The motivation for mailmap.blob is to let users of bare
repositories use the mailmap feature, as they would not have
a checkout containing the .mailmap file. We can make it even
easier for them by just looking in HEAD:.mailmap by default.
We can't know for sure that this is where they would keep a
mailmap, of course, but it is the best guess (and it matches
the non-bare behavior, which reads from HEAD:.mailmap in the
working tree). If it's missing, git will silently ignore the
setting.
We do not do the same magic in the non-bare case, because:
1. In the common case, HEAD:.mailmap will be the same as
the .mailmap in the working tree, which is a no-op.
2. In the uncommon case, the user has modified .mailmap
but not yet committed it, and would expect the working
tree version to take precedence.

The error handling for the read_mailmap function is odd. It
returns 1 on error, rather than -1. And it treats a
non-existent mailmap as an error, even though there is no
reason that one needs to exist. Unless some other mailmap
source loads successfully, in which case the original error
is completely masked.
This does not cause any bugs, however, because no caller
bothers to check the return value, anyway. Let's make this a
little more robust to real errors and less surprising for
future callers that do check the error code:
1. Return -1 on errors.
2. Treat a missing entry (e.g., no mailmap.file given),
ENOENT, or a non-existent blob (for mailmap.blob) as
"no error".
3. Complain loudly when a real error (e.g., a transient
I/O error, no permission to open the mailmap file,
missing or corrupted blob object, etc) occurs.

In a bare repository, there isn't a simple way to respect an
in-tree mailmap without extracting it to a temporary file.
This patch provides a config variable, similar to
mailmap.file, which reads the mailmap from a blob in the
repository.

The read_single_mailmap function opens a mailmap file and
parses each line. In preparation for having non-file
mailmaps, let's pull out the line-parsing logic into its own
function (read_mailmap_line), and rename the file-parsing
function to match (read_mailmap_file).

AddressSanitizer (http://clang.llvm.org/docs/AddressSanitizer.html)
complains of a one-byte buffer underflow in parse_name_and_email() while
running the test suite. And indeed, if one of the lines in the mailmap
begins with '<', we dereference the address just before the beginning of
the buffer when looking for whitespace to remove, before checking that
we aren't going too far.
So reverse the order of the tests to make sure that we don't read
outside the buffer.

The callers of map_user() give email and name to it, and expect to get the
up-to-date email and/or name to be used in their output. The function
rewrites the given buffers in place. To optimize the majority of cases,
the function returns 0 when it did not do anything, and it returns 1 when
the caller should use the updated contents.
The 'email' input to the function is terminated by '>' or a NUL (whichever
comes first) for historical reasons, but when a rewrite happens, the value
is replaced with the mailbox inside the <> pair. However, it failed to
meet this expectation when it only rewrote the name part without rewriting
the email part, and the email in the input was terminated by '>'.
This causes an extra '>' to appear in the output of "blame -e", because the
caller does send in '>'-terminated email, and when the function returned 1
to tell it that rewriting happened, it appends '>' that is necessary when
the email part was rewritten.
The patch looks bigger than it actually is, because this change makes a
variable that points at the end of the email part in the input 'p' live
much longer than it used to, deserving a more descriptive name.
Noticed and diagnosed by Felipe Contreras and Jeff King.

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:

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.

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.

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.

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.
