mailmap: clean up read_mailmap error handling
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.

mailmap: clean up read_mailmap error handling
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.

mailmap: default mailmap.blob in bare repositories
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.

mailmap: remove email copy and length limitation
In map_user(), we have email pointer that points at the beginning of
an e-mail address, but the buffer is not terminated with a NUL after
the e-mail address. It typically has ">" after the address, and it
could have even more if it comes from author/committer line in a
commit object. Or it may not have ">" after it.
We used to copy the e-mail address proper into a temporary buffer
before asking the string-list API to find the e-mail address in the
mailmap, because string_list_lookup() function only takes a NUL
terminated full string.
Introduce a helper function lookup_prefix that takes the email
pointer and the length, and finds a matching entry in the string
list used for the mailmap, by doing the following:
- First ask string_list_find_insert_index() where in its sorted
list the e-mail address we have (including the possible trailing
junk ">...") would be inserted.
- It could find an exact match (e.g. we had a clean e-mail address
without any trailing junk). We can return the item in that case.
- Or it could return the index of an item that sorts after the
e-mail address we have.
- If we did not find an exact match against a clean e-mail address,
then the record we are looking for in the mailmap has to exist
before the index returned by the function (i.e. "email>junk"
always sorts later than "email"). Iterate, starting from that
index, down the map->items[] array until we find the exact record
we are looking for, or we see a record with a key that definitely
sorts earlier than the e-mail we are looking for (i.e. when we
are looking for "email" in "email>junk", a record in the mailmap
that begins with "emaik" strictly sorts before "email", if such a
key existed in the mailmap).
This, together with the earlier enhancement to support
case-insensitive sorting, allow us to remove an extra copy of email
buffer to downcase it.
A part of this is based on Antoine Pelisse's previous work.
