apply: Test for EOFNL mishandling when several hunks are processed
Introduce an unit test to validate that git_apply__patch() properly
handles EOFNL changes in case of patches with several hunks.

patch_parse: handle missing newline indicator in old file
When either the old or new file contents have no newline at the end of
the file, then git-diff(1) will print out a "\ No newline at end of
file" indicator. While we do correctly handle this in the case where the
new file has this indcator, we fail to parse patches where the old file
is missing a newline at EOF.
Fix this bug by handling and missing newline indicators in the old file.
Add tests to verify that we can parse such files.

patch_parse: do not depend on parsed buffer's lifetime
When parsing a patch from a buffer, we let the patch lines point into
the original buffer. While this is efficient use of resources, this also
ties the lifetime of the parsed patch to the parsed buffer. As this
behaviour is not documented anywhere in our API it is very surprising to
its users.
Untie the lifetime by duplicating the lines into the parsed patch. Add a
test that verifies that lifetimes are indeed independent of each other.

patch_parse: allow parsing ambiguous patch headers
The git patch format allows for having unquoted paths with whitespaces
inside. This format becomes ambiguous to parse, e.g. in the following
example:
diff --git a/file b/with spaces.txt b/file b/with spaces.txt
While we cannot parse this in a correct way, we can instead use the
"---" and "+++" lines to retrieve the file names, as the path is not
followed by anything here but spans the complete remaining line. Because
of this, we can simply bail outwhen parsing the "diff --git" header here
without an actual error and then proceed to just take the paths from the
other headers.

diff: implement function to calculate patch ID
The upstream git project provides the ability to calculate a so-called
patch ID. Quoting from git-patch-id(1):
A "patch ID" is nothing but a sum of SHA-1 of the file diffs
associated with a patch, with whitespace and line numbers ignored."
Patch IDs can be used to identify two patches which are probably the
same thing, e.g. when a patch has been cherry-picked to another branch.
This commit implements a new function `git_diff_patchid`, which gets a
patch and derives an OID from the diff. Note the different terminology
here: a patch in libgit2 are the differences in a single file and a diff
can contain multiple patches for different files. The implementation
matches the upstream implementation and should derive the same OID for
the same diff. In fact, some code has been directly derived from the
upstream implementation.
The upstream implementation has two different modes to calculate patch
IDs, which is the stable and unstable mode. The old way of calculating
the patch IDs was unstable in a sense that a different ordering the
diffs was leading to different results. This oversight was fixed in git
1.9, but as git tries hard to never break existing workflows, the old
and unstable way is still default. The newer and stable way does not
care for ordering of the diff hunks, and in fact it is the mode that
should probably be used today. So right now, we only implement the
stable way of generating the patch ID.

diff: treat binary patches with no data special
When creating and printing diffs, deal with binary deltas that have
binary data specially, versus diffs that have a binary file but lack the
actual binary data.
