Added new global configuration variable @diff_opts, which holds
additional options (parameters) to git-diff and git-diff-tree, usually
dealing rename/copying detection. Default value is '-M', taken from
git_commit subroutine. Description of options and their approximate
cost by Junio C Hamano.
Changes:
* git_commitdiff, git_blobdiff and git_blobdiff_plain now use '-M'
instead of '-M', '-C'
* git-diff now uses the same options as git-diff-tree
* git_comittdiff_plain now uses '-M' instead of '-B'
and is now rename-aware
* git_rss uses now '-M' instead of ()

I noticed that I was looking at the kernel gitweb output at some point
rather than just do "git log", simply because I liked seeing the
simplified date-format, ie the "5 days ago" rather than a full date.
This adds infrastructure to do that for "git log" too. It does NOT add the
actual flag to enable it, though, so right now this patch is a no-op, but
it should now be easy to add a command line flag (and possibly a config
file option) to just turn on the "relative" date format.
The exact cut-off points when it switches from days to weeks etc are
totally arbitrary, but are picked somewhat to avoid the "1 weeks ago"
thing (by making it show "10 days ago" rather than "1 week", or "70
minutes ago" rather than "1 hour ago").

In the Windows world ZIP files are better supported than tar files.
Windows even includes built-in support for ZIP files nowadays.
git-zip-tree is similar to git-tar-tree; it creates ZIP files out of
git trees. It stores the commit ID (if available) in a ZIP file comment
which can be extracted by unzip.
There's still quite some room for improvement: this initial version
supports no symlinks, calls write() way too often (three times per file)
and there is no unit test.

Change unpack_entry_gently and its helper functions to use offsets
rather than addresses and left counts to supply pack position
information. In most cases this makes the code easier to follow,

It also better prepares this code for mapping partial segments of

an entry.

If we're always incrementing both the offset and the pointer we
aren't gaining anything by keeping both. Instead just use the

This is second part of removing gitweb dependency on external
diff (used in git_diff_print).
Get rid of git_diff_print invocation in git_blobdiff, and use either
git-diff-tree (when both hash_base and hash_parent_base are provided)
patch format or git-diff patch format (when only hash and hash_parent
are provided) for output.
Supported URI schemes, and output formats:
* New URI scheme: both hash_base and hash_parent_base (trees-ish
containing blobs versions we want to compare) are provided.
Also either filename is provided, or hash (of blob) is provided
(we try to find filename then).
For this scheme we have copying and renames detection, mode changes,
file types etc., and information extended diff header is correct.
* Old URI scheme: hash_parent_base is not provided, we use hash and
hash_parent to directly compare blobs using git-diff. If no filename
is given, blobs hashes are used in place of filenames.
This scheme has always "blob" as file type, it cannot detect mode
changes, and we rely on CGI parameters to provide name of the file.
Added git_to_hash subroutine, which transforms symbolic name or list
of symbolic name to hash or list of hashes using git-rev-parse.
To have "blob" instead of "unknown" (or "file" regardless of the type)
in "gitweb diff header" for legacy scheme, file_type function now
returns its argument if it is not octal string.
Added support for fake "2" status code in git_patchset_body. Such code
is generated by git_blobdiff in legacy scheme case.
ATTENTION: The order of arguments (operands) to git-diff is reversed
(sic!) to have correct diff in the legacy (no hash_parent_base) case.
$hash_parent, $hash ordering is commented out, as it gives reversed
patch (at least for git version 1.4.1.1) as compared to output in new
scheme and output of older gitweb version.

we can put hyperlinks there. This makes possible to do blobdiff with
only blobs hashes.
The lines in two-line unified diff header have now class "from_file"

"rem" and "add" because of '-' and '+' as first character of patch
line).

Get rid of git_diff_print invocation in git_commitdiff and therefore
external diff (/usr/bin/diff) invocation, and use only git-diff-tree
to generate patch.
git_commitdiff and git_commitdiff_plain are collapsed into one
subroutine git_commitdiff, with format (currently 'html' which is
default format corresponding to git_commitdiff, and 'plain'
corresponding to git_commitdiff_plain) specified in argument.
Separate patch (diff) pretty-printing into git_patchset_body.
It is used in git_commitdiff.
Separate patch (diff) line formatting from git_diff_print into
format_diff_line function. It is used in git_patchset_body.
While at it, add $hash parameter to git_difftree_body, according to
rule that inner functions should use parameter passing, and not global
variables.
CHANGES TO OUTPUT:
* "commitdiff" now products patches with renaming and copying
detection (git-diff-tree is invoked with -M and -C options).
Empty patches (mode changes and pure renames and copying)
are not written currently. Former version broke renaming and
copying, and didn't notice mode changes, like this version.
* "commitdiff" output is now divided into several div elements
of class "log", "patchset" and "patch".
* "commitdiff_plain" now only generates X-Git-Tag: line only if there
is tag pointing to the current commit. Former version which wrote
first tag following current commit was broken[*1*]; besides we are
interested rather in tags _preceding_ the commit, and _heads_
following the commit. X-Git-Url: now is current URL; former version
tried[*2*] to output URL to HTML version of commitdiff.
* "commitdiff_plain" is generated by git-diff-tree, and has therefore
has git specific extensions to diff format: "git diff" header and
optional extended header lines.
FOOTNOTES
[*1*] First it generated rev-list starting from HEAD even if hash_base
parameter was set, second it wasn't corrected according to changes
made in git_get_references (formerly read_info_ref) output, third even
for older version of read_info_ref output it didn't work for multiple
tags pointing to the current commit (rare).
[*2*] It wrote URL for commitdiff without hash_parent, which produces
diff to first parent and is not the same as current diff if it is diff
of merge commit to non-first parent.
