Reorganize diff and add basic diff driver
This is a significant reorganization of the diff code to break it
into a set of more clearly distinct files and to document the new
organization. Hopefully this will make the diff code easier to
understand and to extend.
This adds a new `git_diff_driver` object that looks of diff driver
information from the attributes and the config so that things like
function content in diff headers can be provided. The full driver
spec is not implemented in the commit - this is focused on the
reorganization of the code and putting the driver hooks in place.
This also removes a few #includes from src/repository.h that were
overbroad, but as a result required extra #includes in a variety
of places since including src/repository.h no longer results in
pulling in the whole world.

Move crlf conversion into buf_text
This adds crlf/lf conversion functions into buf_text with more
efficient implementations that bypass the high level buffer
functions. They attempt to minimize the number of reallocations
done and they directly write the buffer data as needed if they
know that there is enough memory allocated to memcpy data.
Tests are added for these new functions. The crlf.c code is
updated to use the new functions.
Removed the include of buf_text.h from filter.h and just include
it more narrowly in the places that need it.

Add has_cr_in_index check to CRLF filter
This adds a check to the drop_crlf filter path to check it the
file in the index already has a CR in it, in which case this will
not drop the CRs from the workdir file contents.
This uncovered a "bug" in `git_blob_create_fromworkdir` where the
full path to the file was passed to look up the attributes instead
of the relative path from the working directory root. This meant
that the check in the index for a pre-existing entry of the same
name was failing.

Consolidate text buffer functions
There are many scattered functions that look into the contents of
buffers to do various text manipulations (such as escaping or
unescaping data, calculating text stats, guessing if content is
binary, etc). This groups all those functions together into a
new file and converts the code to use that.
This has two enhancements to existing functionality. The old
text stats function is significantly rewritten and the BOM
detection code was extended (although largely we can't deal with
anything other than a UTF8 BOM).

Add git_repository_hashfile to hash with filters
The existing `git_odb_hashfile` does not apply text filtering
rules because it doesn't have a repository context to evaluate
the correct rules to apply. This adds a new hashfile function
that will apply repository-specific filters (based on config,
attributes, and filename) before calculating the hash.

Alternate test for autocrlf with status
I couldn't get the last failing test to actually fail. This
is a different test suggested by @nulltoken which should fail.

Support reading attributes from index
Depending on the operation, we need to consider gitattributes
in both the work dir and the index. This adds a parameter to
all of the gitattributes related functions that allows user
control of attribute reading behavior (i.e. prefer workdir,
prefer index, only use index).
This fix also covers allowing us to check attributes (and
hence do diff and status) on bare repositories.
This was a somewhat larger change that I hoped because it had
to change the cache key used for gitattributes files.

error-handling: Repository
This also includes droping `git_buf_lasterror` because it makes no sense
in the new system. Note that in most of the places were it has been
dropped, the code needs cleanup. I.e. GIT_ENOMEM is going away, so
instead it should return a generic `-1` and obviously not throw
anything.

attr: Change the attribute check macros
The point of having `GIT_ATTR_TRUE` and `GIT_ATTR_FALSE` macros is to be
able to change the way that true and false values are stored inside of
the returned gitattributes value pointer.
However, if these macros are implemented as a simple rename for the
`git_attr__true` pointer, they will always be used with the `==`
operator, and hence we cannot really change the implementation to any
other way that doesn't imply using special pointer values and comparing
them!
We need to do the same thing that core Git does, which is using a
function macro. With `GIT_ATTR_TRUE(attr)`, we can change
internally the way that these values are stored to anything we want.
This commit does that, and rewrites a large chunk of the attributes test
suite to remove duplicated code for expected attributes, and to
properly test the function macro behavior instead of comparing
pointers.
