When adding support for prefixing output of log and other commands using
--line-prefix, commit 660e113ce1 ("graph: add support for
--line-prefix on all graph-aware output", 2016-08-31) accidentally
broke rev-list --header output.
In order to make the output appear with a line-prefix, the flow was
changed to always use the graph subsystem for display. Unfortunately
the graph flow in rev-list did not use info->hdr_termination as it was
assumed that graph output would never need to putput NULs.
Since we now always use the graph code in order to handle the case of
line-prefix, simply replace putchar('\n') with
putchar(info->hdr_termination) which will correct this issue.
Add a test for the --header case to make sure we don't break it in the
future.

An "add --chmod=+x" test recently added by 610d55af0f ("add: modify
already added files when --chmod is given", 2016-09-14) used "xfoo3"
as a test file. The paths xfoo[1-3] were used by earlier tests for
symbolic links but they were expected to have been removed by the
time the execution reached this new test.
The removal with "git reset --hard" however happened in a pair of
earlier tests, both of which are protected by POSIXPERM,SANITY
prerequisites. Platforms and test environments that lacked these
would have seen xfoo3 as a leftover symbolic link that points at
somewhere else at this point of the sequence, and the chmod test
would have given a wrong result.

Calculating offsets involving a NULL pointer is undefined. It works in
practice (for now?), but we should not rely on it. Allocate first and
then simply refer to the flexible array member by its name instead of
performing pointer arithmetic up front. The resulting code is slightly
shorter, easier to read and doesn't rely on undefined behaviour.
NB: The cast to a (non-const) void pointer is necessary to keep support
for flexible array members declared as const.

In order for the receiving end of "git push" to inspect the
received history and decide to reject the push, the objects sent
from the sending end need to be made available to the hook and
the mechanism for the connectivity check, and this was done
traditionally by storing the objects in the receiving repository
and letting "git gc" to expire it. Instead, store the newly
received objects in a temporary area, and make them available by
reusing the alternate object store mechanism to them only while we
decide if we accept the check, and once we decide, either migrate
them to the repository or purge them immediately.

Add a simple pass-thru filter as example implementation for the Git
filter protocol version 2. See Documentation/gitattributes.txt, section
"Filter Protocol" for more info.
Signed-off-by: Lars Schneider <larsxschneider@gmail.com>

Git's clean/smudge mechanism invokes an external filter process for
every single blob that is affected by a filter. If Git filters a lot of
blobs then the startup time of the external filter processes can become
a significant part of the overall Git execution time.
In a preliminary performance test this developer used a clean/smudge
filter written in golang to filter 12,000 files. This process took 364s
with the existing filter mechanism and 5s with the new mechanism. See
details here: https://github.com/github/git-lfs/pull/1382
This patch adds the `filter.<driver>.process` string option which, if
used, keeps the external filter process running and processes all blobs
with the packet format (pkt-line) based protocol over standard input and
standard output. The full protocol is explained in detail in
`Documentation/gitattributes.txt`.
A few key decisions:
* The long running filter process is referred to as filter protocol
version 2 because the existing single shot filter invocation is
considered version 1.
* Git sends a welcome message and expects a response right after the
external filter process has started. This ensures that Git will not
hang if a version 1 filter is incorrectly used with the
filter.<driver>.process option for version 2 filters. In addition,
Git can detect this kind of error and warn the user.
* The status of a filter operation (e.g. "success" or "error) is set
before the actual response and (if necessary!) re-set after the
response. The advantage of this two step status response is that if
the filter detects an error early, then the filter can communicate
this and Git does not even need to create structures to read the
response.
* All status responses are pkt-line lists terminated with a flush
packet. This allows us to send other status fields with the same
protocol in the future.

Some processes might want to perform cleanup tasks before Git kills them
due to the 'clean_on_exit' flag. Let's give them an interface for doing
this. The feature is used in a subsequent patch.
Please note, that the cleanup callback is not executed if Git dies of a
signal. The reason is that only "async-signal-safe" functions would be
allowed to be call in that case. Since we cannot control what functions
the callback will use, we will not support the case. See 507d7804 for
