Fix tag and signature parsing
Before this commit, malformed tag and signature were considered as
valid by the parser. See the test t3800-mktag.sh of git to see example
of malformed tag and signature.

I broke your bindings
Hey. Apologies in advance -- I broke your bindings.
This is a major commit that includes a long-overdue redesign of the
whole object-database structure. This is expected to be the last major
external API redesign of the library until the first non-alpha release.
Please get your bindings up to date with these changes. They will be
included in the next minor release. Sorry again!
Major features include:
- Real caching and refcounting on parsed objects
- Real caching and refcounting on objects read from the ODB
- Streaming writes & reads from the ODB
- Single-method writes for all object types
- The external API is now partially thread-safe
The speed increases are significant in all aspects, specially when
reading an object several times from the ODB (revwalking) and when
writing big objects to the ODB.
Here's a full changelog for the external API:
blob.h
------
- Remove `git_blob_new`
- Remove `git_blob_set_rawcontent`
- Remove `git_blob_set_rawcontent_fromfile`
- Rename `git_blob_writefile` -> `git_blob_create_fromfile`
- Change `git_blob_create_fromfile`:
The `path` argument is now relative to the repository's working dir
- Add `git_blob_create_frombuffer`
commit.h
--------
- Remove `git_commit_new`
- Remove `git_commit_add_parent`
- Remove `git_commit_set_message`
- Remove `git_commit_set_committer`
- Remove `git_commit_set_author`
- Remove `git_commit_set_tree`
- Add `git_commit_create`
- Add `git_commit_create_v`
- Add `git_commit_create_o`
- Add `git_commit_create_ov`
tag.h
-----
- Remove `git_tag_new`
- Remove `git_tag_set_target`
- Remove `git_tag_set_name`
- Remove `git_tag_set_tagger`
- Remove `git_tag_set_message`
- Add `git_tag_create`
- Add `git_tag_create_o`
tree.h
------
- Change `git_tree_entry_2object`:
New signature is `(git_object **object_out, git_repository *repo, git_tree_entry *entry)`
- Remove `git_tree_new`
- Remove `git_tree_add_entry`
- Remove `git_tree_remove_entry_byindex`
- Remove `git_tree_remove_entry_byname`
- Remove `git_tree_clearentries`
- Remove `git_tree_entry_set_id`
- Remove `git_tree_entry_set_name`
- Remove `git_tree_entry_set_attributes`
object.h
------------
- Remove `git_object_new
- Remove `git_object_write`
- Change `git_object_close`:
This method is now *mandatory*. Not closing an object causes a
memory leak.
odb.h
-----
- Remove type `git_rawobj`
- Remove `git_rawobj_close`
- Rename `git_rawobj_hash` -> `git_odb_hash`
- Change `git_odb_hash`:
New signature is `(git_oid *id, const void *data, size_t len, git_otype type)`
- Add type `git_odb_object`
- Add `git_odb_object_close`
- Change `git_odb_read`:
New signature is `(git_odb_object **out, git_odb *db, const git_oid *id)`
- Change `git_odb_read_header`:
New signature is `(size_t *len_p, git_otype *type_p, git_odb *db, const git_oid *id)`
- Remove `git_odb_write`
- Add `git_odb_open_wstream`
- Add `git_odb_open_rstream`
odb_backend.h
-------------
- Change type `git_odb_backend`:
New internal signatures are as follows
int (* read)(void **, size_t *, git_otype *, struct git_odb_backend *, const git_oid *)
int (* read_header)(size_t *, git_otype *, struct git_odb_backend *, const git_oid *)
int (* writestream)(struct git_odb_stream **, struct git_odb_backend *, size_t, git_otype)
int (* readstream)( struct git_odb_stream **, struct git_odb_backend *, const git_oid *)
- Add type `git_odb_stream`
- Add enum `git_odb_streammode`

Fix the retarded object interdependency system
It's no longer retarded. All object interdependencies are stored as OIDs
instead of actual objects. This should be hundreds of times faster,
specially on big repositories. Heck, who knows, maye it doesn't even
segfault -- wouldn't that be awesome?
What has changed on the API?
`git_commit_parent`, `git_commit_tree`, `git_tag_target` now return
their values through a pointer-to-pointer, and have an error code.
`git_commit_set_tree` and `git_tag_set_target` now return an error
code and may fail.
`git_repository_free__no_gc` has been deprecated because it's
stupid. Since there are no longer any interdependencies between
objects, we don't need internal reference counting, and GC
never fails or double-free's pointers.
`git_object_close` now does a very sane thing: marks an object
as unused. Closed objects will be eventually free'd from the
object cache based on LRU. Please use `git_object_close` from
the garbage collector `destroy` method on your bindings. It's
100% safe.
`git_repository_gc` is a new method that forces a garbage collector
pass through the repo, to free as many LRU objects as possible.
This is useful if we are running out of memory.

- removed 5 other misc memory leaks as reported by Valgrind
- tree writeback no longer segfaults on rare ocassions

attributes.

Redesigned the walking/object lookup interface
The old 'git_revpool' object has been removed and
split into two distinct objects with separate
functionality, in order to have separate methods for
object management and object walking.
* A new object 'git_repository' does the high-level
management of a repository's objects (commits, trees,
tags, etc) on top of a 'git_odb'.
Eventually, it will also manage other repository
attributes (e.g. tag resolution, references, etc).
See: src/git/repository.h
* A new external method
'git_repository_lookup(repo, oid, type)'
has been added to the 'git_repository' API.
All object lookups (git_XXX_lookup()) are now
wrappers to this method, and duplicated code
has been removed. The method does automatic type
checking and returns a generic 'git_revpool_object'
that can be cast to any specific object.
See: src/git/repository.h
* The external methods for object parsing of repository
objects (git_XXX_parse()) have been removed.
Loading objects from the repository is now managed
through the 'lookup' functions. These objects are
loaded with minimal information, and the relevant
parsing is done automatically when the user requests
any of the parsed attributes through accessor methods.
An attribute has been added to 'git_repository' in
order to force the parsing of all the repository objects
immediately after lookup.
See: src/git/commit.h
See: src/git/tag.h
See: src/git/tree.h
* The previous walking functionality of the revpool
is now found in 'git_revwalk', which does the actual
revision walking on a repository; the attributes
when walking through commits in a database have been
decoupled from the actual commit objects.
This increases performance when accessing commits
during the walk and allows to have several
'git_revwalk' instances working at the same time on
top of the same repository, without having to load
commits in memory several times.
See: src/git/revwalk.h
* The old 'git_revpool_table' has been renamed to
'git_hashtable' and now works as a generic hashtable
with support for any kind of object and custom hash
functions.
See: src/hashtable.h
* All the relevant unit tests have been updated, renamed
and grouped accordingly.
