d8d2eb7d6b mailmap: fix use of freed memory
On an x86_64 system (F13-based), I ran these commands in an empty directory:

    git init
    printf '%s\n' \
      '<jdoe@example.com> <jdoe@example.COM>' \
      'John <jdoe@example.com>' > .mailmap
    git shortlog < /dev/null

Here's the result:

    (reading log message from standard input)
    *** glibc detected *** git: free(): invalid pointer: 0x0000000000f53730 ***
    ======= Backtrace: =========
    /lib64/libc.so.6[0x31ba875676]
    git[0x48c2a5]
    git[0x4b9858]
    ...
    zsh: abort (core dumped)  git shortlog

What happened?

Some .mailmap entry is of the <email1> <email2> form,
while a subsequent one looks like "User Name <Email2>,
and the two email addresses on the right are not identical
but are "equal" when using a case-insensitive comparator.

Then, when add_mapping is processing the latter line, new_email is NULL
and we free me->email, yet do not replace it with a new strdup'd string.
Thus, when later we attempt to use the buffer behind that ->email pointer,
we reference freed memory.

The solution is to free ->email and ->name only if we're about to replace them.

[jc: squashed in the tests from Jonathan]

2af202be3d Fix various sparse warnings in the git source code
There are a few remaining ones, but this fixes the trivial ones. It boils
down to two main issues that sparse complains about:

 - warning: Using plain integer as NULL pointer

   Sparse doesn't like you using '0' instead of 'NULL'. For various good
   reasons, not the least of which is just the visual confusion. A NULL
   pointer is not an integer, and that whole "0 works as NULL" is a
   historical accident and not very pretty.

   A few of these remain: zlib is a total mess, and Z_NULL is just a 0.
   I didn't touch those.

 - warning: symbol 'xyz' was not declared. Should it be static?

   Sparse wants to see declarations for any functions you export. A lack
   of a declaration tends to mean that you should either add one, or you
   should mark the function 'static' to show that it's in file scope.

   A few of these remain: I only did the ones that should obviously just
   be made static.

That 'wt_status_submodule_summary' one is debatable. It has a few related
flags (like 'wt_status_use_color') which _are_ declared, and are used by
builtin-commit.c. So maybe we'd like to export it at some point, but it's
not declared now, and not used outside of that file, so 'static' it is in
this patch.

5288dd5835 Mailmap: Allow empty email addresses to be mapped
While it makes no sense to map some email address to an empty one, doing
things the other way around can be useful. For example when using
filter-branch with an env-filter that employs a mailmap to fix up an
import that created such broken commits with empty email addresses.

bf637803a7 mailmap: resurrect lower-casing of email addresses
Commit 0925ce4(Add map_user() and clear_mailmap() to mailmap) broke the
lower-casing of email addresses.  This mostly did not matter if your
.mailmap has only lower-case email addresses;  However, we did not
require .mailmap to contain lowercase-only email addresses.

0925ce4d49 Add map_user() and clear_mailmap() to mailmap
map_user() allows to lookup and replace both email and
name of a user, based on a new style mailmap file.

The possible mailmap definitions are now:

  proper_name <commit_email>                             # Old style
  <proper_email> <commit_email>                          # New style
  proper_name <proper_email> <commit_email>              # New style
  proper_name <proper_email> commit_name <commit_email>  # New style

map_email() operates the same as before, with the
exception that it also will to try to match on a name
passed in through the name return buffer.

clear_mailmap() is needed to now clear the more complex
mailmap structure.

d551a48816 Add mailmap.file as configurational option for mailmap location
This allows us to augment the repo mailmap file, and to use
mailmap files elsewhere than the repository root. Meaning
that the entries in mailmap.file will override the entries
in "./.mailmap", should they match.

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.
