40721f6b12 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.

088a731f00 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.

58b0cbea74 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.

e5d1faefab Add external API for revision sorting.
The GIT_RPSORT_XXX flags have been moved to the external API,
and a new method 'gitrp_sorting(...)' has been added to safely
change the sorting method of a revision pool.

655d381a19 Add topological sorting and new insertion methods for commit lists.
'git_commit_list_toposort()' and 'git_commit_list_timesort()' now
sort a commit list by topological and time order respectively.
Both sorts are stable and in place.

'git_commit_list_append' has been replaced by 'git_commit_list_push_back'
and 'git_commit_list_push_front'.

a7c182c594 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.

c5696427b6 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.

8add015392 Split git_commit_lookup into separate functions.
git_commit_lookup() now creates commit references
without loading them from the ODB.

git_commit_parse() creates a commit reference, loads
it and parses it from the ODB.

08d5d00056 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).

64a47c0142 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.

1b9e92c73b 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.
