c455c87c5c Rename path_list to string_list
The name path_list was correct for the first usage of that data structure,
but it really is a general-purpose string list.

$ perl -i -pe 's/path-list/string-list/g' $(git grep -l path-list)
$ perl -i -pe 's/path_list/string_list/g' $(git grep -l path_list)
$ git mv path-list.h string-list.h
$ git mv path-list.c string-list.c
$ perl -i -pe 's/has_path/has_string/g' $(git grep -l has_path)
$ perl -i -pe 's/path/string/g' string-list.[ch]
$ git mv Documentation/technical/api-path-list.txt \
	Documentation/technical/api-string-list.txt
$ perl -i -pe 's/strdup_paths/strdup_strings/g' $(git grep -l strdup_paths)

... and then fix all users of string-list to access the member "string"
instead of "path".

Documentation/technical/api-string-list.txt needed some rewrapping, too.

03db4525d3 Support gitlinks in fast-import.
Currently fast-import/export cannot be used for
repositories with submodules. This patch extends
the relevant programs to make them correctly
process gitlinks.

Links can be represented by two forms of the
Modify command:

M 160000 SHA1 some/path

which sets the link target explicitly, or

M 160000 :mark some/path

where the mark refers to a commit. The latter
form can be used by importing tools to build
all submodules simultaneously in one physical
repository, and then simply fetch them apart.

1b1dd23f2d Make usage strings dash-less
When you misuse a git command, you are shown the usage string.
But this is currently shown in the dashed form.  So if you just
copy what you see, it will not work, when the dashed form
is no longer supported.

This patch makes git commands show the dash-less version.

For shell scripts that do not specify OPTIONS_SPEC, git-sh-setup.sh
generates a dash-less usage string now.

6e1c23442a Fix some warnings (on cygwin) to allow -Werror
When printing valuds of type uint32_t, we should use PRIu32, and should
not assume that it is unsigned int.  On 32-bit platforms, it could be
defined as unsigned long. The same caution applies to ntohl().

6991357513 fast-export --export-marks: fix off by one error
The export_marks() function iterated over a (potentially sparsely
populated) hashtable, but it accessed it starting from offset 1 and one
element beyond the end.

Noticed by SungHyun Nam.

df6a7ff7ac builtin-fast-export: Add importing and exporting of revision marks
This adds the --import-marks and --export-marks to fast-export. These import
and export the marks used to for all revisions exported in a similar fashion
to what fast-import does. The format is the same as fast-import, so you can
create a bidirectional importer / exporter by using the same marks file on
both sides.

d8933f013a fast-export: Correctly generate initial commits with no parents
If we are exporting a commit which has no parents we may be doing
it to a branch that already exists, causing fast-import to assume
the branch's current revision should be the sole parent of the
new commit.  This can cause `git fast-export | git fast-import`
to produce an incorrect graph for:

   A-------M----o------o  refs/heads/master
          /
       B-+

In this graph A and B are initial commits (no parents) but if A was
output first to refs/heads/master and then B is output fast-import
would assume the graph was this instead:

   A-------M----o------o  refs/heads/master
    \     /
     +-B-+

Which would cause B, M, and all later commits to have a different
SHA-1, and obviously be quite a different graph.

Sending a reset command prior to B informs fast-import to clear
the implied parent of A, allowing B to remain an initial commit.

5070b49e52 builtin-fast-export: Only output a single parent per line
According to the git-fast-import man-page, you can only put a single
committish per merge: line, like this:

  merge :10
  merge :11

However, git-fast-export puts all parents on a single line, like this:

  merge :10 :11

This changes fast-export to output a single parent per line.  Otherwise
neither git-fast-import nor bzr-fast-import can read its output.

[jc: fix-up to remove excess LF in the output that makes fast-import barf]

ef90d6d420 Provide git_config with a callback-data parameter
git_config() only had a function parameter, but no callback data
parameter.  This assumes that all callback functions only modify
global variables.

With this patch, every callback gets a void * parameter, and it is hoped
that this will help the libification effort.

8e0f70033b Avoid unnecessary "if-before-free" tests.
This change removes all obvious useless if-before-free tests.
E.g., it replaces code like this:

        if (some_expression)
                free (some_expression);

with the now-equivalent:

        free (some_expression);

It is equivalent not just because POSIX has required free(NULL)
to work for a long time, but simply because it has worked for
so long that no reasonable porting target fails the test.
Here's some evidence from nearly 1.5 years ago:

    http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html

FYI, the change below was prepared by running the following:

  git ls-files -z | xargs -0 \
  perl -0x3b -pi -e \
    's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s'

Note however, that it doesn't handle brace-enclosed blocks like
"if (x) { free (x); }".  But that's ok, since there were none like
that in git sources.

Beware: if you do use the above snippet, note that it can
produce syntactically invalid C code.  That happens when the
affected "if"-statement has a matching "else".
E.g., it would transform this

  if (x)
    free (x);
  else
    foo ();

into this:

  free (x);
  else
    foo ();

There were none of those here, either.

If you're interested in automating detection of the useless
tests, you might like the useless-if-before-free script in gnulib:
[it *does* detect brace-enclosed free statements, and has a --name=S
 option to make it detect free-like functions with different names]

  http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free

Addendum:
  Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

f2dc849e9c Add 'git fast-export', the sister of 'git fast-import'
This program dumps (parts of) a git repository in the format that
fast-import understands.

For clarity's sake, it does not use the 'inline' method of specifying
blobs in the commits, but builds the blobs before building the commits.

Since signed tags' signatures will not necessarily be valid (think
transformations after the export, or excluding revisions, changing
the history), there are 4 modes to handle them: abort (default),
ignore, warn and strip.  The latter just turns the tags into
unsigned ones.
