Currently, libgit2 compiles and passes all tests under MinGW, and
compiles but fails the test suite on MSVC 2010.

The libgit2 shared library must be linked with all the dynamic libraries
it depends (z, openssl).

These libraries are now automatically detected during the configuration
phase.

Also, removed the linking dependency on libgit2 which Scott added: if
you link libgit2 with itself, the universe could implode, and we don't
want that to happen.

We cannot assume that non-bare repositories have an index file, because
'git index' doesn't create it by default.

Commit object must be internally free'd after each parse attempt, even
it fails.

Signed-off-by: Vicent Marti <tanoku@gmail.com>

The internal contents of the blob were being free'd but not the blob
object itself.

Actually add files to the index by creating their corresponding blob and
storing it on the repository, then getting the hash and updating the
index file.

Several private methods of the Index API are now public, including the
methods to remove, get and add index entries.

All the methods only take an integer value for the position of the entry
to get/remove. To get or remove entries based on their path names, look
them up first using the git_index_find method.

The constructor to git_repository is now called

	'git_repository_open(path)'

and takes a path to a git repository instead of an existing ODB object.
Unit tests have been updated accordingly and the two test repositories

Issue 9 on the tracker. The commit object getters for in-memory objects
were trying to parse an inexistant on-disk object when one of the commit
attributes which were still not set was queried.

We now return a NULL value when this happens.

Before changing the attributes of a commit, make sure that the internal
status is consistent with the one in the repository.

Test the new method by loading all the objects in the sample ODB with a
full-read and a header-only read, and comparing the types and sizes.

Signed-off-by: Vicent Marti <tanoku@gmail.com>

As requested, git_odb_read_header looks up an object on the ODB, but loads
only the header information (type & size) without loading any of the
actual file contents in memory.

It is significantly faster than doing a git_odb_read if you only need an
object's information and not its contents.

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.

In particular, msvc complains thus:

    t0603-sort.c(23) : warning C4244: 'function' : conversion from \
        'time_t' to 'unsigned int', possible loss of data

Note that msvc, by default, defines time_t as a 64-bit type, whereas
srand() is expecting an (32-bit) unsigned int. In order to suppress
the warning, we simply cast the return value of the time() function
call to 'unsigned int'.
