Read and write each 1024 byte buffer, rather than trying to buffer
the entire content of the file. We are only copying the contents to
a file descriptor and do not use it ourselves.
Previous code would crash on all files > 2 Gib, when the offset
variable became negative (perhaps below the level of perl),
resulting in a crash. On a 32 bit system, or a system with low
memory it might crash before reaching 2 GiB due to memory
exhaustion.
This code may leave a partial file behind in case of failure, where
the old code would leave a completely empty file. Neither version
verifies the correctness of the content. Calling code must take
care of verification and cleanup.

When passed a local time that was on the boundary of a DST change,
get_tz_offset returned a GMT offset that was incorrect (off by one
hour). This is because the time was converted to GMT and then back to
a time stamp via timelocal() which cannot disambiguate boundary cases
as noted in its documentation.
Modify this algorithm, using an approach suggested in
http://article.gmane.org/gmane.comp.version-control.git/213871
to first convert the timestamp in question to two broken down forms
with localtime() and gmtime(), and then compute what timestamps
these two broken down forms would represent in GMT (i.e. a timezone
that does not have DST issues) by applying timegm() on them. The
difference between the resulting timestamps is the timezone offset.
This avoids the ambigious conversion and allows a correct time to be
returned on every occassion.

When command_input_pipe and command_output_pipe are used as a
method of a Git::repository instance, they eventually call into
_cmd_exec method that sets up the execution environment such as
GIT_DIR, GIT_WORK_TREE environment variables and the current
working directory in the child process that interacts with the
repository.
command_bidi_pipe however didn't expect to be called as such, and
lacked all these set-up. Because of this, a program that did this
did not work as expected:
my $repo = Git->repository(Directory => '/some/where/else');
my ($pid, $in, $out, $ctx) =
$repo->command_bidi_pipe(qw(hash-object -w --stdin-paths));
This patch refactors the _cmd_exec into _setup_git_cmd_env that
sets up the execution environment, and makes _cmd_exec and
command_bidi_pipe to use it.
Note that unlike _cmd_exec that execv's a git command as an
external process, command_bidi_pipe is called from the main line
of control, and the execution environment needs to be restored
after open2() does its magic.

Formalize our dependency on perl 5.8, bumped from 5.6.[12]. We already
used the three-arg form of open() which was introduced in 5.6.1, but
t/t9700/test.pl explicitly depended on 5.6.2.
However git-add--interactive.pl has been failing on the 5.6 line since
it was introduced in v1.5.0-rc0~12^2~2 back in 2006 due to this open
syntax:
sub run_cmd_pipe {
my $fh = undef;
open($fh, '-|', @_) or die;
return <$fh>;
}
Which when executed dies on "Can't use an undefined value as
filehandle reference". Several of our tests also fail on 5.6 (even
more when compiled with NO_PERL_MAKEMAKER=1):
t2016-checkout-patch.sh
t3904-stash-patch.sh
t3701-add-interactive.sh
t7105-reset-patch.sh
t7501-commit.sh
t9700-perl-git.sh
Our code is bitrotting on 5.6 with no-one interested in fixing it, and
pinning us to such an ancient release of Perl is keeping us from using
useful features introduced in the 5.8 release.
The 5.6 series is now over 10 years old, and the 5.6.2 maintenance
release almost 7. 5.8 on the other hand is more than 8 years old.
All the modern Unix-like operating systems have now upgraded to it or
a later version, and 5.8 packages are available for old IRIX, AIX
Solaris and Tru64 systems.

Before commit d3c9634e, performing a "git svn rebase" that fetched a
change containing CRLFs corrupted the git-svn meta-data. This was
worked around in d3c9634e by setting core.autocrlf to "false" in the
per-repo config when initing the clone. However, if the config
variable was later changed, the corruption would still occur.
This patch tries to fix it while allowing core.autocrlf to be
enabled, by disabling filters when when hashing.
git-svn is currently the only call-site for hash_and_insert_object
(apart from the test-suite), so changing it should be safe.

Update the usage of File::Temp->tempfile to place the temporary files
within the repository directory instead of just letting Perl decide what
directory to use, given there is a repository specified when requesting
the temporary file.
This is needed to be able to fix git-svn on msys as msysperl generates
paths with UNIX-style paths (/tmp/xxx) while the git tools expect natvie
path format (c:/..). The repository dir is stored in native format so by
using it as the base directory for temporary files we always get a
usable native full path.

This patch offers a generic interface to allow temp files to be
cached while using an instance of the 'Git' package. If many
temp files are created and destroyed during the execution of a
program, this caching mechanism can help reduce the amount of
files created and destroyed by the filesystem.
The temp_acquire method provides a weak guarantee that a temp
file will not be stolen by subsequent requests. If a file is
locked when another acquire request is made, a simple error is
thrown.

This is mostly lifted from earlier series by Dan Zwell, but updated to
use "git config --get-color" and "git config --get-colorbool" to make it
simpler and more consistent with commands written in C.
A new configuration color.interactive variable is like color.diff and
color.status, and controls if "git-add -i" uses color.
A set of configuration variables, color.interactive.<slot>, are used to
define what color is used for the prompt, header, and help text.
For perl scripts, Git.pm provides $repo->get_color() method, which takes
the slot name and the default color, and returns the terminal escape
sequence to color the output text. $repo->get_colorbool() method can be
used to check if color is set to be used for a given operation.
