pack: add git_packfile_resolve_header
To paraphrase @peff:
You can get both size and type from a packed object reasonably cheaply.
If you have:
* An object that is not a delta; both type and size are available in the
packfile header.
* An object that is a delta. The packfile type will be OBJ_*_DELTA, and
you have to resolve back to the base to find the real type. That means
potentially a lot of packfile index lookups, but each one is
relatively cheap. For the size, you inflate the first few bytes of the
delta, whose header will tell you the resulting size of applying the
delta to the base.
For simplicity, we just decompress the whole delta for now.

Make git_odb_foreach_cb take const param
This makes the first OID param of the ODB callback a const pointer
and also propogates that change all the way to the backends.

Update iterators for consistency across library
This updates all the `foreach()` type functions across the library
that take callbacks from the user to have a consistent behavior.
The rules are:
* A callback terminates the loop by returning any non-zero value
* Once the callback returns non-zero, it will not be called again
(i.e. the loop stops all iteration regardless of state)
* If the callback returns non-zero, the parent fn returns GIT_EUSER
* Although the parent returns GIT_EUSER, no error will be set in
the library and `giterr_last()` will return NULL if called.
This commit makes those changes across the library and adds tests
for most of the iteration APIs to make sure that they follow the
above rules.

mwindow: allow memory-window files to deregister
Once a file is registered, there is no way to deregister it, even
after the structure that contains it is no longer needed and has been
freed. This may be the source of #624.
Allow and use the deregister function to remove our file from the
global list.

Actually do the mmap... unsurprisingly, this makes the indexer work on SFS
On RAM: the .idx and .pack files become links to a .lock and the original download respectively.
Assume some feature (such as record locking) supported by SFS but not JXFS or RAM: is required.

Migrate ODB files to new error handling
This migrates odb.c, odb_loose.c, odb_pack.c and pack.c to
the new style of error handling. Also got the unix and win32
versions of map.c. There are some minor changes to other
files but no others were completely converted.
This also contains an update to filebuf so that a zeroed out
filebuf will not think that the fd (== 0) is actually open
(and inadvertently call close() on fd 0 if cleaned up).
Lastly, this was built and tested on win32 and contains a
bunch of fixes for the win32 build which was pretty broken.

Move path related functions from fileops to path
This takes all of the functions that look up simple data about
paths (such as `git_futils_isdir`) and moves them over to path.h
(becoming `git_path_isdir`). This leaves fileops.h just with
functions that actually manipulate the filesystem or look at
the file contents in some way.
As part of this, the dir.h header which is really just for win32
support was moved into win32 (with some minor changes).

Fix #534: 64-bit issues in Windows
off_t is always 32 bits in Windows, which is beyond stupid, but we just
don't care anymore because we're using `git_off_t` which is assured to
be 64 bits on all platforms, regardless of compilation mode. Just
ensure that no casts to `off_t` are performed.
Also, the check for `off_t` overflows has been dropped, once again,
because the size of our offsets is always 64 bits on all platforms.
Fixes #534

odb_pack: don't do ambiguity checks for fully qualified SHA1 hashes
This makes libgit2 more closely match Git, which only checks for
ambiguous pack entries when given short hashes.
Note that the only time this is ever relevant is when a pack has the
same object more than once (it's happened in the wild, I promise).

Implement cooperative caching
When indexing a file with ref deltas, a temporary cache for the
offsets has to be built, as we don't have an index file yet. If the
user takes the responsiblity for filling the cache, the packing code
will look there first when it finds a ref delta.
