Improve docs, examples, warnings
This improves docs in some of the public header files, cleans
up and improves some of the example code, and fixes a couple
of pedantic warnings in places.

Add git_config_refresh() API to reload config
This adds a new API that allows users to reload the config if the
file has changed on disk. A new config callback function to
refresh the config was added.
The modified time and file size are used to test if the file needs
to be reloaded (and are now stored in the disk backend object).
In writing tests, just using mtime was a problem / race, so I
wanted to check file size as well. To support that, I extended
`git_futils_readbuffer_updated` to optionally check file size in
addition to mtime, and I added a new function `git_filebuf_stats`
to fetch the mtime and size for an open filebuf (so that the
config could be easily refreshed after a write).
Lastly, I moved some similar file checking code for attributes
into filebuf. It is still only being used for attrs, but it
seems potentially reusable, so I thought I'd move it over.

Move rename detection into new file
This improves the naming for the rename related functionality
moving it to be called `git_diff_find_similar()` and renaming
all the associated constants, etc. to make more sense.
I also moved the new code (plus the existing `git_diff_merge`)
into a new file `diff_tform.c` where I can put new functions
related to manipulating git diff lists.
This also updates the implementation significantly from the
last revision fixing some ordering issues (where break-rewrite
needs to be handled prior to copy and rename detection) and
improving config option handling.

Removed overwrite of CMAKE_C_FLAGS_DEBUG.
- No overwriting allows control from cmake cache or cmdline
- -g is already the CMake default
- -O0 is already gcc's default

Add git_diff_patch_print
This adds a `git_diff_patch_print()` API which is more like the
existing API to "print" a patch from an entire `git_diff_list`
but operates on a single `git_diff_patch` object.
Also, it rewrites the `git_diff_patch_to_str()` API to use that
function (making it very small).

Initial implementation of diff rename detection
This implements the basis for diff rename and copy detection,
although it is based on simple SHA comparison right now instead
of using a matching algortihm. Just as `git_diff_merge` can be
used as a post-pass on diffs to emulate certain command line
behaviors, there is a new API `git_diff_detect` which will
update a diff list in-place, adjusting some deltas to RENAMED
or COPIED state (and also, eventually, splitting MODIFIED deltas
where the change is too large into DELETED/ADDED pairs).
This also adds a new test repo that will hold rename/copy/split
scenarios. Right now, it just has exact-match rename and copy,
but the tests are written to use tree diffs, so we should be able
to add new test scenarios easily without breaking tests.
Use libcrypto's SHA-1 implementation when linking to it
libcryto's SHA-1 implementation is measurably better than the one that
ships with the library. If we link to it for HTTPS support already,
use that implementation instead.
Testing on a ~600MB of the linux repository, this reduces indexing
time by 40% and removes the hashing from the top spot in the perf
output.
Added `struct git_config_entry`: a git_config_entry contains the key, the value, and the config file level from which a config element was found.
Added `git_config_open_level`: build a single-level focused config object from a multi-level one.
We are now storing `git_config_entry`s in the khash of the config_file
