ git push origin:refs/heads/bogus
remote: warning: Deleting a non-existent ref.
To $URL
- [deleted] bogus
While it would be nice to catch this error early, a
client-side error would mean aborting the push entirely and
changing push's exit code. For example, right now you can
do:
$ git push origin refs/heads/foo refs/heads/bar
and end up in a state where "foo" and "bar" are deleted,
whether both of them currently exist or not (and see an
error only if we actually failed to contact the server).
Generating an error would cause a regression for this use
case.

In finish_object_disambiguation(), if the candidate hasn't been
checked, there are two cases:
- It is the first and only object that match the prefix; or
- It replaced another object that matched the prefix but that
object did not satisfy ds->fn() callback.
And the former case we set ds->candidate_ok to true without doing
anything else, while for the latter we check the candidate, which
may set ds->candidate_ok to false.
At this point in the code, ds->candidate_ok can be false only if
this last-round check found that the candidate does not pass the
check, because the state after update_candidates() returns cannot
satisfy
!ds->ambiguous && ds->candidate_exists && ds->candidate_checked
and !ds->canidate_ok at the same time.
Hence, when we execute this "return", we know we have seen more than
one object that match the prefix (and none of them satisfied ds->fn),
meaning that we should say "the short name is ambiguous", not "there
is no object that matches the prefix".

We try to find zero, one or more matches from loose objects and
packed objects independently and then decide if the given short
object name is unique across them.
Instead, introduce a "struct disambiguate_state" that keeps track of
what we have found so far, that can be one of:
- We have seen one object that _could_ be what we are looking for;
- We have also checked that object for additional constraints (if any),
and found that the object satisfies it;
- We have also checked that object for additional constraints (if any),
and found that the object does not satisfy it; or
- We have seen more than one objects that satisfy the constraints.
and pass it to the enumeration functions for loose and packed
objects. The disambiguation state can optionally take a callback
function that takes a candidate object name and reports if the
object satisifies additional criteria (e.g. when the caller knows
that the short name must refer to a commit, this mechanism can be
used to check the type of the given object).
Compared to the earlier attempt, this round avoids the optional
check if there is only one candidate that matches the short name in
the first place.
