Convert hashtable usage over to khash
This updates khash.h with some extra features (like error checking
on allocations, ability to use wrapped malloc, foreach calls, etc),
creates two high-level wrappers around khash: `git_khash_str` and
`git_khash_oid` for string-to-void-ptr and oid-to-void-ptr tables,
then converts all of the old usage of `git_hashtable` over to use
these new hashtables.
For `git_khash_str`, I've tried to create a set of macros that
yield an API not too unlike the old `git_hashtable` API. Since
the oid hashtable is only used in one file, I haven't bother to
set up all those macros and just use the khash APIs directly for
now.

Add git_reference_lookup_oid and lookup_resolved
Adds a new public reference function `git_reference_lookup_oid`
that directly resolved a reference name to an OID without returning
the intermediate `git_reference` object (hence, no free needed).
Internally, this adds a `git_reference_lookup_resolved` function
that combines looking up and resolving a reference. This allows
us to be more efficient with memory reallocation.
The existing `git_reference_lookup` and `git_reference_resolve`
are reimplmented on top of the new utility and a few places in the
code are changed to use one of the two new functions.

revwalk: use merge bases to speed up processing
There is no need walk down the parents of a merge base to mark them as
uninteresting because we'll never see them. Calculate the merge bases
in prepare_walk() so mark_uninteresting() can stop at a merge base
instead of walking all the way to the root.

revwalk: use a priority queue for calculating merge bases
As parents are older than their children, we're appending to the
commit list most of the time, which makes an ordered linked list quite
inefficient.
While we're there, don't sort the results list in the main loop, as
we're sorting them afterwards and it creates extra work.

Clean up GIT_UNUSED macros on all platforms
It turns out that commit 31e9cfc4cbcaf1b38cdd3dbe3282a8f57e5366a5
did not fix the GIT_USUSED behavior on all platforms. This commit
walks through and really cleans things up more thoroughly, getting
rid of the unnecessary stuff.
To remove the use of some GIT_UNUSED, I ended up adding a couple
of new iterators for hashtables that allow you to iterator just
over keys or just over values.
In making this change, I found a bug in the clar tests (where we
were doing *count++ but meant to do (*count)++ to increment the
value). I fixed that but then found the test failing because it
was not really using an empty repo. So, I took some of the code
that I wrote for iterator testing and moved it to clar_helpers.c,
then made use of that to make it easier to open fixtures on a
per test basis even within a single test file.

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.

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`

Rewrite the Revision Walker
The new revision walker uses an internal Commit object storage system,
custom memory allocator and much improved topological and time sorting
algorithms. It's about 20x times faster than the previous implementation
when browsing big repositories.
The following external API calls have changed:
`git_revwalk_next` returns an OID instead of a full commit object.
The initial call to `git_revwalk_next` is no longer blocking when
iterating through a repo with a time-sorting mode.
Iterating with Topological or inverted modes still makes the initial
call blocking to preprocess the commit list, but this block should be
mostly unnoticeable on most repositories (topological preprocessing
times at 0.3s on the git.git repo).
`git_revwalk_push` and `git_revwalk_hide` now take an OID instead
of a full commit object.

Rewrite git_hashtable internals
The old hash table with chained buckets has been replaced by a new one
using Cuckoo hashing, which offers guaranteed constant lookup times.
This should improve speeds on most use cases, since hash tables in
libgit2 are usually used as caches where the objects are stored once and
queried several times.
The Cuckoo hash implementation is based off the one in the Basekit
library [1] for the IO language, but rewritten to support an arbritrary
number of hashes. We currently use 3 to maximize the usage of the nodes pool.

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.

GIT_EXTERN(const char *) git_commit_message_short(git_commit *commit);
GIT_EXTERN(const char *) git_commit_message(git_commit *commit);
GIT_EXTERN(time_t) git_commit_time(git_commit *commit);
GIT_EXTERN(const git_commit_person *) git_commit_committer(git_commit *commit);
GIT_EXTERN(const git_commit_person *) git_commit_author(git_commit *commit);
GIT_EXTERN(const git_tree *) git_commit_tree(git_commit *commit);
A new structure, git_commit_person has been added to represent a
commit's author or committer.
The parsing of a commit has been split in two phases.
When adding a commit to the revision pool:
- the commit's ODB object is opened
- its raw contents are parsed for commit TIME, PARENTS and TREE
(the minimal amount of data required to traverse the pool)
- the commit's ODB object is closed
When querying for extended information on a commit:
- the commit's ODB object is reopened
- its raw contents are parsed for the requested information
- the commit's ODB object remains open to handle additional queries
New unit tests have been added for the new functionality:
In t0401-parse: parse_person_test
In t0402-details: query_details_test

Add support for tree objects in revision pools
Commits now store pointers to their tree objects.
Tree objects now work as separate git_revpool_object
entities.
Tree objects can be loaded and parsed inedependently
from commits.

Changed revpool's object table to support arbitrary objects
git_revpool_object now has a type identifier for each object
type in a revpool (commits, trees, blobs, etc).
Trees can now be stored in the revision pool.
git_revpool_tableit now supports filtering objects by their
type when iterating through the object table.

Fixed memory leaks in test suite
Created commit objects in t0401-parse weren't being freed properly.
Updated the API documentation to note that commit objects are owned
by the revision pool and should not be freed manually.
The parents list of each commit was being freed twice after each test.

Actually free all commits when freeing a commit pool
Previously the objects table was being freed, but not
the actuall commits. All git_commit objects are freed
and hence invalidated when freeing the git_rp object
they belong to.

Add object cache to the revision pool.
Fixed issue when generating pending commits list during iteration.
The 'git_commit_lookup' function will now check the pool's cache
for commits which have been previously loaded/parsed; there can only
be a single 'git_commit' structure for each commit on the same pool.

Add commit parents to parsed commits and commit lists to the revpool.
Basic support for iterating the revpool.
The following functions of the revwalk API have been partially
implemented:
void gitrp_reset(git_revpool *pool);
void gitrp_push(git_revpool *pool, git_commit *commit);
void gitrp_prepare_walk(git_revpool *pool);
git_commit *gitrp_next(git_revpool *pool);
Parsed commits' parents are now also parsed and stored in a
"git_commit_list" structure (linked list).

Add 'git_revpool_object' and 'git_revpool_table' structures.
All the objects which will will be eventually transversable from
a revision pool (commits, trees, etc) now inherit from the
'git_revpool_object' structure which identifies them with their
own OID.
Furthermore, the 'git_revpool_table' and related functions have
been added, which allow for constant time lookup (hash table)
of the loaded revpool objects based on their OID.

Wrap malloc and friends and report out of memory as GIT_ENOMEM
We now forbid direct use of malloc, strdup or calloc within the
library and instead use wrapper functions git__malloc, etc. to
invoke the underlying library malloc and set git_errno to a no
memory error code if the allocation fails.
In the future once we have pack objects in memory we are likely
to enhance these routines with garbage collection logic to purge
cached pack data when allocations fail. Because the size of the
function will grow somewhat large, we don't want to mark them for
inline as gcc tends to aggressively inline, creating larger than
expected executables.

s/git_revp/git_revpool/
git_revp is something I personally can't stop pronouncing
"rev pointer". I'm sure others would suffer the same
problem.
Also, rename the git_revp_ sub-api "gitrp_". This is the
first of many such renames, primarily done to prevent
extreme inflation in the "git_" namespace, which we'd like
to reserve for a higher-level API.
While we're at it, we remove the noise-char "c" from a lot
of functions. Since revision walking is all about commits,
the common case should be that we're dealing with commits.
Exceptions can get a more mnemonic description as needed.
