revwalk: don't try to find merge bases when there can be none
As a way to speed up the cases where we need to hide some commits, we
find out what the merge bases are so we know to stop marking commits as
uninteresting and avoid walking down a potentially very large amount of
commits which we will never see. There are however two oversights in
current code.
The merge-base finding algorithm fails to recognize that if it is only
given one commit, there can be no merge base. It instead walks down the
whole ancestor chain needlessly. Make it return an empty list
immediately in this situation.
The revwalk does not know whether the user has asked to hide any commits
at all. In situation where the user pushes multiple commits but doesn't
hide any, the above fix wouldn't do the trick. Keep track of whether the
user wants to hide any commits and only run the merge-base finding
algorithm when it's needed.

Convert pqueue to just be a git_vector
This updates the git_pqueue to simply be a set of specialized
init/insert/pop functions on a git_vector.
To preserve the pqueue feature of having a fixed size heap, I
converted the "sorted" field in git_vectors to a more general
"flags" field so that pqueue could mix in it's own flag. This
had a bunch of ramifications because a number of places were
directly looking at the vector "sorted" field - I added a couple
new git_vector helpers (is_sorted, set_sorted) so the specific
representation of this information could be abstracted.

Replace pqueue with code from hashsig heap
I accidentally wrote a separate priority queue implementation when
I was working on file rename detection as part of the file hash
signature calculation code. To simplify licensing terms, I just
adapted that to a general purpose priority queue and replace the
old priority queue implementation that was borrowed from elsewhere.
This also removes parts of the COPYING document that no longer
apply to libgit2.

Remove converting user error to GIT_EUSER
This changes the behavior of callbacks so that the callback error
code is not converted into GIT_EUSER and instead we propagate the
return value through to the caller. Instead of using the
giterr_capture and giterr_restore functions, we now rely on all
functions to pass back the return value from a callback.
To avoid having a return value with no error message, the user
can call the public giterr_set_str or some such function to set
an error message. There is a new helper 'giterr_set_callback'
that functions can invoke after making a callback which ensures
that some error message was set in case the callback did not set
one.
In places where the sign of the callback return value is
meaningful (e.g. positive to skip, negative to abort), only the
negative values are returned back to the caller, obviously, since
the other values allow for continuing the loop.
The hardest parts of this were in the checkout code where positive
return values were overloaded as meaningful values for checkout.
I fixed this by adding an output parameter to many of the internal
checkout functions and removing the overload. This added some
code, but it is probably a better implementation.
There is some funkiness in the network code where user provided
callbacks could be returning a positive or a negative value and
we want to rely on that to cancel the loop. There are still a
couple places where an user error might get turned into GIT_EUSER
there, I think, though none exercised by the tests.

Further EUSER and error propagation fixes
This continues auditing all the places where GIT_EUSER is being
returned and making sure to clear any existing error using the
new giterr_user_cancel helper. As a result, places that relied
on intercepting GIT_EUSER but having the old error preserved also
needed to be cleaned up to correctly stash and then retrieve the
actual error.
Additionally, as I encountered places where error codes were not
being propagated correctly, I tried to fix them up. A number of
those fixes are included in the this commit as well.

Remove regex usage from places that don't need it
In revwalk, we are doing a very simple check to see if a string
contains wildcard characters, so a full regular expression match
is not needed.
In remote listing, now that we have git_config_foreach_match with
full regular expression matching, we can take advantage of that
and eliminate the regex here, replacing it with much simpler string
manipulation.

Diff iterators
This refactors the diff output code so that an iterator object
can be used to traverse and generate the diffs, instead of just
the `foreach()` style with callbacks. The code has been rearranged
so that the two styles can still share most functions.
This also replaces `GIT_REVWALKOVER` with `GIT_ITEROVER` and uses
that as a common error code for marking the end of iteration when
using a iterator style of object.

really reset walker with git_revwalk_reset
From the description of git_revwalk_reset in revwalk.h the function should
clear all pushed and hidden commits, and leave the walker in a blank state (just like at creation).
Apparently everything gets reseted appart of pushed commits (walk->one and walk->twos)
This fix should reset the walker properly.

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 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.

There is no need walk down the parents of a merge base to mark them as

instead of walking all the way to the root.

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:

- 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`

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.

Add external API to access detailed commit attributes
The following new external methods have been added:
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
