Johan Herland c56fcc89b9 Add flags to get_commit_notes() to control the format of the note string
This patch adds the following flags to get_commit_notes() for adjusting the
format of the produced note string:

Johannes Schindelin fd53c9eb44 Speed up git notes lookup
To avoid looking up each and every commit in the notes ref's tree
object, which is very expensive, speed things up by slurping the tree
object's contents into a hash_map.

The idea for the hashmap singleton is from David Reiss, initial
benchmarking by Jeff King.

Note: the implementation allows for arbitrary entries in the notes
tree object, ignoring those that do not reference a valid object.  This
allows you to annotate arbitrary branches, or objects.

This patch has been improved by the following contributions:
- Junio C Hamano: fixed an obvious error in initialize_hash_map()

Johannes Schindelin a97a74686d Introduce commit notes
Commit notes are blobs which are shown together with the commit
message.  These blobs are taken from the notes ref, which you can
configure by the config variable core.notesRef, which in turn can
be overridden by the environment variable GIT_NOTES_REF.

The notes ref is a branch which contains "files" whose names are
the names of the corresponding commits (i.e. the SHA-1).

The rationale for putting this information into a ref is this: we
want to be able to fetch and possibly union-merge the notes,
maybe even look at the date when a note was introduced, and we
want to store them efficiently together with the other objects.

This patch has been improved by the following contributions:
- Thomas Rast: fix core.notesRef documentation
- Tor Arne Vestbø: fix printing of multi-line notes
- Alex Riesen: Using char array instead of char pointer costs less BSS
- Johan Herland: Plug leak when msg is good, but msglen or type causes return

get_commit_notes(): Plug memory leak when 'if' triggers, but not because of read_sha1_file() failure

Tor Arne Vestbø 22a3d06093 git-notes: fix printing of multi-line notes
The line length was read from the same position every time,
causing mangled output when printing notes with multiple lines.

Also, adding new-line manually for each line ensures that we
get a new-line between commits, matching git-log for commits
without notes.
