See lines 59-60 from https://github.com/libgit2/libgit2/blob/44b1ff4c1209c34360cc0c43761c40f5f5020886/src/filter.c which contain a couple of lines of code to ignore an EOF at the end of a file when detecting if it is a text file or not. These came from this contribution that Dmitry made to core Git back in 2008 (https://github.com/git/git/commit/f9dd4bf4e58af0b4828c7e7013080dba59f8a6b9) which was committed by Junio.

Dmitry gave his permission for these changes to be included in LibGit2 as well via email to vmg and myself

Permission obtained from Holger Weiss to include all of his contributions to Git into LibGit2. See https://github.com/git/git/commit/21e403a7b956a95a36f218439f82b1c8af869257

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.

Add git_config_level support when handling config files

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

This can occur after a manual modification of a config file.

blob: do not create temp files in the current path

 - make sure temporary streamed blobs are created under the
.git/objects folder and not in the current path, whatever it is.

 - do not make the name of the temp file depend on the hintpath.

Changes to CMake for packaging

Fix env variable tests with new Win32 path rules

Rename INSTALL_INC and INSTALL_BIN to INCLUDE_INSTALL_DIR and
BIN_INSTALL_DIR, which are more commonly used. This is also
consistent with the variable for the library path which is
already LIB_INSTALL_DIR.

The new Win32 global path search was not working with the
environment variable tests.  But when I fixed the test, the new
codes use of getenv() was causing more failures (presumably because
of caching on Windows ???).  This fixes the global file lookup to
always go directly to the Win32 API in a predictable way.
