In protocol v0, when sending "shallow" lines, the server distinguishes
between lines caused by the remote repo being shallow and lines caused
by client-specified depth settings. Unless "--update-shallow" is
specified, there is a difference in behavior: refs that reach the former
"shallow" lines, but not the latter, are rejected. But in v2, the server
does not, and the client treats all "shallow" lines like lines caused by
client-specified depth settings.
Full restoration of v0 functionality is not possible without protocol
change, but we can implement a heuristic: if we specify any depth
setting, treat all "shallow" lines like lines caused by client-specified
depth settings (that is, unaffected by "--no-update-shallow"), but
otherwise, treat them like lines caused by the remote repo being shallow
(that is, affected by "--no-update-shallow"). This restores most of v0
behavior, except in the case where a client fetches from a shallow
repository with depth settings.
This patch causes a test that previously failed with
GIT_TEST_PROTOCOL_VERSION=2 to pass.

In fetch_pack(), be clearer that there is no shallow information before
the fetch when v2 is used - memset the struct shallow_info to 0 instead
of calling prepare_shallow_info().
This patch is in preparation for a future patch in which a v2 fetch
might call prepare_shallow_info() after shallow info has been retrieved
during the fetch, so I needed to ensure that prepare_shallow_info() is
not called before the fetch.

On platforms where "git fetch" is killed with SIGPIPE (e.g. OSX),
the upload-pack that runs on the other end that hangs up after
detecting an error could cause "git fetch" to die with a signal,
which led to a flakey test. "git fetch" now ignores SIGPIPE during
the network portion of its operation (this is not a problem as we

"git fsck --connectivity-only" omits computation necessary to sift

The Makefile uses 'find' utility to enumerate all the *.h header
files, which is expensive on platforms with slow filesystems; it

which is a trick similar to how all sources are enumerated to run
ETAGS on.

Recently the Git for Windows project started the upgrade process to
a MSYS2 runtime version based on Cygwin v3.x.
This has the very notable consequence that `$(uname -r)` no longer
reports a version starting with "2", but a version with "3".
That breaks our build, as df5218b4c3 (config.mak.uname: support MSys2,
2016-01-13) simply did not expect the version reported by `uname -r` to
depend on the underlying Cygwin version: it expected the reported
version to match the "2" in "MSYS2".
So let's invert that test case to test for *anything else* than a
version starting with "1" (for MSys). That should safeguard us for the
future, even if Cygwin ends up releasing versionsl like 314.272.65536.

Rather than parse options manually, which is both difficult to
read and error prone, parse options supplied to commit-tree
using the parse-options api.
It was discovered that the --no-gpg-sign option was documented
but not implemented in commit 70ddbd7767 (commit-tree: add missing
--gpg-sign flag, 2019-01-19), and the existing implementation
would attempt to translate the option as a tree oid. It was also
suggested earlier in commit 55ca3f99ae (commit-tree: add and document
--no-gpg-sign, 2013-12-13) that commit-tree should be migrated to
utilize the parse-options api, which could help prevent mistakes
like this in the future. Hence this change.
Also update the documentation to better describe that mixing
`-m` and `-F` options will correctly compose commit log messages in the
order in which the options are given.
In the process, mark various strings for translation.

Even though the newer "--type=color" option to "git config" is meant
to be upward compatible with the traditional "--get-color" option,
unlike the latter, its output is not an incomplete line that lack
the LF at the end. That makes it consistent with output of other
types like "git config --type=bool".
Document it, as it sometimes surprises unsuspecting users.

When running the SSH command as part of a fetch, Git will write "SendEnv
GIT_PROTOCOL" as an option if protocol v1 or v2 is used, but not v0.
Update all tests that check this to run Git with
GIT_TEST_PROTOCOL_VERSION=0.
I chose not to do a more thorough fix (for example, checking the value of
GIT_TEST_PROTOCOL_VERSION to see if the SendEnv check needs to be done)
because a set of patches [1] that unifies the handling of SSH options,
including writing "SendEnv GIT_PROTOCOL" regardless of protocol version,
is in progress. When that is done, this patch should be reverted, since
the functionality in here is no longer needed.
As of this patch, all tests pass if GIT_TEST_PROTOCOL_VERSION is set to
1.

Define a GIT_TEST_PROTOCOL_VERSION environment variable meant to be used
from tests. When set, this ensures protocol.version is at least the
given value, allowing the entire test suite to be run as if this
configuration is in place for all repositories.
As of this patch, all tests pass whether GIT_TEST_PROTOCOL_VERSION is
unset or set to 0. Some tests fail when GIT_TEST_PROTOCOL_VERSION is set
to 1 or 2, but this will be dealt with in subsequent patches.
