merge-recursive: options to ignore whitespace changes

Add support for merging with ignoring line endings (specifically
--ignore-space-at-eol) when using recursive merging. This is
as a strategy-option, so that you can do:

git merge --strategy-option=ignore-space-at-eol <branch>

and

git rebase --strategy-option=ignore-space-at-eol <branch>

This can be useful for coping with line-ending damage (Xcode 3.1 has a
nasty habit of converting all CRLFs to LFs, and VC6 tends to just use
CRLFs for inserted lines).

The only option I need is ignore-space-at-eol, but while at it,
include the other xdiff whitespace options (ignore-space-change,
ignore-all-space), too.

merge-recursive --patience

Teach the merge-recursive strategy a --patience option to use the
"patience diff" algorithm, which tends to improve results when
cherry-picking a patch that reorders functions at the same time as
refactoring them.

To support this, struct merge_options and ll_merge_options gain an
xdl_opts member, so programs can use arbitrary xdiff flags (think
"XDF_IGNORE_WHITESPACE") in a git-aware merge.

git merge and git rebase can be passed the -Xpatience option to
use this.

merge-recursive --renormalize

Teach "git merge-recursive" a --renormalize option to enable the
merge.renormalize configuration. The --no-renormalize option can
be used to override it in the negative.

So in the future, you might be able to, e.g.:

git checkout -m -Xrenormalize otherbranch

or

git revert -Xrenormalize otherpatch

or

git pull --rebase -Xrenormalize

The bad part: merge.renormalize is still not honored for most
commands. And it reveals lots of places that -X has not been plumbed
in (so we get "git merge -Xrenormalize" but not much else).

rerere: never renormalize

plain rerere performs three tasks; let us consider how the new
merge.renormalize option should apply to each.

After an unsuccessful merge, rerere records conflict hunks from the
work tree under .git/rr-cache. If the merge was performed with
merge.renormalize enabled, both sides of the conflict hunk use the
current work tree’s end-of-line and smudge rules; there is not really
much of a choice.

After a successful manual resolution, rerere records the postimage.
Here, also, the file will be in the current work tree’s canonical
format and there is not much to do about it.

When encountering that conflict again, merge looks up the preimage
and postimage using the conflict hunk as a key and runs a three-way
merge to apply that resolution to the work tree. Since the conflict
hunk used the current work tree’s canonical format, chances are the
version in the work tree, the preimage, and the postimage will, too.
In fact using the merge.renormalize machinery is exactly the wrong
thing to do, since its result has been run through convert_to_git
and therefore is not suitable for writing to the work tree.

The only affected caller is "git merge".

- omit whitespace after >redirection operators for
consistency with other tests;

- use "update-index --refresh" instead of testing that
"ls-files -u" output is empty, since the former produces

ll-merge: make flag easier to populate

ll_merge() takes its options in a flag word, which has a few
advantages:

- options flags can be cheaply passed around in registers, while
an option struct passed by pointer cannot;

- callers can easily pass 0 without trouble for no options,
while an option struct passed by value would not allow that.

The downside is that code to populate and access the flag word can be
somewhat opaque. Mitigate that with a few macros.

merge-trees: push choice to renormalize away from low level

The merge machinery decides whether to resmudge and clean relevant
entries based on the global merge_renormalize setting, which is set by
"git merge" based on its configuration (and left alone by other
commands).

A nicer interface would make that decision a parameter to merge_trees
so callers would pass in a choice made on a call-by-call basis.
Start by making blob_unchanged stop examining the merge_renormalize
global.

Try normalizing files to avoid delete/modify conflicts when merging

If a file is modified due to normalization on one branch, and deleted on
another, a merge of the two branches will result in a delete/modify
conflict for that file even if it is otherwise unchanged.

Try to avoid the conflict by normalizing and comparing the "base" file
and the modified file when their sha1s differ. If they compare equal,
the file is considered unmodified and is deleted.

Avoid conflicts when merging branches with mixed normalization

Currently, merging across changes in line ending normalization is
painful since files containing CRLF will conflict with normalized files,
even if the only difference between the two versions is the line
endings. Additionally, any "real" merge conflicts that exist are
obscured because every line in the file has a conflict.

Assume you start out with a repo that has a lot of text files with CRLF
checked in (A):

o---C
/ \
A---B---D

B: Add "* text=auto" to .gitattributes and normalize all files to
LF-only

C: Modify some of the text files

D: Try to merge C

You will get a ridiculous number of LF/CRLF conflicts when trying to
merge C into D, since the repository contents for C are "wrong" wrt the
new .gitattributes file.

Fix ll-merge so that the "base", "theirs" and "ours" stages are passed
through convert_to_worktree() and convert_to_git() before a three-way
merge. This ensures that all three stages are normalized in the same
way, removing from consideration differences that are only due to
normalization.

This feature is optional for now since it changes a low-level mechanism
and is not necessary for the majority of users. The "merge.renormalize"
config variable enables it.

git-cvsserver: fix error for invalid password formats

Change the error message to report the erroneous password
character. $1 was never set in the previos version, it was a leftover
from older code that used a regex for the test.

textconv: support for cat_file

Make the textconv_object function public, and add --textconv option to cat-file
to perform conversion on blob objects. Using --textconv implies that we are
working on a blob.
As files drivers need to be initialized, a new config is required in addition
to git_default_config. Therefore git_cat_file_config() is introduced
