fileops: rename to "futils.h" to match function signatures
Our file utils functions all have a "futils" prefix, e.g.
`git_futils_touch`. One would thus naturally guess that their
definitions and implementation would live in files "futils.h" and
"futils.c", respectively, but in fact they live in "fileops.h".
Rename the files to match expectations.

blob: validate that blob sizes fit in a size_t
Our blob size is a `git_off_t`, which is a signed 64 bit int. This may
be erroneously negative or larger than `SIZE_MAX`. Ensure that the blob
size fits into a `size_t` before casting.

apply: handle exact renames
Deltas containing exact renames are special; they simple indicate that a
file was renamed without providing additional metadata (like the
filemode). Teach the reader to provide the file mode and use the
preimage's filemode in the case that the delta does not provide one.)

apply: validate unchanged mode when applying both
When applying to both the index and the working directory, ensure that
the working directory's mode matches the index's mode. It's not
sufficient to look only at the hashed object id to determine that the
file is unchanged, git also takes the mode into account.

reader: free is unused and unnecessary
None of the reader implementations actually allocate anything
themselves, so they don't need a free function. Remove it.

reader: apply working directory filters
When reading a file from the working directory, ensure that we apply any
necessary filters to the item. This ensures that we get the
repository-normalized data as the preimage, and further ensures that we
can accurately compare the working directory contents to the index
contents for accurate safety validation in the `BOTH` case.

reader: optionally validate index matches workdir
When using a workdir reader, optionally validate that the index contents
match the working directory contents.

apply: use preimage as the checkout baseline
Use the preimage as the checkout's baseline. This allows us to support
applying patches to files that are modified in the working directory
(those that differ from the HEAD and index). Without this, files will
be reported as (checkout) conflicts. With this, we expect the on-disk
data when we began the patch application (the "preimage") to be on-disk
during checkout.
We could have also simply used the `FORCE` flag to checkout to
accomplish a similar mechanism. However, `FORCE` ignores all
differences, while providing a preimage ensures that we will only
overwrite the file contents that we actually read.
Modify the reader interface to provide the OID to support this.

reader: a generic way to read files from repos
Similar to the `git_iterator` interface, the `git_reader` interface will
allow us to read file contents from an arbitrary repository-backed data
source (trees, index, or working directory).
