str: introduce `git_str` for internal, `git_buf` is external
libgit2 has two distinct requirements that were previously solved by
`git_buf`. We require:
1. A general purpose string class that provides a number of utility APIs
for manipulating data (eg, concatenating, truncating, etc).
2. A structure that we can use to return strings to callers that they
can take ownership of.
By using a single class (`git_buf`) for both of these purposes, we have
confused the API to the point that refactorings are difficult and
reasoning about correctness is also difficult.
Move the utility class `git_buf` to be called `git_str`: this represents
its general purpose, as an internal string buffer class. The name also
is an homage to Junio Hamano ("gitstr").
The public API remains `git_buf`, and has a much smaller footprint. It
is generally only used as an "out" param with strict requirements that
follow the documentation. (Exceptions exist for some legacy APIs to
avoid breaking callers unnecessarily.)
Utility functions exist to convert a user-specified `git_buf` to a
`git_str` so that we can call internal functions, then converting it
back again.

merge driver: remove `check` callback
Since the `apply` callback can defer, the `check` callback is not
necessary. Removing the `check` callback further makes the `payload`
unnecessary along with the `cleanup` callback.

merge driver: tests for set and unset merge attribute
Ensure that setting the merge attribute forces the built-in default
`text` driver and does *not* honor the `merge.default` configuration
option. Further ensure that unsetting the merge attribute forces
a conflict (the `binary` driver).

merge driver: introduce custom merge drivers
Consumers can now register custom merged drivers with
`git_merge_driver_register`. This allows consumers to support the
merge drivers, as configured in `.gitattributes`. Consumers will be
asked to perform the file-level merge when a custom driver is
configured.
