All initialization functions now return error codes instead of pointers.
Error codes are now properly propagated on most functions. Several new
and more specific error codes have been added in common.h

String mememory is now managed in a much more sane manner.
Fixes include:
- git_person email and name is no longer limited to 64 characters
- git_tree_entry filename is no longer limited to 255 characters
- raw objects are properly opened & closed the minimum amount of
times required for parsing
- unit tests no longer leak
- removed 5 other misc memory leaks as reported by Valgrind
- tree writeback no longer segfaults on rare ocassions
The git_person struct is no longer public. It is now managed by the
library, and getter methods are in place to access its internal
attributes.

The tree array wasn't being initialized when instantiating a tree object
in memory instead of loading it from disk.
New unit tests added to check for the problem.

git_tree_entry_byname was dereferencing a NULL pointer when the searched
file couldn't be found on the tree.
New test cases have been added to check for entry access methods.

All the setter methods for git_tree have been added, including the
setters for attributes on each git_tree_entry and methods to add/remove
entries of the tree.
Modified trees and trees created in-memory from scratch can be written
back to the repository using git_object_write().

All repository objects can now be created from scratch in memory using
either the git_object_new() method, or the corresponding git_XXX_new()
for each object.
So far, only git_commits can be written back to disk once created in
memory.

The 'git_obj' structure is now called 'git_rawobj', since
it represents a raw object read from the ODB.
The 'git_repository_object' structure is now called 'git_object',
since it's the base object class for all objects.

git_repository_object has now several internal methods to write back the
object information in the repository.
- git_repository__dbo_prepare_write()
Prepares the DBO object to be modified
- git_repository__dbo_write()
Writes new bytes to the DBO object
- git_repository__dbo_writeback()
Writes back the changes to the repository

Some compilers give linking problems when exporting 'uint32_t' as a
return type in the external API. Use generic types instead.

The interface for loading and parsing tree objects from a repository has
been completed with all the required accesor methods for attributes,
support for manipulating individual tree entries and a new unit test
t0901-readtree which tries to load and parse a tree object from a
repository.

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.

revision pool can now be parsed and queried.

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.
