This commit adds basic git notes support to libgit2, namely:
* git_note_read
* git_note_message
* git_note_oid
* git_note_create
* git_note_remove
In the long run, we probably want to provide some convenience callback
mechanism for merging and moving (filter-branch) notes.

This is legacy compat stuff for when `deflateBound` is not defined, but
we're not embedding zlib and that function is always available. Kill
that with fire.
git_commit_create is supposed to update the given reference
"update_ref", but segfaulted in case of a yet to be born
reference. Fix it.

This lovely and much delayed release of libgit2 ships from the cold city
of Brussels, which is currently hosting FOSDEM 2012.
There's been plenty of changes since the latest stable release, here's a
full summary:
- Git Attributes support (see git2/attr.h)
There is now support to efficiently parse and retrieve information
from `.gitattribute` files in a repository. Note that this
information is not yet used e.g. when checking out files.
- .gitignore support
Likewise, all the operations that are affected by `.gitignore` files
now take into account the global, user and local ignores when
skipping the relevant files.
- Cleanup of the object ownership semantics
The ownership semantics for all repository subparts (index, odb,
config files, etc) has been redesigned. All these objects are now
reference counted, and can be hot-swapped in the middle of
execution, allowing for instance to add a working directory and an
index to a repository that was previously opened as bare, or to
change the source of the ODB objects after initialization.
Consequently, the repository API has been simplified to remove all
the `_openX` calls that allowed setting these subparts *before*
initialization.
- git_index_read_tree()
Git trees can now be read into the index.
- More reflog functionality
The reference log has been optimized, and new API calls to rename
and delete the logs for a reference have been added.
- Rewrite of the References code with explicit ownership semantics
The references code has been mostly rewritten to take into account
the cases where another Git application was modifying a repository's
references while the Library was running.
References are now explicitly loaded and free'd by the user, and
they may be reloaded in the middle of execution if the user suspects
that their values may have changed on disk. Despite the new
ownership semantics, the references API stays the same.
- Simplified the Remotes API
Some of the more complex Remote calls have been refactored into
higher level ones, to facilitate the usual `fetch` workflow of a
repository.
- Greatly improved thread-safety
The library no longer has race conditions when loading objects from
the same ODB and different threads at the same time. There's now
full TLS support, even for error codes. When the library is built
with `THREADSAFE=1`, the threading support must be globally
initialized before it can be used (see `git_threads_init()`)
- Tree walking API
A new API can recursively traverse trees and subtrees issuing callbacks for
every single entry.
- Tree diff API
There is basic support for diff'ing an index against two trees.
- Improved windows support
The Library is now codepage aware under Windows32: new API calls
allow the user to set the default codepage for the OS in order to
avoid strange Unicode errors.
After reviewing the gitignore support with Vicent, we came up
with a list of minor cleanups to prepare for merge, including:
* checking git_repository_config error returns
* renaming git_ignore_is_ignored and moving to status.h
* fixing next_line skipping to include \r skips
* commenting on where ignores are and are not included
Adds support for .gitignore files to git_status_foreach() and
git_status_file(). This includes refactoring the gitattributes
code to share logic where possible. The GIT_STATUS_IGNORED flag
will now be passed in for files that are ignored (provided they
are not already in the index or the head of repo).
Add support for git attribute macro definitions. Also, add
support for cache flush API to clear the attribute file content
cache when needed.
Additionally, improved the handling of global and system files,
making common utility functions in fileops and converting config
and attr to both use the common functions.
Adds a bunch more tests and fixed some memory leaks. Note that
adding macros required me to use refcounted attribute assignment
definitions, which complicated, but probably improved memory usage.
This adds APIs for querying git attributes. In addition to
the new API in include/git2/attr.h, most of the action is in
src/attr_file.[hc] which contains utilities for dealing with
a single attributes file, and src/attr.[hc] which contains
the implementation of the APIs that merge all applicable
attributes files.
Instead of just setting the value to NULL, which gives unwanted
results when asking for that variable after deleting it, delete the
variable from the list and re-write the file.

For each difference in the trees, the callback gets called with the
relevant information so the user can fill in their own data
structures.

The ownership semantics have been changed all over the library to be
consistent. There are no more "borrowed" or duplicated references.
Main changes:
- `git_repository_open2` and `3` have been dropped.
- Added setters and getters to hotswap all the repository owned
objects:
`git_repository_index`
`git_repository_set_index`
`git_repository_odb`
`git_repository_set_odb`
`git_repository_config`
`git_repository_set_config`
`git_repository_workdir`
`git_repository_set_workdir`
Now working directories/index files/ODBs and so on can be
hot-swapped after creating a repository and between operations.
- All these objects now have proper ownership semantics with
refcounting: they all require freeing after they are no longer
needed (the repository always keeps its internal reference).
- Repository open and initialization has been updated to keep in
mind the configuration files. Bare repositories are now always
detected, and a default config file is created on init.
- All the tests affected by these changes have been dropped from the
old test suite and ported to the new one.
reference_rename used to delete an old reflog file when renaming a
reference to not confuse git.git. Don't do this anymore but let the user
take care of writing a reflog entry.

There is no good reason to expose the negotiation as a different step
to downloading the packfile.

See `global.c` for a description of what we're doing.
When libgit2 is built with GIT_THREADS support, the threading system
must be explicitly initialized with `git_threads_init()`.
This new version of the references code is significantly faster and
hopefully easier to read.
External API stays the same. A new method `git_reference_reload()` has
been added to force updating a memory reference from disk. In-memory
references are no longer updated automagically -- this was killing us.
If a reference is deleted externally and the user doesn't reload the
memory object, nothing critical happens: any functions using that
reference should fail gracefully (e.g. deletion, renaming, and so on).
All generated references from the API are read only and must be free'd
by the user. There is no reference counting and no traces of generated
references are kept in the library.
There is no longer an internal representation for references. There is
only one reference struct `git_reference`, and symbolic/oid targets are
stored inside an union.
Packfile references are stored using an optimized struct with flex array
for reference names. This should significantly reduce the memory cost of
loading the packfile from disk.
Currently libgit2 shares pointers to its internal reference cache with
the user. This leads to several problems like invalidation of reference
pointers when reordering the cache or manipulation of the cache from
user side.
Give each user its own git_reference instead of leaking the internal
representation (struct reference).
Add the following new API functions:
* git_reference_free
* git_reference_is_packed

Our previous assumption that all paths in Windows are encoded in UTF-8
is rather weak, specially when considering that Git is
encoding-agnostic.
These set of functions allow the user to change the library's active
codepage globally, so it is possible to access paths and files on all
international versions of Windows.
Note that the default encoding here is UTF-8 because we assume that 99%
of all Git repositories will be in UTF-8.
Also, if you use non-ascii characters in paths, anywhere, please burn on
a fire.
