Teach import-tars about GNU tar's @LongLink extension.
This extension allows GNU tar to process file names in excess of the 100
characters defined by the original tar standard. It does this by faking a
file, named '././@LongLink' containing the true file name, and then adding
the file with a truncated name. The idea is that tar without this
extension will write out a file with the long file name, and write the
contents into a file with truncated name.
Unfortunately, GNU tar does a lousy job at times. When truncating results
in a _directory_ name, it will happily use _that_ as a truncated name for
the file.
An example where this actually happens is gcc-4.1.2, where the full path
of the file WeThrowThisExceptionHelper.java truncates _exactly_ before the
basename. So, we have to support that ad-hoc extension.
This bug was noticed by Chris Riddoch on IRC.

git-gui: Track our own embedded values and rebuild when they change
Like core-Git we now track the values that we embed into our shell
script wrapper, and we "recompile" that wrapper if they are changed.
This concept was lifted from git.git's Makefile, where a similar
thing was done by Eygene Ryabinkin. Too bad it wasn't just done
here in git-gui from the beginning, as the git.git Makefile support
for GIT-GUI-VARS was really just because git-gui doesn't do it on
its own.

Whenever we want to execute a git subcommand from the plumbing
layer (and on rare occasion, the more porcelain-ish layer) we
tend to use our proc wrapper, just to make the code slightly
cleaner at the call sites. I wasn't doing that in a couple of
places, so this is a simple cleanup to correct that.

git-gui: Use option database defaults to set the font
Rather than passing "-font font_ui" to every widget that we
create we can instead reconfigure the option database for
all widget classes to use our font_ui as the default widget
font. This way Tk will automatically setup their defaults
for us, and we can reduce the size of the application.
Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
An earlier change tossed these optionMenu font configurations
all over the code, when really we can just rename the proc to
a hidden internal name and provide our own wrapper to install
the font configuration we really want.
We also don't need to set these option database entries in all
of the procedures that open dialogs; instead we should just set
one time, them after we have the font configuration ready for use.

git-gui: Correct line wrapping for too many branch message
Since Tk automatically wraps lines for us in tk_messageBox
widgets we don't need to try to wrap them ourselves. Its
actually worse that we linewrapped this here in the script,
as not all fonts will render this dialog nicely.

git-gui: Warn users before making an octopus merge
A coworker who was new to git-gui recently tried to make an octopus
merge when he did not quite mean to. Unfortunately in his case the
branches had file level conflicts and failed to merge with the octopus
strategy, and he didn't quite know why this happened. Since most users
really don't want to perform an octopus merge this additional safety
valve in front of the merge process is a good thing.

Fix symlink handling in git-svn, related to PerlIO
After reading the leading contents from a symlink data obtained
from subversion, which we expect to begin with 'link ', the code
forked to hash the remainder (which should match readlink()
result) using git-hash-objects, by redirecting its STDIN from
the filehandle we read that 'link ' from. This was Ok with Perl
on modern Linux, but on Mac OS, the read in the parent process
slurped more than we asked for in stdio buffer, and the child
did not correctly see the "remainder".
This attempts to fix the issue by using lower level sysseek and
sysread instead of seek and read to bypass the stdio buffer.

post-receive-email example hook: sed command for getting description was wrong
The sed command that extracted the first line of the project description
didn't include the -n switch and hence the project name was being
printed twice. This was ruining the email header generation because it
was assumed that the description was only one line and was included in
the subject. This turned the subject into a two line item and

Tim Ansell discovered his Debian server didn't permit git-daemon to
use as much memory as it needed to handle cloning a project with
a 128 MiB packfile. Filtering the strace provided by Tim of the
rev-list child showed this gem of a sequence:
open("./objects/pack/pack-*.pack", O_RDONLY|O_LARGEFILE <unfinished ...>
<... open resumed> ) = 5
And we asked for another window further into the file. But got
denied. In Tim's case this was due to a resource limit on the
git-daemon process, and its children.
Now where are we in the code? We're down inside use_pack(),
after we have called unuse_one_window() enough times to make sure
we stay within our allowed maximum window size. However since we
didn't unmap the prior window at 0xb5e2d000 we aren't exceeding
the current limit (which probably was just the defaults).
But we're actually down inside xmmap()...
So we release the window we do have (by calling release_pack_memory),
assuming there is some memory pressure...
And that was the last window in this packfile. So we closed it.
Way to go us. Our xmmap did not expect release_pack_memory to
close the fd its about to map...
And we report the bad file descriptor error, and not the ENOMEM,
and die, claiming we are out of memory. But actually that mmap
should have succeeded, as we had enough memory for that window,
seeing as how we released the prior one.
Originally when I developed the sliding window mmap feature I had
this exact same bug in fast-import, and I dealt with it by handing
in the struct packed_git* we want to open the new window for, as the
caller wasn't prepared to reopen the packfile if unuse_one_window
closed it. The same is true here from xmmap, but the caller doesn't
have the struct packed_git* handy. So I'm using the file descriptor
instead to perform the same test.

Create a sysconfdir variable, and use it for ETC_GITCONFIG
ETC_GITCONFIG defaults to $(prefix)/etc/gitconfig, so if you just set
prefix=/usr, you end up with a git that looks in /usr/etc/gitconfig, rather
than /etc/gitconfig as specified by the FHS. Furthermore, setting
ETC_GITCONFIG does not fix the paths to any future system-wide configuration
files.
Factor out the path to the system-wide configuration directory into a variable
sysconfdir, normally set to $(prefix)/etc, but set to /etc when prefix=/usr .
This fixes the prefix=/usr problem for ETC_GITCONFIG, and allows centralized
configuration of any future system-wide configuration files without requiring
further action from package maintainers or other people building and
installing git.
