This commit modifies the dialog to present the most useful

gitk: Improve cherry-pick error handling
This adds to the regexps that are used to work out what sort of error
we encountered in trying to do a cherry-pick so that it recognizes
some additional common error messages. It adds a confirmation dialog
when the error is a merge conflict so the user can choose whether or
not to run git citool. Finally, it arranges to update the display
after a cherry-pick failed so that any local changes made by the
cherry-pick become visible.
Transient windows are always kept above their parent, and don't occupy
any space in the taskbar, which is useful for dialogs. Also, when
transient is used, it is important to bind windows to the correct
parent.
This commit adds transient annotations to all dialogs, ensures usage
of the correct parent for error and confirmation popups, and, as a

errors.

ModPerl::Registry precompiles scripts by wrapping them
in a subroutine. This causes ordinary subroutines of the
script to become nested, and warnings appear:
gitweb.cgi: Variable "$path_info" will not stay shared
This warning means that $path_info was declared as 'my',
and thus according to the perl evaluation rules all nested
subroutines will retain a reference to the instance of the
variable used in the first invocation of the master script.
When the script (i.e. the master meta-subroutine) is executed
the second time, it will use a new instance, so the logic
breaks. To avoid this it is necessary to declare all global
variables as 'our', which places them at the package level.

close another possibility for propagating pack corruption
Abstract
--------
With index v2 we have a per object CRC to allow quick and safe reuse of
pack data when repacking. This, however, doesn't currently prevent a
stealth corruption from being propagated into a new pack when _not_
reusing pack data as demonstrated by the modification to t5302 included
here.
The Context
-----------
The Git database is all checksummed with SHA1 hashes. Any kind of
corruption can be confirmed by verifying this per object hash against
corresponding data. However this can be costly to perform systematically
and therefore this check is often not performed at run time when
accessing the object database.
First, the loose object format is entirely compressed with zlib which
already provide a CRC verification of its own when inflating data. Any
disk corruption would be caught already in this case.
Then, packed objects are also compressed with zlib but only for their
actual payload. The object headers and delta base references are not
deflated for obvious performance reasons, however this leave them
vulnerable to potentially undetected disk corruptions. Object types
are often validated against the expected type when they're requested,
and deflated size must always match the size recorded in the object header,
so those cases are pretty much covered as well.
Where corruptions could go unnoticed is in the delta base reference.
Of course, in the OBJ_REF_DELTA case, the odds for a SHA1 reference to
get corrupted so it actually matches the SHA1 of another object with the
same size (the delta header stores the expected size of the base object
to apply against) are virtually zero. In the OBJ_OFS_DELTA case, the
reference is a pack offset which would have to match the start boundary
of a different base object but still with the same size, and although this
is relatively much more "probable" than in the OBJ_REF_DELTA case, the
probability is also about zero in absolute terms. Still, the possibility
exists as demonstrated in t5302 and is certainly greater than a SHA1
collision, especially in the OBJ_OFS_DELTA case which is now the default
when repacking.
Again, repacking by reusing existing pack data is OK since the per object
CRC provided by index v2 guards against any such corruptions. What t5302
failed to test is a full repack in such case.
The Solution
------------
As unlikely as this kind of stealth corruption can be in practice, it
certainly isn't acceptable to propagate it into a freshly created pack.
But, because this is so unlikely, we don't want to pay the run time cost
associated with extra validation checks all the time either. Furthermore,
consequences of such corruption in anything but repacking should be rather
visible, and even if it could be quite unpleasant, it still has far less
severe consequences than actively creating bad packs.
So the best compromize is to check packed object CRC when unpacking
objects, and only during the compression/writing phase of a repack, and
only when not streaming the result. The cost of this is minimal (less
than 1% CPU time), and visible only with a full repack.
Someone with a stats background could provide an objective evaluation of
this, but I suspect that it's bad RAM that has more potential for data
corruptions at this point, even in those cases where this extra check
is not performed. Still, it is best to prevent a known hole for
corruption when recreating object data into a new pack.
What about the streamed pack case? Well, any client receiving a pack
must always consider that pack as untrusty and perform full validation
anyway, hence no such stealth corruption could be propagated to remote
repositoryes already. It is therefore worthless doing local validation
in that case.

We used to have non-POSIX comformant BRE in our code, and linked with GNU
regexp library on a few platforms (Darwin, FreeBSD and AIX) to work it
around. This was backwards.
We've fixed the broken regexps to use ERE that native regexp libraries on
these platforms can handle just fine. There is no need to link with GNU
regexp library on these platforms anymore.

connect.c: add a way for git-daemon to pass an error back to client
The current behavior of git-daemon is to simply close the connection on
any error condition. This leaves the client without any information as
to the cause of the failed fetch/push/etc.
This patch allows get_remote_heads to accept a line prefixed with "ERR"
that it can display to the user in an informative fashion. Once clients
can understand this ERR line, git-daemon can be made to properly report
"repository not found", "permission denied", or other errors.
Example
S: ERR No matching repository.
C: fatal: remote error: No matching repository.

Introduce receive.denyDeletes
Occasionally, it may be useful to prevent branches from getting deleted from
a centralized repository, particularly when no administrative access to the
server is available to undo it via reflog. It also makes
receive.denyNonFastForwards more useful if it is used for access control
since it prevents force-updating by deleting and re-creating a ref.

fix overlapping memcpy in normalize_absolute_path
The comments for normalize_absolute_path explicitly claim
that the source and destination buffers may be the same
(though they may not otherwise overlap). Thus the call to
memcpy may involve copying overlapping data, and memmove
should be used instead.
This fixes a valgrind error in t1504.

pack-objects: avoid reading uninitalized data
In the main loop of find_deltas, we do:
struct object_entry *entry = *list++;
...
if (!*list_size)
...
break
Because we look at and increment *list _before_ the check of
list_size, in the very last iteration of the loop we will
look at uninitialized data, and increment the pointer beyond
one past the end of the allocated space. Since we don't
actually do anything with the data until after the check,
this is not a problem in practice.
But since it technically violates the C standard, and
because it provokes a spurious valgrind warning, let's just
move the initialization of entry to a safe place.
This fixes valgrind errors in t5300, t5301, t5302, t303, and
t9400.

correct cache_entry allocation
Most cache_entry structs are allocated by using the
cache_entry_size macro, which rounds the size of the struct
up to the nearest multiple of 8 bytes (presumably to avoid
memory fragmentation).
There is one exception: the special "conflict entry" is
allocated with an empty name, and so is explicitly given
just one extra byte to hold the NUL.
However, later code doesn't realize that this particular
struct has been allocated differently, and happily tries
reading and copying it based on the ce_size macro, which
assumes the 8-byte alignment.
This can lead to reading uninitalized data, though since
that data is simply padding, there shouldn't be any problem
as a result. Still, it makes sense to hold the padding
assumption so as not to surprise later maintainers.
This fixes valgrind errors in t1005, t3030, t4002, and
t4114.

git-gui: Do not munge conflict marker lines in a normal diff
Previously, conflict markers were highlighted in two ways: (1) They
received a distinguishing color; and (2) they had the '+' removed at the
beginning of the line. However, by doing (2), a hunk that contained
conflict markers could not be staged or unstaged because the resulting
patch was corrupted. With this change we no longer modify the diff text
of a 2-way diff, so that "Stage Hunk" and friends work.
Note that 3-way diff of a conflicted file is unaffected by this change,
and '++' before conflict markers is still removed. But this has no negative
impact because in this mode staging hunks or lines is disabled anyway.

git-gui: Add a simple implementation of SSH_ASKPASS.
OpenSSH allows specifying an external program to use
for direct user interaction. While most Linux systems
already have such programs, some environments, for
instance, msysgit, lack it. This patch adds a simple
fallback Tcl implementation of the tool.
In msysgit it is also necessary to set a fake value of
the DISPLAY variable, because otherwise ssh won't even
try to use SSH_ASKPASS handlers.

Generating a new SSH key or finding an existing one may
be a difficult task for non-technical users, especially
on Windows.
This commit adds a new dialog that shows the public key,
or allows the user to generate a new one if none were found.
Since this is a convenience/informational feature for new
users, and the dialog is mostly read-only, it is located
in the Help menu.
The command line used to invoke ssh-keygen is designed to
force it to use SSH_ASKPASS if available, or accept empty
passphrases, but _never_ wait for user response on the tty.
