  Fix internal memory management on the library 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. Signed-off-by: Vicent Marti <tanoku@gmail.com>
