Implement a pack indexer

git_status_foreach issue

signature.c: fix off-by-one error

git_signature_new() and git_signature_now() currently don't return error
codes. Change the API to return error codes and not pointers to let the
user handle errors properly.

You can use it just as you'd use a for-loop

The callers immediately throw away the offset, so we don't need any
logical changes in any of them. This will be useful for the indexer,
as it does need to know where the compressed data ends.

This code is useful for more things than just the packfile handling
code. Factor it out so it can be reused.

Header fix for C++ and double include in git2.h

Don't stat so much when reading references

Remove extra git_index_read from the tests

Fixup network headers

Including git2/status.h in the git2.h header.

The network headers were still missing some formalities.

On some header files, GIT_END_DECL was absent while GIT_BEGIN_DECL wasn't

When you open an index with git_index_open, the file is read before
the function returns. Thus, calling git_index_read after that is
useless.

z_stream.next_in is non-const. Although currently Zlib doesn't modify
buffer content on deflate(), it might be change in the future. gzwrite()
already modify it.

To avoid this let's change signature of git_filebuf.write and rework
git_filebuf_write() accordingly.

index_init_entry() renamed to index_entry_init(). Now it allocates entry
on its own.

git_index_add() and git_index_append() reworked accordingly.

This commit fixes warning:
