object_type: GIT_OBJECT_BAD is now GIT_OBJECT_INVALID
We use the term "invalid" to refer to bad or malformed data, eg
`GIT_REF_INVALID` and `GIT_EINVALIDSPEC`. Since we're changing the
names of the `git_object_t`s in this release, update it to be
`GIT_OBJECT_INVALID` instead of `BAD`.

object: properly propagate errors on parsing failures
When failing to parse a raw object fromits data, we free the
partially parsed object but then fail to propagate the error to the
caller. This may lead callers to operate on objects with invalid memory,
which will sooner or later cause the program to segfault.
Fix the issue by passing up the error code returned by `parse_raw`.

object: implement function to parse raw data
Now that we have implement functions to parse all git objects from raw
data, we can implement a generic function `git_object__from_raw` to
create a structure of type `git_object`. This allows us to parse and
interpret objects from raw data without having to touch the ODB at all,
which is especially useful for object verification prior to accepting
them into the repository.

object: introduce git_object_stringn2type
Introduce an internal API to get the object type based on a
length-specified (not null terminated) string representation. This can
be used to compare the (space terminated) object type name in a loose
object.
Reimplement `git_object_string2type` based on this API.

Make sure to always include "common.h" first
Next to including several files, our "common.h" header also declares
various macros which are then used throughout the project. As such, we
have to make sure to always include this file first in all
implementation files. Otherwise, we might encounter problems or even
silent behavioural differences due to macros or defines not being
defined as they should be. So in fact, our header and implementation
files should make sure to always include "common.h" first.
This commit does so by establishing a common include pattern. Header
files inside of "src" will now always include "common.h" as its first
other file, separated by a newline from all the other includes to make
it stand out as special. There are two cases for the implementation
files. If they do have a matching header file, they will always include
this one first, leading to "common.h" being transitively included as
first file. If they do not have a matching header file, they instead
include "common.h" as first file themselves.
This fixes the outlined problems and will become our standard practice
for header and source files inside of the "src/" from now on.

settings: rename `GIT_OPT_ENABLE_SYNCHRONOUS_OBJECT_CREATION`
Initially, the setting has been solely used to enable the use of
`fsync()` when creating objects. Since then, the use has been extended
to also cover references and index files. As the option is not yet part
of any release, we can still correct this by renaming the option to
something more sensible, indicating not only correlation to objects.
This commit renames the option to `GIT_OPT_ENABLE_FSYNC_GITDIR`. We also
move the variable from the object to repository source code.

object: avoid call of memset with ouf of bounds pointer
When computing a short OID we do this by first copying the
leading parts into the new OID structure and then setting the
trailing part to zero. In the case of the desired length being
`GIT_OID_HEXSZ - 1` we will call `memset` with an out of bounds
pointer and a length of 0. While this seems to cause no problems
for common platforms the C89 standard does not explicitly state
that calling `memset` with an out of bounds pointer and
length of 0 is valid.
Fix the potential issue by using the newly introduced
`git_oid__cpy_prefix` function.

Revert "object: correct the expected ID size in prefix lookup"
This reverts commit 969d4b703c910a8fd045baafbcd243b4c9825316.
This was a fluke from Coverity. The length to all the APIs in the
library is supposed to be passed in as nibbles, not bytes. Passing it as
bytes would prevent us from parsing uneven-sized SHA1 strings.
Also, the rest of the library was still using nibbles (including
revparse and the odb_prefix APIs), so this change was seriously breaking
things in unexpected ways. ^^

object: correct the expected ID size in prefix lookup
We take in a possibly partial ID by taking a length and working off of
that to figure out whether to just look up the object or ask the
backends for a prefix lookup.
Unfortunately we've been checking the size against `GIT_OID_HEXSZ` which
is the size of a *string* containing a full ID, whereas we need to check
against the size we can have when it's a 20-byte array.
Change the checks and comment to use `GIT_OID_RAWSZ` which is the
correct size of a git_oid to have when full.

peel: reject bad queries with EINVALIDSPEC
There are some combination of objects and target types which we know
cannot be fulfilled. Return EINVALIDSPEC for those to signify that there
is a mismatch in the user-provided data and what the object model is
capable of satisfying.
If we start at a tag and in the course of peeling find out that we
cannot reach a particular type, we return EPEEL.

Add callback to git_objects_table
This adds create and free callback to the git_objects_table so
that more of the creation and destruction of objects can be table
driven instead of using switch statements. This also makes the
semantics of certain object creation functions consistent so that
we can make better use of function pointers. This also fixes a
theoretical error case where an object allocation fails and we
end up storing NULL into the cache.

Reorg internal odb read header and object lookup
Often `git_odb_read_header` will "fail" and have to read the
entire object into memory instead of just the header. When this
happens, the object is loaded and then disposed of immediately,
which makes it difficult to efficiently use the header information
to decide if the object should be loaded (since attempting to do
so will often result in loading the object twice).
This commit takes the existing code and reorganizes it to have
two new functions:
- `git_odb__read_header_or_object` which acts just like the old
read header function except that it returns the object, too, if
it was forced to load the whole thing. It then becomes the
callers responsibility to free the `git_odb_object`.
- `git_object__from_odb_object` which was extracted from the old
`git_object_lookup` and creates a subclass of `git_object` from
an existing `git_odb_object` (separating the ODB lookup from the
`git_object` creation). This allows you to use the first header
reading function efficiently without instantiating the
`git_odb_object` twice.
There is no net change to the behavior of any of the existing
functions, but this allows internal code to tap into the ODB
lookup and object creation to be more efficient.

Make git_object_peel a bit smarter
This expands the types of peeling that `git_object_peel` knows
how to do to include TAG -> BLOB peeling, and makes the errors
slightly more consistent depending on the situation. It also
adds a new special behavior where peeling to ANY will peel until
the object type changes (e.g. chases TAGs to a non-TAG).
Using this expanded peeling, this replaces peeling code that was
embedded in `git_tag_peel` and `git_reset`.

Support reading attributes from index
Depending on the operation, we need to consider gitattributes
in both the work dir and the index. This adds a parameter to
all of the gitattributes related functions that allows user
control of attribute reading behavior (i.e. prefer workdir,
prefer index, only use index).
This fix also covers allowing us to check attributes (and
hence do diff and status) on bare repositories.
This was a somewhat larger change that I hoped because it had
to change the cache key used for gitattributes files.

versions of map.c. There are some minor changes to other
files but no others were completely converted.
This also contains an update to filebuf so that a zeroed out
filebuf will not think that the fd (== 0) is actually open
(and inadvertently call close() on fd 0 if cleaned up).
Lastly, this was built and tested on win32 and contains a
bunch of fixes for the win32 build which was pretty broken.

repository: Change ownership semantics
The ownership semantics have been changed all over the library to be
consistent. There are no more "borrowed" or duplicated references.
Main changes:
- `git_repository_open2` and `3` have been dropped.
- Added setters and getters to hotswap all the repository owned
objects:
`git_repository_index`
`git_repository_set_index`
`git_repository_odb`
`git_repository_set_odb`
`git_repository_config`
`git_repository_set_config`
`git_repository_workdir`
`git_repository_set_workdir`
Now working directories/index files/ODBs and so on can be
hot-swapped after creating a repository and between operations.
- All these objects now have proper ownership semantics with
refcounting: they all require freeing after they are no longer
needed (the repository always keeps its internal reference).
- Repository open and initialization has been updated to keep in
mind the configuration files. Bare repositories are now always
detected, and a default config file is created on init.
- All the tests affected by these changes have been dropped from the
old test suite and ported to the new one.

Added git.git sha1 lookup method to replace simple binary search in pack backend.
Implemented find_unique_short_oid for pack backend, based on git sha1 lookup method;
finding an object given its full oid is just a particular case of searching
the unique object matching an oid prefix (short oid).
Added git_odb_read_unique_short_oid, which iterates over all the backends to
find and read the unique object matching the given oid prefix.
Added a git_object_lookup_short_oid method to find the unique object in
the repository matching a given oid prefix : it generalizes git_object_lookup
which now does nothing but calls git_object_lookup_short_oid.

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`:

-----
- Remove type `git_rawobj`
- Remove `git_rawobj_close`
- Rename `git_rawobj_hash` -> `git_odb_hash`
- Change `git_odb_hash`:

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`

git_object_lookup() should also check the type if the object comes from the cache

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.

Fix segmentation fault when freeing a repository
Disable garbage collection of cross-references to prevent
double-freeing. Internal reference management is now done
with a separate method.

Fix several issues with refcounting
- Added several missing reference increases
- Add new destructor to the repository that does not GC the objects

Change the object creation/lookup API
The methods previously known as
git_repository_lookup
git_repository_newobject
git_repository_lookup_ref
are now part of their respective namespaces:
git_object_lookup
git_object_new
git_reference_lookup
This makes the API more consistent with the new references API.

Implement reference counting for git_objects
All `git_object` instances looked up from the repository are reference
counted. User is expected to use the new `git_object_close` when an
object is no longer needed to force freeing it.
