delta-apply: fix sign extension
We compute offsets by executing `off |= (*delta++ << 24)` for
multiple constants, where `off` is of type `size_t` and `delta`
is of type `unsigned char`. The usual arithmetic conversions (see
ISO C89 §3.2.1.5 "Usual arithmetic conversions") kick in here,
causing us to promote both operands to `int` and then extending
the result to an `unsigned long` when OR'ing it with `off`.
The integer promotion to `int` may result in wrong size
calculations for big values.
Fix the issue by making the constants `unsigned long`, causing both
operands to be promoted to `unsigned long`.

odb: avoid inflating the full delta to read the header
When we read the header, we want to know the size and type of the
object. We're currently inflating the full delta in order to read the
first few bytes. This can mean hundreds of kB needlessly inflated for
large objects.
Instead use a packfile stream to read just enough so we can read the two
varints in the header and avoid inflating most of the delta.

Make our overflow check look more like gcc/clang's
Make our overflow checking look more like gcc and clang's, so that
we can substitute it out with the compiler instrinsics on platforms
that support it. This means dropping the ability to pass `NULL` as
an out parameter.
As a result, the macros also get updated to reflect this as well.

Tabify everything
There were quite a few places were spaces were being used instead of
tabs. Try to catch them all. This should hopefully not break anything.
Except for `git blame`. Oh well.

Cleanup legal data
1. The license header is technically not valid if it doesn't have a
copyright signature.
2. The COPYING file has been updated with the different licenses used in
the project.
3. The full GPLv2 header in each file annoys me.

Give object structures more descriptive names
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.

Fix a sparse "symbol not declared" warning
In particular, the git__delta_apply() function has not been
declared prior to it's definition. In order to suppress the
warning, include the delta-apply.h header which provides the
public interface. This ensures that the declaration and
definition are consistent.
